String to JSON  , JSON to ArrayCollection

==============

import com.adobe.serialization.json.JSON

var rawData:String = String('[{"name":"zhanzhihu","age":22,"gender":"male"},{"name":"zhanzhihu2","age":22,"gender":"male"}]'); 

var ac:ArrayCollection = new ArrayCollection(JSON.decode(rawData) as Array );

注意：String中属性必须带上""，如"name"。
