我有一个我正在使用flex的应用程序,当按下单击按钮时,我想将按钮的文本更改为xml中的随机条目.... xml位于assets文件夹中并标题为games.xml。我希望在按下按钮时选择一个随机游戏。
这里是games.xml
<games>
<game> GameName1
<description> description1 </description>
</game>
<game> GameName2
<description> description2 </description>
</game>
<game> GameName3
<description> description3 </description>
</game>
</games>
这是flex文件
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
backgroundColor="#0000FF" title="games!">
<fx:Script>
<![CDATA[
protected function button1_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub
gamebutton.label="test" <---i want this to be a random game name
}
]]>
</fx:Script>
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<s:Button id="gamebutton" click="button1_clickHandler(event)" horizontalCenter="0" top="10" x="0" width="95%" label="Pick A Game"/>
</s:View>
感谢您提供的任何帮助!
答案 0 :(得分:1)
您只需将以下代码放入button1_clickHandler
即可protected function button1_clickHandler(event:MouseEvent):void
{
var num:int = (Math.random() * (4 - 1)) + 1
// TODO Auto-generated method stub
gamebutton.label="GameName" + num.toString();
}
这里4是最大游戏+ 1,1是munimum.and num是1到3之间的随机数。
度过愉快的一天。
