从Flex 4 Web应用程序调用JavaScript函数 [英] Calling JavaScript function from Flex 4 web application

问题描述

我需要从基于Flash 4的Web应用程序调用JavaScript函数。当我在调试模式下运行它时，它运行完美，但是当我发布版本或在其他机器上运行相同的应用程序，它不会调用JavaScript函数。

测试我只是调用JavaScript的示例Alert函数。有人可以帮我什么我失踪？

 < mx：Application xmlns：mx =http：//www.adobe .com / 2006 / mxml
 layout =verticalinitialize =application1_initializeHandler（event）
 verticalAlign =middle
 backgroundColor =white> 
 
< mx：Script> 
 <！[CDATA [
 import mx.controls.Alert; 
导入mx.events.FlexEvent; 
 public function btnLogin_click（）：void 
 {
 var s：String; 
 if（ExternalInterface.available）
 {
 ExternalInterface.call（alert，Hello World！）; 
} 
 else 
 {
 Alert.show（External interface not available）; 
} 
 trace（s）; 
 
 
 protected function application1_initializeHandler（event：FlexEvent）：void 
 {
 flash.system.Security.allowDomain（always）; 
} 
 
]]> 
< / mx：Script> 
 
< mx：表格> 
< mx：FormItem> 
< mx：Button id =btnLoginlabel =Loginclick =btnLogin_click（）/> 
< / mx：FormItem> 
< / mx：表格> 
 
< / mx：应用程序>那么，首先，确保你的测试机器上有JavaScript代码打开，然后也确保你添加swfobject.js文件后添加你的JavaScript文件/代码。
 
 
我有类似的问题，但它解决了当我移动swfobject .js位于所有js的顶部。
 
I need to call javascript function from Flash 4 based web application. When I run it in Debug mode it runs perfectly but when I make release build or run same application on other machine it does not call JavaScript function.

For testing I am just calling sample Alert function of JavaScript. Can someone help me what I am missing ?
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
    layout="vertical" initialize="application1_initializeHandler(event)"
    verticalAlign="middle"
    backgroundColor="white">

 <mx:Script>
  <![CDATA[
   import mx.controls.Alert;
   import mx.events.FlexEvent;
   public function btnLogin_click():void 
   {
    var s:String;    
    if (ExternalInterface.available) 
    {     
         ExternalInterface.call("alert", "Hello World!"); 
    } 
    else 
    {
     Alert.show("External interface not available");
    }
    trace(s); 
   }

   protected function application1_initializeHandler(event:FlexEvent):void
   {
    flash.system.Security.allowDomain("always");
   }

  ]]>
 </mx:Script>

 <mx:Form>       
  <mx:FormItem>        
   <mx:Button id="btnLogin" label="Login" click="btnLogin_click()" />        
  </mx:FormItem>       
 </mx:Form>

</mx:Application>

解决方案
Well, firstly, make sure JavaScript on your testing machine is turned on and then also make sure you are adding your JavaScript file/code after adding swfobject.js file.

I had similar problem but it worked out when I moved swfobject.js at the top of all js includes.
