在Flex中使用JSON

要把一个字符串传到Flex前台~ 已经写好，结果又需要传多一个，不想改太多~
正好闲来无事，就想用用Json~

其实也很简单，就改一点点~(仅示改动地方)

...
import com.adobe.serialization.json.JSON;
...

private function someHandle():void {
  //get the raw JSON data and cast to String  
  var rawData:String = String(event.result);  
  
  //decode the data to ActionScript using the JSON API  
  //in this case, the JSON data is a serialize Array of Objects.  
  var arr:Array = (JSON.decode(rawData) as Array);  
  
  //create a new ArrayCollection passing the de-serialized Array  
  //ArrayCollections work better as DataProviders, as they can  
  //be watched for changes.  
  var dp:ArrayCollection = new ArrayCollection(arr);  
  
  //pass the ArrayCollection to the DataGrid as its dataProvider.  
  grid.dataProvider = dp;  
}

一般情况下会没有包含com.adobe.serialization这个包的包，我给附上了~

就这么简单，然后在后台里修改相应返回值为Json格式就行了~

网站输入法有很多地方无法切换，只需到浏览器其它位置点一下，再点回来就可以输入了.
