我从我的一位朋友那里获取了这段代码，但实际上它完全是一团糟，我通过运行此代码得到了很多错误，我有一些问题
现在你会告诉我其他方法很容易解决问题，但我的整个项目只是在这个方法上
提前感谢您的帮助 我试图从过去15天解决这个问题，没有成功，请帮我下面是代码

抛出此代码。此代码由mxmlc编译器从MXML类自动生成，不能在生产中使用。它适用于计算机，而不适用于人类。自己编写正确的代码。我希望它更清晰，更易于维护。是的，这段代码不是由你的朋友写的：）
答案 1 :(得分：0)
此文件是从.mxml文件反编译的，该文件使用标记来描述布局。但是，有些反编译器无法完全转换它，你会看到这样的文件。
如您所见，UIComponentDescriptor的参数是一个对象，它包含许多键 - 值对。它有一些键：
type：类 - ＆gt;这是此组件的类型，它是.mxml文件的节点标记id：字符串 - ＆gt;这是节点的ID，也是您可以在<fx:Script> tag event：对象 - ＆gt;组件将触发的事件stylesFactory：功能 - ＆gt;组件的样式设置propertiesFactory：功能 - ＆gt;包含一些属性和子节点<mx:Canvas id="mainCanvas" borderStyle="none" label="main">
<mx:Button click="onClick(event)" />
</mx:Canvas>
将转换为：
new UIComponentDescriptor({
"type":Canvas,
"id":mainCanvas,
"styleFactory":function():void {
this.borderStyle="none";
},
"propertiesFactory":function():Object {
return({
"label":"main"
"childDescriptors":[new UIComponentDescriptor({
// button's code in here
});
]
})
}
})
对于那些事件：
由于您可以在mxml标记中编写click事件，例如btnOnClick()和btnOnClick(event)，编译器需要执行某些操作以确保事件处理程序接受正确的参数。所以，对于我刚才提到的Button标签，
与键"event"对应的值将如下所示：{"click":"__on_click"}。然后编译器将创建一个新的函数调用__on_click，它可能是这样的：
public function __on_click(event:MouseEvent):void {
onClick(event);
}
显然，在将UIComponentDescriptor转换为.mxml后，您应该替换事件函数。
对于构造函数：
.mxml文件不能有构造函数，但编译器会在.as文件中创建一个包含UIComponentDescriptor的文件。构造函数也会为它的变量做一些初始化。转换为.mxml文件时，需要在变量声明后进行初始化。
例如：
public function MyCanvas(){
this._documentDescriptor_ = new UIComponentDescriptor({
//……
});
this.myArray = new Array();
}
你应该把它转换成这个：
<fx:Script><![CDATA[
var myArray:Array = new Array();
]]></fx:Script>
因此，最重要的工作是将UIComponentDescriptor转换为.mxml标记。这是一个简单的python脚本，可以帮助你做到这一点：
