Displaying HTML content in mobile apps
JavaScript URI
You can use a JavaScript URI to call a function defined in the HTML page that is loaded by a StageWebView object.
The function you call using the JavaScript URI runs in the context of the loaded web page. The following example uses
a StageWebView object to call a JavaScript function:
package {
import flash.display.*;
import flash.geom.Rectangle;
import flash.media.StageWebView;
public class WebView extends Sprite
{
public var webView:StageWebView = new StageWebView();
public function WebView()
{
var htmlString:String = "" +
"" +
"function callURI(){" +
"alert(\"You clicked me!!\");"+
"}" +
"Click Me" +
"";
webView.stage = this.stage;
webView.viewPort = new Rectangle( 0, 0, stage.stageWidth, stage.stageHeight );
webView.loadString( htmlString );
}
}
}

Navigation events
When a user clicks a link in the HTML, the StageWebView object dispatches a locationChanging event. You can call
the preventDefault() method of the event object to stop the navigation. Otherwise, the StageWebView object
navigates to the new page and dispatches a locationChange event. When the page load has finished, the
StageWebView dispatches a complete event.
A locationChanging event is dispatched on every HTML redirect. The locationChange and complete events are
dispatched at the appropriate time.
On iOS, a locationChanging event is dispatched before a locationChange event, except for the first loadURL() or
loadString() methods. A locationChange event is also dispatched for navigational changes through iFrames and
Frames.
The following example illustrates how you can prevent a location change and open the new page in the system browser
instead.
