This article will explain in detail how to achieve communication between AS3 and JS. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Running environment: you need to install IIS and create a website directory

The communication method between AS3 and external container is relatively simple:

Import flash.text.TextField;var txt:TextField = new TextField (); this.addChild (txt); txt.text = "wait..."; / / register the method with JS. When JS calls the as3Function method, it executes the callback method ExternalInterface.addCallback ("as3Function", callback); function callback ($param:String): void {txt.text = $param;} / / directly calls SJ's method getReadyExternalInterface.call ("getReady")

Note: first call ExternalInterface.addCallback, then call ExternalInterface.call

JS Code:

FLASH interacts with JS var jsReady = false; function pageInit () {jsReady = true } / * * if false,flash is returned if the page is not loaded, this method needs to be called again * / function getReady () {if (jsReady) {/ / as3Function method is the flash registered method getSwfInstance ("FlashID") .as3Function ("success") } else {return jsReady }} / * * get flash. Note here: the element name attribute is obtained according to * / function getSwfInstance (name) {if (navigator.appName.indexOf ("Microsoft")! =-1) {return window [name] } else {return document [name];}}

Note: there are many ways to embed swf files into html, especially the key thing is to get the embedded swf object, through the code you can find that access to swf object is through the name property in embed.
