AS3 navigateToURL导致ExternalInterface 执行失败问题 我们先看下面代码：<?xml version="1.0" encoding="utf-8"?> <mx:application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <!--[CDATA[ import flash.external.ExternalInterface; private function init1():void { var url:String = "javascript:alert('执行navigateToURL');"; var request:URLRequest = new URLRequest(url); navigateToURL(request,"_self"); } private function init2():void { ExternalInterface.call("function function1(){alert('执行ExternalInterface');}"); } private function clickfun():void { ExternalInterface.call("function function2(){window.document.title = '更改后的标题';}"); } ]]--> </mx:Script> <mx:Button x="150" y="92" label="1" click="init1()"/> <mx:Button x="544" y="92" label="2" click="init2()"/> <mx:Button x="404" y="315" label="更改标题" click="clickfun()"/> </mx:Application> <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <!--[CDATA[ import flash.external.ExternalInterface; private function init1():void { var url:String = "javascript:alert('执行navigateToURL');"; var request:URLRequest = new URLRequest(url); navigateToURL(request,"_self"); } private function init2():void { ExternalInterface.call("function function1(){alert('执行ExternalInterface');}"); } private function clickfun():void { ExternalInterface.call("function function2(){window.document.title = '更改后的标题';}"); } ]]--> </mx:Script> <mx:Button x="150" y="92" label="1" click="init1()"/> <mx:Button x="544" y="92" label="2" click="init2()"/> <mx:Button x="404" y="315" label="更改标题" click="clickfun()"/> </mx:Application> 函数init1和init2都是通过javascript弹出提示框，clickfun()为修改网页标题。 3个函数单独执行都是成功的，但当 1.先执行init1函数后再调用clickfun函数，会发现clickfun执行失败。 2.先执行init2函数后再调用clickfun函数，会发现clickfun执行成功。 难道是navigateToURL会导致ExternalInterface 执行失败？？请知道原因的朋友指导下。 |
