如何判断SWF文件何时从javascript完成加载？

Question

I need to know when my swf is ready to start playing (eg the initial loader has finished downloading). I know I can use ExternalInterface.call('someJSFunc') in a [loader][1] handler within the swf, but if possible, I'd rather not have that dependency.

Is there better a way just within JS? The only thing I've come up with so far is something like:

// continually check if the flash is ready
var int = setInterval(function(){
    var fl = $('#flashMovie').get(0);
    if (fl) {
        doThings();
        clearInterval(int);
    }
}, 50);

Answer 1

swfobject.embedSWF(swfUrl, id, width, height, version, expressInstallSwfurl, flashvars, params, attributes, callbackFn)

Not sure if this will help you but the last parameter to swfobject is a callback function that gets called when the swf tag is created.

callbackFn (JavaScript function, optional) can be used to define a callback function that is called on both success or failure of creating a Flash plug-in <object> on the page (see API documentation)
