JQuery返回Json的Ajax例子

前台HTML代码：

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
    <script language="javascript" type="text/javascript">
        $(document).ready(function () {
            $("#BtnJson").click(function () {
                //alert(\'testjson\');
                AjaxJsonTest();
            }
            );
        }
        );

        function AjaxJsonTest() {
            $.ajax({
                type: \'post\',
                url: \'Ajax/JsonTest.ashx\',
                dataType: \'json\',
                success: function (data) {
                    var str = \'<table border=1 style=" width:400px;">\';
                    str += \'<tr style="font-weight:bold"><td>name</td><td>age</td><td>sex</td></tr>\';
                    for (var i = 0; i < data.length; i++) {
                        //alert(\'name:\' + data[i].name + \' age:\' + data[i].age + \' sex:\' + data[i].sex);
                        //str += \'<tr><td style="font-weight:bold">name</td><td>\' + data[i].name + \'</td><td style="font-weight:bold">age</td><td>\' + data[i].age + \'</td><td  style="font-weight:bold">sex</td><td>\' + data[i].sex + \'</td></tr>\';
                        str += \'<tr>\';
                        for (var key in data[i]) {
                            str += \'<td>\' + data[i][key] + \'</td>\';
                        }
                        str += \'</tr>\';
                    }
                    str += \'</table>\';
                    $("#divjson").html(str);
                },
                error: function () {
                    alert(\'系统繁忙，请稍候再试！\');
                }
            }
                );            //end ajax
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div id="divjson">

    </div>
    </form>
    <p>
        <input id="BtnJson" type="button" value="JsonTest" /></p>
</body>
</html>

后台的ASHX代码：

using System;
using System.Web;
using System.Text;

public class JsonTest : IHttpHandler {

    public void ProcessRequest (HttpContext context) {
        StringBuilder sb = new StringBuilder();
        context.Response.ContentType = "text/plain";
        sb.Append("[");
        sb.Append("{\"name\":\"cycle\",\"age\":\"28\",\"sex\":\"男\"},");
        sb.Append("{\"name\":\"ring\",\"age\":\"27\",\"sex\":\"男\"},");
        sb.Append("{\"name\":\"jingjing\",\"age\":\"22\",\"sex\":\"女\"}");
        sb.Append("]");
        context .Response .Write (sb.ToString ());
        context.Response.Flush();
        context.Response.End();
    }

    public bool IsReusable {
        get {
            return false;
        }
    }

}
