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
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
}
24 );
25
26 }
27 }
28 );
29
}

23 {
24 StringBuilder jsonBuilder = new StringBuilder();
25 jsonBuilder.Append("{\"");
26 jsonBuilder.Append(dt.TableName.ToString());
27 jsonBuilder.Append("\":[");
28 for (int i = 0; i < dt.Rows.Count; i++)
29 {
30 jsonBuilder.Append("{");
31 for (int j = 0; j < dt.Columns.Count; j++)
32 {
33 jsonBuilder.Append("\"");
34 jsonBuilder.Append(dt.Columns[j].ColumnName);
35 jsonBuilder.Append("\":\"");
36 jsonBuilder.Append(dt.Rows[i][j].ToString());
37 jsonBuilder.Append("\",");
38 }
39 jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
40 jsonBuilder.Append("},");
41 }
42 jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
43 jsonBuilder.Append("]");
44 jsonBuilder.Append("}");
45 return jsonBuilder.ToString();
46 }
47}

这就是主要的代码了，相信各位都会组合吧，我就不再多介绍了，大家体会一下哈！
