httpService AsyncToken和AsyncResponder示例

我不知道你到底在照顾什么,但是 here 或 here 例如,是使用 AsyncToken 和 AsyncResponder

编辑:

1. 你的 dataList 必须是 Bindable
2. 不要设置 数据学家 在每个循环迭代中
3. 你必须调用你的函数 getResults 当你的结果准备好的时候
4. event 在里面 result 函数是一个 Event 而且也是 ResultEvent 哪里有 结果 包含数据的字段

可能看起来像这样(未测试):

[Bindable]
public var dataList:ArrayCollection;

public function getResults(source:String) : ArrayCollection {
    var ac:ArrayCollection = new ArrayCollection();
    var data:Array = source.split('#');
    for (var i:int = 0; i < data.length; i += 3) {  
     ac.addItem( {row: data[i], column: data[i+1], value: data[i+2]} );
    }
    return ac;
}

private function result(event:ResultEvent) : void {
 dataList = getResults( String(event.result) );
}

这是一个使用简单的PHP文件在本地Web服务器上运行数据的工作示例。
