您可以这样做,但只能在支持新HTML5 History API的浏览器中进行。您将需要使用ExternalInterface
与 JavaScript 层合作。Flash 方面可能如下所示:
package {
import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.external.ExternalInterface;
import flash.text.TextField;
import flash.text.TextFieldAutoSize;
public class Test extends Sprite {
protected var _text:TextField;
function Test() {
var b:Sprite = new Sprite;
b.graphics.beginFill(0xff0000);
b.graphics.drawRect(0, 0, 32, 32);
b.graphics.endFill();
b.addEventListener(MouseEvent.MOUSE_DOWN, function(e:MouseEvent):void {
pushState('/test/foo');
});
addChild(b);
b = new Sprite;
b.x = 64;
b.graphics.beginFill(0x0000ff);
b.graphics.drawRect(0, 0, 32, 32);
b.graphics.endFill();
b.addEventListener(MouseEvent.MOUSE_DOWN, function(e:MouseEvent):void {
pushState('/test/bar');
});
addChild(b);
_text = new TextField();
_text.autoSize = TextFieldAutoSize.LEFT;
_text.y = 64;
addChild(_text);
if (ExternalInterface.available) {
ExternalInterface.addCallback('onPopState', onPopState);
ExternalInterface.call('test.onReady');
} else {
_text.text = 'external interface not available';
}
}
protected function onPopState(path:String):void {
_text.appendText("flash onPopState: " + path + "\n");
}
protected function pushState(path:String):void {
_text.appendText("flash pushState: " + path + "\n");
ExternalInterface.call('history.pushState', null, null, path);
}
}
}
JavaScript 端可能如下所示:
<!DOCTYPE html>
<html>
<body>
<script type="text/javascript">
if (!!(window.history && history.pushState)) {
var test = {
onPopState: function(event) {
if (this.embed) {
this.embed.onPopState(location.pathname);
}
},
onReady: function() {
var embed = document.getElementById('flash');
this.embed = embed.getElementsByTagName('object')[0] || embed;
this.embed.onPopState(location.pathname);
}
};
window.addEventListener('popstate', function(event) {
test.onPopState(event);
}, false);
} else {
alert('This browser does not support the history API');
}
</script>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
id="flash" width="780" height="420">
<param name="movie" value="test.swf" />
<!--[if !IE]>-->
<object type="application/x-shockwave-flash"
data="test.swf" width="780" height="420">
<!--<![endif]-->
<p>Flash is required</p>
<!--[if !IE]>-->
</object>
<!--<![endif]-->
</object>
</body>
</html>
在本例中,onPopState
每当路径更改时调用,并pushState
调用以更改 URL。您可以单击示例中的红色和蓝色框来更改 Flash 中的 URL。
如果您想这样做并且必须支持较旧的浏览器,那么当不支持历史 API 时,您可能希望回退到哈希标签。理想情况下,您可以在 JS 层中对其进行抽象,这样 Flash 代码就不必知道正在使用哪个。我建议使用第三方库,例如History.js,因为它会为您处理哈希回退。
