package {import flash.display.Sprite;
public class w1 extends Sprite{var fruits:Array=["a","b","c","d","e"];var Administrator:String= fruits[Math.floor(Math.random()*fruits.length)];trace("为" +Administrator);switch(Administrator){ case "a": trace("为a"); break; case "b": trace("为b"); break; case "c": trace("为c"); break; case "d": trace("为d"); break; case "e": trace("为e"); break; default: trace("呵呵"+Administrator); }}}


提示为我没定义Administrator这个属性 可是 var Administrator:String是干了什么

额，弱弱的说下，你定义了类为什么不定义构造函数呢，public function w1(){}

哈哈，已经发现了
