flex复选框和下拉列表的几种用法整理（flex on me）干货分享

下面是页面加载的初始化方法

public function init(event:Event):void{ 

for(var i:int=0;i

if(“数学”==array[i].name){

subject.selectedIndex=i;

checkbox[i].selected=true;

}

}

}

这里我顺便把数学的复选框弄成了默认选中

看起来代码有点乱，下面我把整个页面代码都贴出来

xmlns:s=”library://ns.adobe.com/flex/spark”

xmlns:mx=”library://ns.adobe.com/flex/mx” minWidth=”955″ minHeight=”600″ initialize=”init(event)”>

import mx.controls.Alert;

public var all:String=””;

public var array:Array=new Array();

public function init(event:Event):void{

for(var i:int=0;i

if(“数学”==array[i].name){

subject.selectedIndex=i;

checkbox[i].selected=true;

}

}

}

//全选

private function checkAll():void{

for(var i:int=0;i

checkbox[i].selected=true;

all=all+checkbox[i].data+”,”;

}

Alert.show(“选择了：”+all.substr(0,all.lastIndexOf(“,”)));

all=””;

}

//全不选

private function checkNotAll():void{

for(var i:int=0;i

checkbox[i].selected=false;

}

}

//反选

private function reverse():void{

for(var i:int=0;i

if(checkbox[i].selected){

checkbox[i].selected=false;

}else{

checkbox[i].selected=true;

}

}

}
