flex 动态给控件赋值,通过反射遍历MXML中的组件。当有100个mx:TextInput 需要给他们text属性赋值的时候，如果id存在规律可以用for,但如果id完全没规律的话那麽就需要用下面方法了，通过反射

var instanceInfo:XML=describeType(this);//通过反射机制取出当前MXML中的信息

trace(instanceInfo..accessor.(@type=="mx.controls::TextInput"));
for each(var propertyInfo:XML in properties){
  var propertyName:String =propertyInfo.@name;//此处取出的为textinput的id
  TextInput(this[propertyName]).text="1111";
