我的UserInfromation表单包含两个输入字段username,location(city)和一个单选按钮作为性别,两个按钮添加和重置。当我点击添加按钮时,数据将在运行时添加到datagrid中。 我无法重现我将如何做到这一点。 有没有人可以用这个例子来帮助我?

以下是一个示例应用(带代码):
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<s:layout>
<s:VerticalLayout/>
</s:layout>
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
private var ac:ArrayCollection = new ArrayCollection();
protected function addBtn_clickHandler(event:MouseEvent):void
{
var obj:Object = new Object();
obj.userName = userNameTI.text;
obj.location = locationTI.text;
ac.addItem(obj);
}
]]>
</fx:Script>
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<mx:Form width="100%">
<mx:FormItem label="UserName:">
<s:TextInput id="userNameTI"/>
</mx:FormItem>
<mx:FormItem label="Location:">
<s:TextInput id="locationTI"/>
</mx:FormItem>
</mx:Form>
<s:Button id="addBtn" label="Add" click="addBtn_clickHandler(event)"/>
<mx:DataGrid id="dg" width="100%" dataProvider="{ac}"/>
</s:WindowedApplication>
作为一项练习,有几件事情留给你:)
