我这么写为什么不执行呢？哪错了呢？

HTML code

    <div class="compile_hull" id="divKey">                 <img src="../images/loading.gif" vspace="40" />                    </div>

JScript code

    var key = function (id) {            $.ajax({                type: "POST",                url: '../rAjax/load_key.ashx',                data: { id: id },                success: function (msg) {                    $("#divKey").html(msg);                }            });        };

C# code

<%@ WebHandler Language="C#" Class="load_key" %>using System;using System.Web;public class load_key : IHttpHandler {        public void ProcessRequest (HttpContext context) {        context.Request.ContentEncoding = System.Text.Encoding.UTF8;        string pid = context.Request["id"];        context.Response.ContentEncoding = System.Text.Encoding.UTF8;        context.Response.Charset = "utf-8";        context.Response.ContentType = "text/plain";        context.Response.Write(test(pid));    }    public bool IsReusable {        get {            return false;        }    }    public string test(string id)    {        return "hahahahahah" + id;    }}

JScript code

$(function(){            $.ajax({                type: "POST",                url: '../rAjax/load_key.ashx',                data: { id: "id" },                success: function (msg) {                    $("#divKey").html(msg);                }            });        });
[解决办法]
仓老师.... jquery 的ajax请求可以不写请求类型，但是一定要写返回类型
JScript code
$(function(){            $.ajax({                type: "POST",                dataType: "json",                url: '../rAjax/load_key.ashx',                data: { id: "id" },                success: function (msg) {                    $("#divKey").html(msg);                }            });        });
