JS how to determine whether the Flash SWF file loaded _javascript tips

JS how to determine if Flash is finished loading it?

How do we recall a JS function we set when the Flash is loaded?

This question, has been bothering me for a long time, until today, consulted a very cow B character, suddenly came to feel!

Oh, maybe, this problem is not a problem to you, but for me, it is a problem, because I always do not know how to determine whether the SWF file is finished loading?

It used to be all about img.onload and so on.

Well, in the end, how can we tell if a flash is finished loading?

Yes, polling, and then determine if a Flash method is working correctly?

Examples are as follows (pseudo code):

(function () { 
var flash = A Flash object on a Web page. 

var interval = setinterval (function () { 
try { 
if (Flash). IsPlaying ()) {//a method to poll flash 
callBack && callback.call (Flash, args);//callback function 
Clearinterval ( interval); 
} 
catch (ex) { 

} 
}, 1000); 

var callBack = function () { 
alert (' Loaded '); 
} 
}) ();

In particular, when Flash is put into a setinterval or settimeout function closure, flash can be caused by JavaScript single-threaded problems that could not be invoked on flash, such as isplaying Player function or the result of the call is not the case, there is a temporary solution, we can read in the polling function to read the Totalframes properties of the flash, read to get, we can think that the flash has been fully loaded into the page!!!

Tested, it works, but there may be a 1-2-second delay.

There's something wrong, welcome to Errata!!!!!!!!! //////////////
