javascript与actionscript(flash)交互

html中插入flash

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="550" height="400" id="myswf" align="center">
        <param name="allowScriptAccess" value="always" />
        <param name="movie" value="Test.swf" />
        <param name="quality" value="high" />
        <param name="bgcolor" value="#ffffff" />
        <embed src="Test.swf" quality="high" bgcolor="#ffffff" width="550" height="400" name="myswf" align="center" allowScriptAccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
    </object>

javascript获取[flash object]引用

function getSWF() {
    var flash;
    if (navigator.appName.indexOf("Microsoft") != -1) {
        flash = document.getElementById("myswf");
    } else {
        flash = window.document["myswf"];
    }
}

actionscript中的定义

if(ExternalInterface.available){
    ExternalInterface.call("jsFn", "aa");
    ExternalInterface.addCallback("init", init);
}
