JavaScript控制flash操作（兼容IE与FF）

来源：程序员人生发布时间：2013-10-25 13:58:10 阅读次数：2289次

今天开发富媒体广告遇到的问题用JS控制flash 只在IE平台下有效费尽周折才找到兼容的解决方案
方法如下：

重点在于 object的id属性和 EMBED 的name属性 swliveconnect=”true” 属性

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="" id="myFlashMovie" width=481 height=86> <param name=movie value="flips2.swf"> <embed play=false swliveconnect="true" name="myFlashMovie" src="flips2.swf" quality=high bgcolor=#FFFFFF width=481 height=86 type="application/x-shockwave-flash" ....> </embed > </object >

通过js获取flash对象的方法兼容表如下

通过上图得到JavaScript方法来获取flash对象兼容多浏览器

function getFlashMovieObject(movieName)
{
if (window.document[movieName])
{
return window.document[movieName];
}
if (navigator.appName.indexOf("Microsoft Internet")==-1)
{
if (document.embeds && document.embeds[movieName])
return document.embeds[movieName];
}
else // if (navigator.appName.indexOf("Microsoft Internet")!=-1)
{
return document.getElementById(movieName);
}
}

获取到flash对象可以利用相关方法进行操作

播放：: Play()
停止: StopPlay()
停止并回到首帧: Rewind()
下一帧: TGetProperty(nameOfTargetMovieClip, propertyIndex) and GotoFrame(frameNum)
方大或缩小: Zoom(relative percentage)
发送数据: SetVariable(variableName, variableValue)
读取数据: GetVariable(variableName)
