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
js
1
function 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
