初识ActionScript

    <fx:Declarations>
        <!-- 将非可视元素（例如服务、值对象）放在此处 -->

    <fx:Script>   
        <![CDATA[
            //初始化
            internal function initApp():void{
            var arr:Array = new Array();
            //给数组添加元素
        for(var i:Number =0 ;i<6;i++){
            arr.push("元素"+i);
        }
        //list控件指定数据

        }
        ]]>

ActionScript循环控制

                var i:int = 0;
                do{

continue、break以及函数的用法都与C语言类似

    <s:layout>
        <s:BasicLayout/>

    <fx:Declarations>
        <!-- 将非可视元素（例如服务、值对象）放在此处 -->
    </fx:Declarations>
    <fx:Script>

                        continue;

    </fx:Script>
    <mx:TextArea x="97" y="52" width="469" height="253" id="txt" fontSize="12" fontFamily="微软雅黑" editable="true"/>
