Flex中利用StringUtil类的trimArrayElements函数进行空格处理的例子
By Minidxer | August 24, 2008
和前面Flex中空格处理函数StringUtil类trim()方法用法的例子类似的，接下来的例子演示了Flex中如何利用StringUtil类的trimArrayElements函数，进行空格处理。
让我们先来看一下Demo（可以右键View Source或点击这里察看源代码）：
下面是完整代码(或点击这里察看)：
Download: main.mxml
- <?xml version="1.0" encoding="utf-8"?>
- <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
- layout="horizontal"
- verticalAlign="middle"
- backgroundColor="white"
- creationComplete="init()">
- <mx:Script>
- <![CDATA[
- import mx.utils.StringUtil;
- private function init():void {
- var arrayStr:String = arrayToList(arr);
- arrayStr = StringUtil.trimArrayElements(arrayStr, ",");
- list2.dataProvider = listToArray(arrayStr);
- }
- private function listToArray(value:String, delimiter:String = ","):Array {
- return value.split(delimiter);
- }
- private function arrayToList(value:Array, delimiter:String = ","):String {
- return value.join(delimiter);
- }
- private function addSingleQuotes(item:Object):String {
- return "'" + item.toString() + "'";
- }
- ]]>
- </mx:Script>
- <mx:Array id="arr">
- <mx:String> The </mx:String>
- <mx:String> quick </mx:String>
- <mx:String>
- brown
- </mx:String>
- <mx:String> fox </mx:String>
- </mx:Array>
- <mx:List id="list1"
- dataProvider="{arr}"
- variableRowHeight="true"
- labelFunction="addSingleQuotes" />
- <mx:List id="list2"
- variableRowHeight="true"
- labelFunction="addSingleQuotes" />
- </mx:Application>
