今天发现，如果你的数据只有一个JsonObject，那么是否直接传JsonObject也可以呢？试试看：

?使用的方法跟JSONArray差不多，只不过使用JsonArray的时候，需要先把每个jsonObject解析出来。所以比较方便的。但是 现在有一个问题，如果你在后台传给的前台Flex中的是一个JSONObject的数据，请问如何在前台解析出来的。就是这里的代码该如何写呢：
public?function showTotalMarkevent:ResultEvent:void{
????????????var marks:Objectdecoderesult?as?text?=?marksname?+?marksmark;?
????????}
这样就可以了，marks.name 和marks.mark就可以分别解析出name和mark。是不是很方便呢。当然如果你的数据很多，就需要用到JSAONArray了。这里就不多讲了。
