JavaScript如何獲取并且執行flash中flash.external.ExternalInterface.addCallback注冊的函數
測試瀏覽器：IE6,IE7,IE8,Firefox3.6,谷歌chrome 14.0.835.202 m
AS腳本
function loadPicture(){//......代碼......//......代碼......}flash.external.ExternalInterface.addCallback("forJS", null, loadPicture);//注冊JavaScript中調用的回調函數輸出swf到html頁面的JS腳本，swf的ID為swfId
document.write('<div class="dvswf">' + (document.all ? '<object id=swfId classid=clsid:D27CDB6E-AE6D-11cf-96B8-444553540000><param name="src" value="/images/loadSwf.swf"></object>': '<embed id="swfId" type="application/x-shockwave-flash" src="/images/loadSwf.swf"/>') + '</div>');測試代碼如下
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html;charset=gb2312"/></head><body><script type="text/javascript"> document.write('<div class="dvswf">' + (document.all ? '<object id=swfId classid=clsid:D27CDB6E-AE6D-11cf-96B8-444553540000><param name="src" value="/images/loadSwf.swf"></object>': '<embed id="swfId" type="application/x-shockwave-flash" src="/images/loadSwf.swf"/>') + '</div>');</script><script type="text/javascript">function $(Id){return document.getElementById(Id);}function getFlashMethod(swfID) {//獲取 if (window[swfID] && window[swfID].forJS) alert('window')//IE，chrome if (document[swfID] && document[swfID].forJS) alert('document')//IE，Firefox if ($(swfID).forJS) alert('document.getElementById')//IE，Firefox，chrome}</script><input type="button" value="獲取swf容器" onclick="getFlashMethod('swfId')" /><br /></body></html>
通過上面的測試代碼可以知道IE，Firefox，谷歌chrome獲取flash.external.ExternalInterface.addCallback注冊的回調函數容器對象如下
IE：window，document，document.getElementById
Firefox：document，document.getElementById
谷歌chrome：window，document.getElementById
