多级JSON的读取

Question

Answer 1

你这关键在于解析json数据嘛，解析方法很多。可以用extjs来解析json数据，你可以试试。
假如你上面的数据为data
那么：
var json = eval("(" + data+ ")");
alert(json.results);//这里弹出的应该就是你的数据啦！results下面的子项也可以用.来进行导航获得。我没有测试，但应该是可以的。我作回调时一直是这样解析的。你试一下吧！ps:前提是你要导入extjs的框架文件噢！

Answer 2

有在线解析json的  如果你是要内容的花

Answer 7

说明一下环境，.netframework1.0，要求用asp.net从后台读取！！，谢谢！！

Answer 8

var json = eval("(" + data+ ")");//转化为对象
json.total //1526
//循环读取result中的数据
for(var i=0;i<json.reuslt.length;i++){
      for(var j in json.result[i]){
         alert(j+""+json.result[i][j]); 
     }
}

Answer 10

很明显递归问题。不解释。
假设JSON有1000层深。秒杀上面几层楼。
