js 怎样调用AS

[qing583538]

我想用JS调用别人开发的SWF里的一个方法，在网上找了一些方法都不成功，有高手懂吗？
下面是swf的代码，
package player_fla
{
...
dynamic public class MainTimeline extends MovieClip
{
....
public function MainTimeline()
{
addFrameScript(0, frame1);
return;
}// end function

public function ncOnStatus(event:NetStatusEvent)
{
trace("nc: " + event.info.code + " (" + event.info.description + ")");
if (event.info.code == "NetConnection.Connect.Success")
{
playLiveStream();
videoLastW = 0;
videoLastH = 0;
videoObj.visible = true;
}
else if (event.info.code == "NetConnection.Connect.Failed")
{
prompt.text = "Connection failed: Try rtmp://[server-ip-address]:[port]/rtplive";
}
else if (event.info.code == "NetConnection.Connect.Rejected")
{
prompt.text = event.info.description;
}
return;
}// end function

public function getPlayState()
{
return m_playstate;
}// end function

public function nsOnStatus(event:NetStatusEvent)
{
....
}// end function

public function enterFullscreen(event:MouseEvent)
{
...
}// end function

public function doStop()
{
nsPlay.close();
videoObj.clear();
if (videoSizeTimer)
{
clearInterval(videoSizeTimer);
}
videoSizeTimer = 0;
videoLastW = 0;
videoLastH = 0;
nsPlay = null;
nc.close();
nc = null;
prompt.text = "";
if (debugInterval != 0)
{
clearInterval(debugInterval);
}
debugInterval = 0;
m_playstate = 0;
return;
}// end function

public function updateStreamValues()
{
var _loc_1:String = "";
if (nsPlay != null)
{
_loc_1 = Math.round(nsPlay.currentFPS * 1000) / 1000 + " fps/" + Math.round(nsPlay.bufferLength * 1000) / 1000 + " secs";

怎样用JS调用doPlay(),doStop(),getPlayState()这三个方法？

[qing583538]

没有人做过吗，自己顶一下

[Loop-break]

js不能调用AS

[wern0565]

js中声明的object，用它来调用as中使用ExternalInterface来声明的函数，是没有问题的。
LZ实在做不出来，就参考SWFObject的代码吧。

[CaiKanXP]

另外，在页面嵌入flash的时候，需要加上允许脚本访问的属性：
<object><param name="allowScriptAccess" value="sameDomain" /></object>
<embed allowScriptAccess="sameDomain">

如果是跨域加载的flash，sameDomain改成always
<object><param name="allowScriptAccess" value="always" /></object>
<embed allowScriptAccess="always">

[madpc]

同3楼，也就是你要在as中暴露接口给js

[diffmaker]

ExternalInterface.addCallback("doPlay", doPlay);
ExternalInterface.addCallback("doStop", doStop);
ExternalInterface.addCallback("getPlayState", getPlayState);

添加类似的声明

为什么我的还是调不了呢,真是悲剧啊
