test.aspx
代码
<script src="js/jquery.js" type="text/javascript" language="javascript"></script> <script type="text/javascript"> $(function(){ $.getjson("handler.ashx",function(json){ $.each(json.data,function(i){$('#content').append("姓名："+json.data[i].name+"----性别："+json.data[i].avg+"----时间："+json.data[i].year+"<br/>");}); }); }); </script> <body> <form id="form1" runat="server"> <p id="content"></p> </form> </body>
把handler.ashx文件内容放入普通aspx文件page_load方法中同样适用
即$.getjson(ssss.aspxfunction(e){});
以上就是jquery $.getjson 与.net 结合用法推荐的详细内容。
