# Titanium.UI.WebView

> The web view allows you to open an HTML5 based view which can load either local or remote content.

- Source: https://titaniumsdk.com/docs/sdk/12.7.1/Titanium.UI.WebView
- Titanium SDK version: 12.7.1
- Kind: view
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK 0.8
- Extends: Titanium.UI.View
- Inheritance: Titanium.UI.View > Titanium.Proxy

Use the [Titanium.UI.createWebView](https://titaniumsdk.com/docs/sdk/Titanium.UI.md#createWebView) method or **`<WebView>`** Alloy element to create a web view.

Web views are more expensive to create than other native views because of the requirement to
load the HTML browser into memory.

The web view content can be any valid web content such as HTML, PDF, SVG or other WebKit supported
content types.

#### JavaScript Context in WebViews--Local vs. Remote Content

JavaScript in the web view executes in its own context.  The web view can interact with this
content, but most of this functionality is limited to local content.

**Local Scripts**

When running local web content
(that is, content that is included in the application's resources), scripts have
access to the Titanium namespace. In particular, when running local web content:

- You can use [Titanium.App.addEventListener](https://titaniumsdk.com/docs/sdk/Titanium.App.md#addEventListener) and
  [Titanium.App.fireEvent](https://titaniumsdk.com/docs/sdk/Titanium.App.md#fireEvent) to receive and send application-level events.

- Events can be logged using the [Titanium.API](https://titaniumsdk.com/docs/sdk/Titanium.API.md) logging methods.

**Remote Scripts**

Scripts downloaded from remote web servers cannot access the Titanium namespace.

To interact with remote content, wait until the content is loaded, then use the
[evalJS](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#evalJS) method to execute a JavaScript expression
inside the web view and retrieve the value of an expression.

You can inject the local `Ti.App.fireEvent` bindings yourself by adding a script element using
evalJS.

```js
webview.evalJS(
  'javascript=(function addBinding(){' +
    'var s=document.createElement("script");' +
    's.setAttribute("type","text/javascript");' +
    's.innerHTML="' + /* insert content of binding.min.js */ + '";'
    +
    'document.getElementsByTagName("body")[0].appendChild(s);' +
  '})()'
);
```
The `binding.min.js` is available in the [repository](https://github.com/tidev/titanium-sdk/tree/master/android/modules/ui/assets/Resources/ti.internal/webview).

For iOS check the example in [Titanium.UI.WebView.addScriptMessageHandler](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#addScriptMessageHandler).

#### Local JavaScript Files

During the build process for creating a package, all JavaScript files, that is, any file with a
'.js' extension, are removed and their content is encrypted and obfuscated into one resource,
causing these files to not load properly in a WebView if they are loaded externally.

For JavaScript files referenced in static local HTML files, these JavaScript files are omitted
from processing and left intact, which means they can be correctly loaded in the WebView.

For local JavaScript files not referenced in static local HTML files, for example, a
dynamically-generated HTML file referencing a local JavaScript file,
rename the file extension of the local JavaScript files to '.jslocal' instead of '.js'.

The build process for testing your application on the simulator, emulator or device does not
affect the loading of local JavaScript files.

#### iOS Platform Implementation Notes

On the iOS platform, the native web view handles scrolling and other related touch
events internally. If you add event listeners on the web view **or its parent views**
for any of the standard touch events (`touchstart`, `click`, and so on), these events
do not reach the native web view, and the user will not be able to scroll, zoom, click
on links, and so on. To prevent this default behavior, set
[willHandleTouches](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#willHandleTouches) to `false`.

In other words, you can have either Titanium-style events against the
web view instance, or internal JavaScript events in the DOM, but not both.

#### Android Platform Implementation Notes

**Android 4.4 and Later Support**

Starting with Android 4.4 (API Level 19), the WebView component is based off of Chromium,
introducing a number of changes to its rendering engine.  Web content may look or behave
differently depending on the Android version.  The WebView does not
have full feature parity with Chrome for Android.

By default, the Chromium WebView uses hardware acceleration, which may cause content to
fail to render. If the WebView fails to render the content, the web view will clear
itself, displaying only the default background color. The following log messages will be
displayed in the console:

```
[WARN] :   AwContents: nativeOnDraw failed; clearing to background color.
[INFO] :   chromium: [INFO:async_pixel_transfer_manager_android.cc(56)]
```

To workaround this issue, you can enable software rendering by setting the WebView's
[borderRadius](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#borderRadius) property to a value greater than zero.

If you are developing local HTML content and size your elements using percentages, the WebView may
not calculate the sizes correctly when hardware acceleration is enabled, resulting in the same
behavior previously mentioned.

To workaround this issue, you can use the previously mentioned workaround to enable software
rendering, use absolute size values or use the
[onresize](https://developer.mozilla.org/en-US/docs/Web/API/Window.onresize) event to set the
heights of the components.  For example, if you have a div element with an id set to `component`
that needs to use the entire web view, the following callback resizes the content to use the
full height of the web view:

``` js
window.onresize= function(){
    document.getElementById("component").style.height = window.innerHeight + 'px';
};
```

For more information, see the following topics:

  * [Android Developers: Migrating to WebView in Android 4.4](https://developer.android.com/guide/webapps/migrating.html)
  * [Google Chrome: WebView for Android](https://developer.chrome.com/multidevice/webview/overview)

**Plugin Support**

The Android web view supports native plugins.

To use plugin content, you must set the [pluginState](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#pluginState) property
to either [WEBVIEW_PLUGINS_ON](https://titaniumsdk.com/docs/sdk/Titanium.UI.Android.md#WEBVIEW_PLUGINS_ON) or
[WEBVIEW_PLUGINS_ON_DEMAND](https://titaniumsdk.com/docs/sdk/Titanium.UI.Android.md#WEBVIEW_PLUGINS_ON_DEMAND).

You must also call [pause](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#pause) when the current activity is
paused, to prevent plugin content from continuing to run in the background. Call
[resume](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#resume) when the current activity is resumed. You can
do this by adding listeners for the [Activity.pause](Titanium.Android.Activity.pause)
and [Activity.resume](Titanium.Android.Activity.resume) events.

**Accessing Cookies**

On Android, the web view uses the system cookie store which does not share cookies with the
[Titanium.Network.HTTPClient](https://titaniumsdk.com/docs/sdk/Titanium.Network.HTTPClient.md) cookie store. Developers can manage their cookies for both
cookie stores using the methods [Titanium.Network.addHTTPCookie](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#addHTTPCookie), [Titanium.Network.addSystemCookie](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#addSystemCookie),
[Titanium.Network.getHTTPCookies](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#getHTTPCookies), [Titanium.Network.getHTTPCookiesForDomain](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#getHTTPCookiesForDomain), [Titanium.Network.getSystemCookies](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#getSystemCookies),
[Titanium.Network.removeHTTPCookie](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#removeHTTPCookie), [Titanium.Network.removeHTTPCookiesForDomain](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#removeHTTPCookiesForDomain), [Titanium.Network.removeAllHTTPCookies](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#removeAllHTTPCookies),
[Titanium.Network.removeSystemCookie](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#removeSystemCookie), [Titanium.Network.removeAllSystemCookies](https://titaniumsdk.com/docs/sdk/Titanium.Network.md#removeAllSystemCookies).

**WKWebView**

With Titanium SDK 8.0.0, we now use WKWebView to implement Ti.UI.WebView (as Apple has deprecated UIWebView).
WKWebView has few restriction specially with local file accessing. For supporting custom-fonts with WKWebView
a little modification is required in the HTML files:

``` html
<style>
  @font-face
    {
      font-family: 'Lato-Regular';
      src: url('fonts/Lato-Regular.ttf');
    }
</style>
```

To have a WKWebView scale the page the same way as UIWebView, add the following meta tag to the HTML header:

``` html
<html>
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
  </head>
</html>
```

### Ti.UI.SIZE and WebViews

With Titanium 8.0.0+, [Titanium.UI.SIZE](https://titaniumsdk.com/docs/sdk/Titanium.UI.md#SIZE) does not work for WebViews. We recommend to give a **fixed height**
to [Titanium.UI.WebView](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md) (as noted in [TIDOC-3355](https://jira-archive.titaniumsdk.com/TIDOC-3355)).

As a workaround you can try to get the `document.body.scrollHeight` inside [Titanium.UI.WebView.load](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#load) event
of webview and set the height to webview. See following example.

``` js
var win = Ti.UI.createWindow();

var verticalView = Ti.UI.createView({layout: 'vertical', width: "100%", height: "100%"});

verticalView.add(Ti.UI.createLabel({text: 'Label 1', top: 30, width: Ti.UI.SIZE, height: Ti.UI.SIZE}));

var htmla = "<div style='font-family: Helvetica Neue; font-size:16px'><ul><li>Item 1</li><li>Item 2</li></ul></div>";
var html = "<!DOCTYPE html>";

html += "<html><head><meta name='viewport' content='width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0'><style type='text/css'>html {-webkit-text-size-adjust: none;}</style><script type='text/javascript'>document.ontouchmove = function(event){event.preventDefault();}</script></head><body style='overflow: hidden'>";
html += htmla;
html += "</body></html>";

var webview = Ti.UI.createWebView({left: '14dp', right: '14dp', top: '7dp', height: Ti.UI.SIZE, html: html, backgroundColor: "yellow"});

verticalView.add(webview);

verticalView.add(Ti.UI.createLabel({text: 'Label 2', top: 30, width: Ti.UI.SIZE, height: Ti.UI.SIZE}));

win.add(verticalView);

win.open();

webview.addEventListener('load', function(e) {
  var result = webview.evalJSSync('document.body.scrollHeight');
  Ti.API.info('webview height: ' + result);
  webview.height = result;
});
```

#### For More Information

See [Integrating Web
Content](https://titaniumsdk.com/guide/Titanium_SDK/Titanium_SDK_How-tos/Integrating_Web_Content/)
in the Titanium Mobile Guides for more information on using web views, including use
cases, more code examples, and best practices for web view content.

## Example: Basic Web View to External URL

Create a web view to a remote URL and open the window as modal.

``` js
var webview = Titanium.UI.createWebView({url:'http://www.titaniumsdk.com'});
var window = Titanium.UI.createWindow();
window.add(webview);
window.open({modal:true});
```

## Example: Alloy XML Markup

Previous example as an Alloy view.

``` xml
<Alloy>
    <Window id="win" modal="true">
        <WebView id="webview" url="http://www.titaniumsdk.com" />
    </Window>
</Alloy>
```

## Example: Listening to Web View properties in iOS

Create a web view and listen 'title' property of web view.

``` js
var webview = Ti.UI.createWebView({
    url:'http://www.titaniumsdk.com'
});
webview.startListeningToProperties([ 'title' ]);
webview.addEventListener('title', function(e) {
    alert('Title is : -' +e.value);
});
var window = Ti.UI.createWindow();
window.add(webview);
window.open();
```

## Example: Usage of allowedURLSchemes and handleurl in iOS

Create a web view and listen 'handleurl' event to open url from Titanium platform.

``` js
var webview = Ti.UI.createWebView({
    url: 'https://www.google.com',
    allowedURLSchemes: [ 'https', 'http' ]
});

webview.addEventListener('handleurl', function(e) {
    var handler = e.handler;
    Ti.Platform.openURL(e.url);
    handler.invoke(Ti.UI.iOS.ACTION_POLICY_CANCEL);
});
var window = Ti.UI.createWindow();
window.add(webview);
window.open();
```

## Properties

### allowedURLSchemes

- Type: Array<String>
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0

List of allowed URL schemes for the web view.

See the example section "Usage of allowedURLSchemes and handleurl in iOS".

### allowFileAccess

- Type: Boolean
- Platforms: Android
- Since: Titanium SDK 12.1.0
- Default: `false`

A Boolean value indicating file access within WebView.

Set to `true` to enable access to local files for examples images stored in [Titanium.Filesystem.applicationDataDirectory](https://titaniumsdk.com/docs/sdk/Titanium.Filesystem.md#applicationDataDirectory). If false resources are still accessible using `file:///android_asset` and `file:///android_res`. Do not enable this if your app accepts arbitrary URLs from external sources.

### allowsBackForwardNavigationGestures

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0
- Default: `false`

A Boolean value indicating whether horizontal swipe gestures will trigger back-forward list navigations.

### allowsLinkPreview

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 5.4.0, iPad 5.4.0, macOS 9.2.0
- Default: `false`

A Boolean value that determines whether pressing on a link displays a preview of the
destination for the link.

This property is available on devices that support 3D Touch. Default value is `false`.

If you set this value to `true` for a web view, users (with devices that support 3D Touch)
can preview link destinations, and can preview detected data such as addresses, by pressing on links.
Such previews are known to users as peeks. If a user presses deeper, the preview navigates (or pops,
in user terminology) to the destination. Because pop navigation switches the user from your app to
Safari, it is opt-in, by way of this property, rather default behavior for this class.

### assetsDirectory

- Type: String
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 9.0.0, iPad 9.0.0, macOS 9.2.0

Path of file or directory to allow read access by the WebView.

Use this property to change the resources the web view has access to when loading the content of a local file.
By default the web view only has access to files inside the same directory as the loaded file. To reference
resources from other directories (e.g. a parent directory) change this property accordingly.

If assetsDirectory references a single file, only that file may be loaded. If assetsDirectory references a
directory, files inside that directory may be loaded.

This property needs to be set before [url](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#url) is assigned to a local file.

### blacklistedURLs

- Type: Array<String>
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK Android 5.4.0, iPhone 6.1.0, iPad 6.1.0, macOS 9.2.0
- DEPRECATED since 9.2.0. Use the <Titanium.UI.WebView.blockedURLs> property instead.

An array of url strings to blacklist.

An array of url strings to blacklist. This will stop the webview from going to urls listed in
the blacklist. Note, this only applies in the links clicked inside the webview. The first website
that is loaded will not be stopped even if it matches the blacklist.

### blockedURLs

- Type: Array<String>
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK 9.2.0

An array of url strings to be blocked.

An array of url strings to be blocked from loading. This will stop the webview from going to urls
listed in this array. Note that this only applies to the links tapped on by the end-user.
The first website that is loaded will not be stopped, even if it is listed in the blocklist.

### cacheMode

- Type: Number
- Platforms: Android
- Since: Titanium SDK 3.2.0
- Default: `<Titanium.UI.Android.WEBVIEW_LOAD_DEFAULT>`

Determines how a cache is used in this web view.

Accepts: `Titanium.UI.Android.WEBVIEW_LOAD_CACHE_ELSE_NETWORK`, `Titanium.UI.Android.WEBVIEW_LOAD_CACHE_ONLY`, `Titanium.UI.Android.WEBVIEW_LOAD_DEFAULT`, `Titanium.UI.Android.WEBVIEW_LOAD_NO_CACHE`

### cachePolicy

- Type: Number
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0

The cache policy for the request.

Accepts: `Titanium.UI.iOS.CACHE_POLICY_RELOAD_IGNORING_LOCAL_CACHE_DATA`, `Titanium.UI.iOS.CACHE_POLICY_RETURN_CACHE_DATA_DONT_LOAD`, `Titanium.UI.iOS.CACHE_POLICY_RETURN_CACHE_DATA_ELSE_LOAD`, `Titanium.UI.iOS.CACHE_POLICY_USE_PROTOCOL_CACHE_POLICY`

### configuration

- Type: Titanium.UI.iOS.WebViewConfiguration
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0

The configuration for the new web view.

This property can only be set when creating the webview and will be ignored when set afterwards.

### data

- Type: Titanium.Blob | Titanium.Filesystem.File
- Platforms: Android, iPhone, iPad, macOS

Web content to load.

Android only supports loading data from a `Blob`, not a `File`.

See also: [url](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#url) and [html](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#html).

### disableBounce

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Default: `false`

Determines whether the view will bounce when scrolling to the edge of the scrollable region.

Set to `true` to disable the bounce effect.

### disableContextMenu

- Type: Boolean
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK Android 6.1.0, iPhone 6.1.0, iPad 6.1.0, macOS 9.2.0
- Default: `false`

Determines whether or not the webview should not be able to display the context menu.

Set to `true` to disable the context menu. Note that disabling the context menu will
also disable the text selection on iOS.

### enableJavascriptInterface

- Type: Boolean
- Platforms: Android
- Since: Titanium SDK 3.6.0
- Default: `true`

Enable adding javascript interfaces internally to webview prior to JELLY_BEAN_MR1 (Android 4.2)

This property is introduced to prevent a security issue with older devices (< JELLY_BEAN_MR1)

### enableZoomControls

- Type: Boolean
- Platforms: Android
- Since: Titanium SDK 1.8.0
- Default: `true`

If `true`, zoom controls are enabled.

### handlePlatformUrl

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 3.3.0, iPad 3.3.0, macOS 9.2.0
- Default: `undefined. Behaves as if false`
- DEPRECATED since 8.0.0. This property in no more supported in Titanium SDK 8.0.0+. Use property <Titanium.UI.WebView.allowedURLSchemes> in conjuction with <Titanium.UI.WebView.handleurl>. See the example section "Usage of allowedURLSchemes and handleurl in iOS".

Lets the webview handle platform supported urls

By default any urls that are not handled by the Titanium platform but can be handled by the
shared application are automatically sent to the shared application and the webview does not
open these. When this property is set to `true` the webview will attempt to handle these
urls and they will not be sent to the shared application. An example is links to telephone
numbers.

### hideLoadIndicator

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 3.0.0, iPad 3.0.0, macOS 9.2.0
- Default: `false`

Hides activity indicator when loading remote URL.

### html

- Type: String
- Platforms: Android, iPhone, iPad, macOS

HTML content of this web view.

See [setHtml](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#setHtml) for additional parameters that can be
specified when setting HTML content.

The web view's content can also be set using the [data](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#data) or
[url](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#url) properties.

If you want to get the HTML content of a remote URL you can grab it with this `evalJS` call:
``` js
webview.addEventListener('load', function() {
  webview.evalJS('document.documentElement.outerHTML.toString()', function(data) {
    console.log(data);
  });
});
```

See also: [data](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#data) and [url](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#url).

### ignoreSslError

- Type: Boolean
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK Android 3.0.0, iPhone 6.0.2, iPad 6.0.2, macOS 9.2.0
- Default: `undefined but behaves as false`

Controls whether to ignore invalid SSL certificates or not.

If set to `true`, the web page loads despite having an invalid SSL certificate.
If set to `false`, a web page with an invalid SSL certificate does not load.

iOS Note: As soon as you set this property to `true`, iOS will cache the response
for the lifetime of the current web view.

### keyboardDisplayRequiresUserAction

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 6.1.0, iPad 6.1.0, macOS 9.2.0
- Default: `undefined but behaves as true`

A Boolean value indicating whether web content can programmatically display the keyboard.

When this property is set to true, the user must explicitly tap the elements in the web view
to display the keyboard (or other relevant input view) for that element. When set to false,
a focus event on an element causes the input view to be displayed and associated with
that element automatically.

### LAYER_TYPE_HARDWARE

- Type: Number
- Platforms: Android
- Since: Titanium SDK 12.7.0
- Permission: read-only

Hardware rendering mode

### LAYER_TYPE_NONE

- Type: Number
- Platforms: Android
- Since: Titanium SDK 12.7.0
- Permission: read-only

Default rendering mode

### LAYER_TYPE_SOFTWARE

- Type: Number
- Platforms: Android
- Since: Titanium SDK 12.7.0
- Permission: read-only

Software rendering mode

### layerType

- Type: Number
- Platforms: Android
- Since: Titanium SDK 12.7.0
- Default: `<Titanium.UI.WebView.LAYER_TYPE_NONE>`

A value indicating the render mode of the WebView

Set to Ti.UI.WebView.LAYER_TYPE_SOFTWARE (software rendering) if you use `Ti.Media.takeScreenshot()` or `toImage()` and the WebView contains local HTML files.
Otherwise the WebView might be empty in the screenshot/image. If you change the setting you will have to assing the HTML content again.

Accepts: `Titanium.UI.WebView.LAYER_TYPE_HARDWARE`, `Titanium.UI.WebView.LAYER_TYPE_NONE`, `Titanium.UI.WebView.LAYER_TYPE_SOFTWARE`

### lightTouchEnabled

- Type: Boolean
- Platforms: Android
- Since: Titanium SDK 3.2.0
- Default: `true`

Enables using light touches to make a selection and activate mouseovers.

Setting this property solves the problem of web links with specific length not triggering a link click in Android.

This is only an Android specific property and has no effect starting from API level 18.

This flag is `true` by default to retain backwards compatibility with previous
behavior.

### loading

- Type: Boolean
- Platforms: iPhone, iPad, macOS

Indicates if the webview is loading content.

### mixedContentMode

- Type: Boolean
- Platforms: Android
- Since: Titanium SDK 7.5.0
- Default: `false`

If `true`, allows the loading of insecure resources from a secure origin.

On iOS this functionality can be set in the `<plist>` section of the tiapp.xml
using the `NSAllowsArbitraryLoads` key as part of the App Transport Security.
The plist key is enabled by default, allowing arbitrary loads to be processed.

### onCreateWindow

- Type: Callback<Object>
- Platforms: Android
- Since: Titanium SDK 2.1.0

Callback function called when there is a request for the application to create a new window
to host new content.

For example, the request is triggered if a web page wants to open a URL in a new
window.  By default, Titanium will open a new full-size window to host the new content.
Use the callback to override the default behavior.

The callback needs to create a new WebView object to host the content in and add the WebView to the
application UI. The callback must return either a WebView object to host the content in or `null` if
it does not wish to handle the request.

The callback is passed a dictionary with two boolean properties:

  * `isDialog`: set to true if the content should be opened in a dialog window rather than a
    full-size window.
  * `isUserGesture`: set to true if the user initiated the request with a gesture, such as
    tapping a link.

The following example opens new web content in a new tab rather than a new window:

``` js
var tabGroup = Ti.UI.createTabGroup(),
    win = Ti.UI.createWindow(),
    tab = Ti.UI.createTab({window: win, title: 'Start Page'}),
    webview = Ti.UI.createWebView({ url:'index.html'});

webview.onCreateWindow = function(e) {
    var newWin = Ti.UI.createWindow(),
        newWebView = Ti.UI.createWebView(),
        newTab = Ti.UI.createTab({window: newWin, title: 'New Page'});
    newWin.add(newWebView);
    tabGroup.addTab(newTab);
    return newWebView;
};

win.add(webview);
tabGroup.addTab(tab);
tabGroup.open();
```

### onlink

- Type: Callback<OnLinkURLResponse>
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK Android 7.5.0, iPhone 7.5.0, iPad 7.5.0, macOS 9.2.0

Fired before navigating to a link.

The callback will be called before navigating to the link. The Boolean return value of the
callback will determine if the link will be navigated or discarded.

### overScrollMode

- Type: Number
- Platforms: Android
- Since: Titanium SDK 3.1.0
- Default: `Titanium.UI.Android.OVER_SCROLL_ALWAYS`

Determines the behavior when the user overscrolls the view.

Accepts: `Titanium.UI.Android.OVER_SCROLL_ALWAYS`, `Titanium.UI.Android.OVER_SCROLL_IF_CONTENT_SCROLLS`, `Titanium.UI.Android.OVER_SCROLL_NEVER`

### PDF_PAGE_DIN_A1

### pluginState

- Type: Number
- Platforms: Android
- Since: Titanium SDK 1.8.0
- Default: `<Titanium.UI.Android.WEBVIEW_PLUGINS_OFF>`

Determines how to treat content that requires plugins in this web view.

This setting affects the loading of content that requires web plugins.

To enable hardware acceleration, add the `tool-api-level` and
`manifest` elements shown below inside the `android` element in your `tiapp.xml` file.

``` xml
<android xmlns:android="http://schemas.android.com/apk/res/android">
    <tool-api-level>11</tool-api-level>
    <manifest>
        <application android:hardwareAccelerated="true"/>
    </manifest>
</android>
```

See Android documentation for
[WebSettings.PluginState](https://developer.android.com/reference/android/webkit/WebSettings.PluginState.html).

This property only works on Android devices at API Level 8 or greater.

Accepts: `Titanium.UI.Android.WEBVIEW_PLUGINS_OFF`, `Titanium.UI.Android.WEBVIEW_PLUGINS_ON`, `Titanium.UI.Android.WEBVIEW_PLUGINS_ON_DEMAND`

### progress

- Type: Number
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK Android 9.1.0, iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0
- Permission: read-only

An estimate of what fraction of the current navigation has been loaded.

This value ranges from 0.0 to 1.0 based on the total number of bytes expected
to be received, including the main document and all of its potential subresources.
After loading completes, the progress remains at 1.0 until a new download starts,
at which point progress is reset to 0.0.

### requestHeaders

- Type: Dictionary
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK Android 6.1.0, iPhone 6.1.0, iPad 6.1.0, macOS 9.2.0

Sets extra request headers for this web view to use on subsequent URL requests.

Setting this property allows you to set custom headers to the URL requests.
The parameter will be key-value pairs: `{"Custom-field1":"value1", "Custom-field2":"value2"}`

On Android you should avoid Calling `setRequestHeaders()` right after `createWebView()`. Use the `requestHeaders` property
inside `createWebView()` or put it inside the window `open` event.

### scalesPageToFit

- Type: Boolean
- Platforms: Android, iPhone, iPad, macOS
- Default: ``false` on iOS. On Android, `false` when content is specified as a local URL,
`true` for any other kind of content (remote URL, `Blob`, or `File`).
`

If `true`, scale contents to fit the web view.

On iOS, setting this to `true` sets the initial zoom level to show the entire
page, and enables the user to zoom the web view in and out. Setting this to
`false` prevents the user from zooming the web view.

On Android, only controls the initial zoom level.

### scrollbars

- Type: Number
- Platforms: Android
- Since: Titanium SDK 12.3.0
- Default: `<Titanium.UI.Android.WEBVIEW_SCROLLBARS_DEFAULT>`

Enable or disable horizontal/vertical scrollbars in a WebView.

Accepts: `Titanium.UI.Android.WEBVIEW_SCROLLBARS_DEFAULT`, `Titanium.UI.Android.WEBVIEW_SCROLLBARS_HIDE_ALL`, `Titanium.UI.Android.WEBVIEW_SCROLLBARS_HIDE_HORIZONTAL`, `Titanium.UI.Android.WEBVIEW_SCROLLBARS_HIDE_VERTICAL`

### scrollsToTop

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 2.0.0, iPad 2.0.0, macOS 9.2.0
- Default: `true`

Controls whether the scroll-to-top gesture is effective.

The scroll-to-top gesture is a tap on the status bar; The default value of this property is true.
This gesture works when you have a single visible web view.
If there are multiple table views, web views, text areas, and/or scroll views visible,
you will need to disable (set to false) on the above views you DON'T want this
behaviour on. The remaining view will then respond to scroll-to-top gesture.

### secure

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0
- Permission: read-only

A Boolean value indicating whether all resources on the page have been loaded through
securely encrypted connections.

### selectionGranularity

- Type: Number
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0
- Permission: read-only

The level of granularity with which the user can interactively select content in the web view.

Accepts: `Titanium.UI.iOS.SELECTION_GRANULARITY_CHARACTER`, `Titanium.UI.iOS.SELECTION_GRANULARITY_DYNAMIC`

### timeout

- Type: Number
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0

The timeout interval for the request, in seconds.

### title

- Type: String
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0
- Permission: read-only

Returns page title of webpage.

### url

- Type: String
- Platforms: Android, iPhone, iPad, macOS

URL to the web document.

This property changes as the content of the webview changes (such as when the user
clicks a hyperlink inside the web view).

See also: [data](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#data) and [html](https://titaniumsdk.com/docs/sdk/Titanium.UI.WebView.md#html).

### userAgent

- Type: String
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK Android 2.0.0, iPhone 6.1.0, iPad 6.1.0, macOS 9.2.0
- Default: `System default user-agent value.`

The User-Agent header used by the web view when requesting content.

On the iOS platform, this is not per-webview. Once you have set this property for a webview
it will not change for same. But while creating new webview it can be changed to new user agent.

On Android, changing the user agent after the webview has begun loading content may cause
the webview to reload and fire multiple `load` or `beforeload` events. Developers should provide the
user agent value in the creation properties to avoid the reload and multiple events firing.

### willHandleTouches

- Type: Boolean
- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 1.8.2, iPad 1.8.2, macOS 9.2.0
- Default: `true`

Explicitly specifies if this web view handles touches.

On the iOS platform, if this web view **or any of its parent views** have touch
listeners, the Titanium component intercepts **all** touch events. This
prevents the user from interacting with the native web view components.

Set this flag to `false` to disable the default behavior. Setting this property to `false`
allows the user to interact with the native web view and still honor any `touch` events sent to
its parents. No `touch` events will be generated when the user interacts with the web view itself.

Set this flag to `true` if you want to receive touch events from the web view and
the user does not need to interact with the web content directly.

This flag is `true` by default to retain backwards compatibility with previous
behavior.

### zoomLevel

- Type: Number
- Platforms: Android, iPhone, iPad, macOS
- Since: Titanium SDK Android 7.3.0, iPhone 7.3.0, iPad 7.3.0, macOS 9.2.0
- Default: `undefined. Behaves as no zoom applied.`

Manage the zoom-level of the current page.

## Methods

### addScriptMessageHandler

- Platforms: iPhone, iPad, macOS
- Since: Titanium SDK iPhone 8.0.0, iPad 8.0.0, macOS 9.2.0

Adds a script message handler.

Adding a script message handler with name 'name' causes the JavaScript function
window.webkit.messageHandlers.name.postMessage(messageBody) to be defined in all
frames in the web view. You use the same 'name' in your webview's html.
Example JS code for the webview page:
```
<script type="text/javascript">
    window.webkit.messageHandlers.yourHandlerName.postMessage({
        message: 'This is an example string.'
    });
</script>
```
Connection to the webview:
```js
webView.addScriptMessageHandler('yourHandlerName');
webView.addEventListener('message', ({ name }) => {
    if (name === 'yourHandlerName') {
        console.log(e.body.message);
    }
});
```

Parameters:

- `handlerName` (String): The name of the message handler and should not be '_Ti_', as titanium is using it for internal usage.

### createPDF

- Platforms: Android, iPhone, iPad
- Since: Titanium SDK Android 12.1.0, iPhone 9.2.0, iPad 9.2.0
- Requires: iOS 14.0+

Create a PDF document representation from the web page currently displayed in the WebView.

If the data is written to a file the resulting file is a valid PDF document.

The Android version uses an object as a parameter instead of a callback function:
```js
$.webview.createPDF({
  pageWidth: 5000,
  pageHeight: 72000,
  success: function(e) {
    // e.data <- the PDF data
  }
});
```
You can use either `pageWidth`/`pageHeight` or a `pageSize` constant like PDF_PAGE_DIN_A4.

Parameters:

- `pageWidth` (Number): The width in mils (thousandths of an inch) of the PDF (Android only)
- `pageHeight` (Number): The height in mils (thousandths of an inch) of the PDF (Android only)
- `pageSize` (Number): Predfined size. (Android only)
- `showMenu` (Boolean): Will show Androids printing menu. No sucess callback afterwards. (Android only)
- `firstPageOnly` (Boolean): Only print first page (Android only)
- `success` (Callback<DataCreationResultAndroid>): Function to call upon pdf creation. (Android only)
- `callback` (Callback<DataCreationResult>): Function to call upon pdf creation. (iOS only)

### createWebArchive

- Platforms: iPhone, iPad
- Since: Titanium SDK 9.2.0
- Requires: iOS 14.0+

Create WebKit web archive data representing the current web content of the WebView.

WebKit web archive data represents a snapshot of web content. It can be loaded into a WebView directly,
and saved to a file for later use.

Parameters:

- `callback` (Callback<DataCreationResult>): Function to call upon web archive creation.

### evalJS

- Platforms: Android, iPhone, iPad, macOS

Evaluates a JavaScript expression inside the context of the web view and
optionally, returns a result. If a callback function is passed in as second argument,
the evaluation will take place asynchronously and the the callback function will be called with the result.

The JavaScript expression must be passed in as a string. If you are passing in any objects,
you must serialize them to strings using [stringify](https://titaniumsdk.com/docs/sdk/Global.md).

The `evalJS` method returns a string representing the value of the expression. For
example, the following call retrieves the `document.title` element from the
document currently loaded into the web view.

``` js
var docTitle = myWebView.evalJS('document.title');
```

It is not necessary to include `return` in the JavaScript. In fact, the following
call returns the empty string:

``` js
myWebView.evalJS('return document.title');
```

The `evalJS` variant with a second callback argument executes asynchronously.

``` js
myWebView.evalJS('document.title', function (result) {
  // Manipulate the result here
});
```

Parameters:

- `code` (String): JavaScript code as a string. The code will be evaluated inside the web view context.
- `callback` (Callback<String>, optional): Optional callback function for the result. Required on Windows, optional on iOS/Android.

Returns: String - Result of the evaluation. May be null if the asynchronous variant of this method is called.
