今天使用了jquery提供的对json的操作的函数,感觉超级爽哦!下面就把代码贴出
js
 1function getjson()
 2    {
 3      $("[id=ready]").remove();//返回id=ready的所有dom元素
 4
 5      $.ajax(
 6             {
 7                type:"get",
 8                dataType:"json",
 9                url:"jspage.aspx",
10                data:"id=1",
11                success:function(msg)
12                {
13                   var data=msg.bbslist; 
14                  //$("#databox").html(msg);
15                  //cleartext();
16                   $.each(data,function(i,n)
17                               {                                                                                          
18                                  var row=$("#temp").clone();
19                                  row.find("#listtile").text(n.listtile);
20                                  row.find("#listvalue").text(n.listvalue);
21                                  row.attr("id","ready");                                 
22                                  row.appendTo("#mainbox");
23                               }
 
24                  );
25               
26                }

27             }

28            );
29    }
