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![](https://www.cnblogs.com/Images/OutliningIndicators/InBlock.gif)
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
}
