Question

我创建了一个新的Flex项目，并在.mxml文件中包含以下代码。

<?xml version="1.0"?>
<!-- usingas/StatementSyntax.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="doSomething()">
    <mx:Script><![CDATA[
        var airSWF:Object; // This will be the reference to the main class of air.swf
        var airSWFLoader:Loader = new Loader(); // Used to load the SWF
        var loaderContext:LoaderContext = new LoaderContext(); 
        // Used to set the application domain domain

        loaderContext.applicationDomain = ApplicationDomain.currentDomain;

        airSWFLoader.contentLoaderInfo.addEventListener(Event.INIT, onInit);
        airSWFLoader.load(new URLRequest("http://airdownload.adobe.com/air/browserapi/air.swf"), 
            loaderContext);

        function onInit(e:Event):void 
        {
            airSWF = e.target.content;
        }
    ]]></mx:Script>

    <mx:Label id="label1"/>

</mx:Application>

这些是错误：

1120：访问未定义的属性airSWFLoader。 WebTry.mxml / WebTry / src第12行Flex问题

1120：访问未定义的属性loaderContext。 WebTry.mxml / WebTry / src第10行Flex问题

我们的想法是能够让air.swf文件在上面的代码中运行，以检测我们的航空应用程序是否已安装，从浏览器启动航空应用程序等。

好吧，没有人回答，但这是解决方案！

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

                           creationComplete="init()" >

                                var loaderContext:LoaderContext = new LoaderContext();
                                loaderContext.applicationDomain = ApplicationDomain.currentDomain;

                          click="onButtonClicked(event)" enabled="false"/>
