ActionScript中的循环

1.do..whlie

<mx:Script><![CDATA[internal function initApp():void {// 保存1+2+..+100的值var sum:int = 0;var i:int = 0;do {sum = sum + i;i++;}while (i <= 100);// 在安装了flash player debugger时，使用trace()在控制台输出打印信息。txt.text = "1+2+..+100=" + sum;trace("1+2+..+100="+sum);}]]></mx:Script>

2.for

for (var j:int=0;j<=100;j++) {     sum += j;    }    txt.text = "\n" + "1+2+..+100=" + sum;

3.for.. in

var student:Object = new Object();student.id = "1001";student.name = "张三";student.age =  20;//遍历student对象的所有属性，并取出属性和值。// prop:属性名，student[prop]:属性值。for (var prop:String in student) {txt.text += "\n" + prop + ":" + student[prop];}

4.for each..in

// 遍历student的所有属性，并取出属性值。// *表示任何类型。value:student的属性值。for each(var value:* in student) {txt.text += "\n" + value;}
