3.循环输出
对json用点，可以通过json树转为树形后，在根据显示的树形节点图层级关系通过点来实现！！！

特别注意：

$(document).ready(function() {
  // Handler for .ready() called.
});

后面是： }); ，这个是函数的},ready的),函数在ready里面，所以：});,分号也别忘记了。


Js转字符串示例：



Flash转盘Ajax调用后对返回串转为Json类：

直接用Jquery返回时就已经让Jquery帮忙转为了Json的代码，注意给Flash用时需要有一个全局变量，在success里面把返回的data这个Json对象给jsonObject后，在Success函数外面进行return jsonObject ,如下：
