使用弹出窗体修改数据,之后返回值

 

初次使用Flex,希望在程序中能使用弹出窗口的类型,就是有A、B两个窗体,B从A中弹出,并显示A中的指定数据且可修改,修改完成后的数据更新到A中:

A窗体:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    
<mx:Script>
        
<![CDATA[
            
import mx.managers.PopUpManager;
            
private var _win1:win1 = new win1();
            
private function showWin1():void{
                _win1.s_tmp 
= this.p_txt.text;
                PopUpManager.addPopUp(_win1, 
thistrue);
                PopUpManager.centerPopUp(_win1);
                _win1.addEventListener(
"t1", update);
            }
            
private function update(evt:Event):void{
                
this.p_txt.text = _win1.s_tmp;
                PopUpManager.removePopUp(_win1);
            }
        ]]
>
    
</mx:Script>
    
<mx:TextInput x="333" y="129" id="p_txt"/>
    
<mx:Button x="380" y="159" label="Button" click="showWin1();"/>
    
</mx:Application>

 

B窗体:

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="400" height="300">
    
<mx:Script>
        
<![CDATA[
            
import mx.managers.PopUpManager;
            [Bindable]
            
public var s_tmp:String;
            
            
private function click_return():void{
                s_tmp 
= this.c_txt.text;        //必须,绑定只是在此值改变的时候在Text中更新,但Text更新时绑定变量的值却不会自动改变
                dispatchEvent(new Event("t1"));    //手动触发事件
            }
        ]]
>
    
</mx:Script>
    
<mx:TextInput x="110" y="82" id="c_txt" text="{s_tmp}"/>
    
<mx:Button x="157" y="112" label="Button" click="click_return();"/>
</mx:TitleWindow>
