一、测试的数据（JSON格式，用存储过程生成的）

[{"count":16,"list":[{"MenuID":3,"MenuName":"信息管理","MenuCode":"msg","MenuCount":2,"MenuList":[{"MenuID":4,"MenuName":"信息发布","MenuCode":"msg_publis"},{"MenuID":5,"MenuName":"信息列表","MenuCode":"msg_list"}]},{"MenuID":6,"MenuName":"会员管理","MenuCode":"user","MenuCount":1,"MenuList":[{"MenuID":7,"MenuName":"会员列表","MenuCode":"user_list"}]},{"MenuID":8,"MenuName":"积分管理","MenuCode":"jf","MenuCount":1,"MenuList":[{"MenuID":9,"MenuName":"积分类别","MenuCode":"jf_type"}]},{"MenuID":10,"MenuName":"发布管理","MenuCode":"ps","MenuCount":1,"MenuList":[{"MenuID":11,"MenuName":"标签管理","MenuCode":"ps_lable"}]},{"MenuID":13,"MenuName":"管理员管理","MenuCode":"admin","MenuCount":4,"MenuList":[{"MenuID":14,"MenuName":"管理员组","MenuCode":"admin_gp"},{"MenuID":15,"MenuName":"权限管理","MenuCode":"admin_rule"},{"MenuID":43,"MenuName":"管理员列表","MenuCode":"admin_list"},{"MenuID":45,"MenuName":"部门管理","MenuCode":"admin_bm"}]},{"MenuID":16,"MenuName":"商品管理","MenuCode":"sp","MenuCount":2,"MenuList":[{"MenuID":26,"MenuName":"商品列表","MenuCode":"sp_list"},{"MenuID":27,"MenuName":"商品类别","MenuCode":"sp_type"}]},{"MenuID":17,"MenuName":"活动管理","MenuCode":"hd","MenuCount":1,"MenuList":[{"MenuID":28,"MenuName":"活动列表","MenuCode":"hd_list"}]},{"MenuID":18,"MenuName":"支付管理","MenuCode":"pay","MenuCount":1,"MenuList":[{"MenuID":29,"MenuName":"支付接口管理","MenuCode":"pay_api"}]},{"MenuID":19,"MenuName":"短信管理","MenuCode":"sms","MenuCount":2,"MenuList":[{"MenuID":30,"MenuName":"短信发送","MenuCode":"sms_send"},{"MenuID":31,"MenuName":"短信列表","MenuCode":"sms_list"}]},{"MenuID":20,"MenuName":"代金券管理","MenuCode":"djq","MenuCount":2,"MenuList":[{"MenuID":32,"MenuName":"代金券发放","MenuCode":"djq_send"},{"MenuID":33,"MenuName":"代金券列表","MenuCode":"djq_list"}]},{"MenuID":21,"MenuName":"优惠券管理","MenuCode":"yhq","MenuCount":2,"MenuList":[{"MenuID":34,"MenuName":"优惠券发放","MenuCode":"yhq_send"},{"MenuID":35,"MenuName":"优惠券列表","MenuCode":"yhq_list"}]},{"MenuID":22,"MenuName":"现金券管理","MenuCode":"xjq","MenuCount":2,"MenuList":[{"MenuID":36,"MenuName":"现金券发放","MenuCode":"xjq_send"},{"MenuID":37,"MenuName":"现金券列表","MenuCode":"xjq_list"}]},{"MenuID":23,"MenuName":"物流管理","MenuCode":"wl","MenuCount":1,"MenuList":[{"MenuID":38,"MenuName":"物流公司管理","MenuCode":"wl_cmp"}]},{"MenuID":24,"MenuName":"订单管理","MenuCode":"order","MenuCount":1,"MenuList":[{"MenuID":39,"MenuName":"订单列表","MenuCode":"order_list"}]},{"MenuID":25,"MenuName":"店铺管理","MenuCode":"shop","MenuCount":1,"MenuList":[{"MenuID":40,"MenuName":"店铺列表","MenuCode":"shop_list"}]},{"MenuID":51,"MenuName":"网站设置","MenuCode":"site","MenuCount":2,"MenuList":[{"MenuID":42,"MenuName":"后台菜单管理","MenuCode":"site_menu"},{"MenuID":49,"MenuName":"网站信息设置","MenuCode":"site_cfg"}]}]}]

二、ASPX页面代码

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="AdminRules.aspx.cs" Inherits="Manager_Admins_AdminRules" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">    <title>权限管理</title>    <script type="text/javascript" src="../../Scripts/Jquery/jquery-1.6.2.js"></script>    <script type="text/javascript" src="js/AdminRules.js"></script>    <style type="text/css">        ul        {            list-style: none;            text-align: left;        }    </style></head><body>    <form id="form1" runat="server">    <div id="div_info">    </div>    <div id="div_content">    </div>    <div>        <input type="button" id="btn_save" value="保存" onclick="GetRules()" />        <input type="hidden" id="h_Rules" />    </div>    </form></body></html>

三、AdminRules.js代码

$(document).ready(function (e){    var dd;    $.ajax({        type: "POST",        data: "g_cmd=get",        url: "Ashx/AdminRules.ashx",        contentType: "application/x-www-form-urlencoded; charset=utf-8",        dataType: "text",        success: function (text)        {            CreteHtml(text);        },        error: function (request, message, ex)        {            alert("错误：" + message);        }    });})//动态创建checkbox集合function CreteHtml(json){    var dataObj = eval(json);    var table = $("<table id='tb_content' border='1'><tr><td> </td><td>功能名称</td><td>权限选项</td></tr>");    table.appendTo($("#div_content"));    $.each(dataObj[0].list, function (idx, item)    {        var tr = $("<tr></tr>");        var tdcbox = $("<td></td>");        var td = $("<td>" + item.MenuName + "</td>");        var cb = $("<input type='checkbox' id='" + item.MenuCode + "' onclick='CheckAll(this.id)' />");        cb.appendTo(tdcbox);        tdcbox.appendTo(tr);        td.appendTo(tr);        tr.appendTo(table);        td = $("<td></td>");        var menus = item.MenuList;        $.each(menus, function (idx1, item1)        {            var ul = $("<ul></ul>");            var li_ruls = $("<li><input type='checkbox' id='" + item1.MenuCode + "_mody' onclick='CheckParent(this.id)' />修改<input type='checkbox' id='" + item1.MenuCode + "_add' onclick='CheckParent(this.id)' />增加<input type='checkbox' id='" + item1.MenuCode + "_del' onclick='CheckParent(this.id)' />删除</li>");            var li = $("<li><input type='checkbox' id='" + item1.MenuCode + "' onclick='CheckParent(this.id)' />" + item1.MenuName + "</li>");            li.appendTo(ul);            li_ruls.appendTo(ul);            ul.appendTo(td);            td.appendTo(tr);            tr.appendTo(table);        });    });    $("#div_content").append("</table>");}//全选全不全功能function CheckAll(id){    if ($("input[type=checkbox][id='" + id + "']").is(":checked"))    {        $("input[type=checkbox][id^='" + id + "']").attr("checked", true);//当前ID开头的checkbox全选    }    else    {        $("input[type=checkbox][id^='" + id + "']").attr("checked", false); //当前ID开头的checkbox全不选    }}//checkbox联动function CheckParent(id){    CheckAll(id);//先进行是否全选的操作    var s_ParentID = id.substring(0, id.indexOf('_'));//取得一级checkbox的id    var s_tmp = id.substring(id.indexOf('_') + 1, id.length);    s_tmp = s_tmp.substring(0, s_tmp.indexOf('_'));    var s_ParentID_ID = s_ParentID + "_" + s_tmp;//取得二级checkbox的id    var tf = false;//一级checkbox是否全选    var tf1 = false;//二级checkbox是否全选    if (!s_tmp == "")//为空的话说明是点击的二级checkbox，不用判断三级checkbox的状态    {        if (!$("input[type=checkbox][id='" + s_ParentID_ID + "']").is(":checked"))        {            $("input[type=checkbox][id='" + s_ParentID_ID + "']").attr("checked", true);//如果三级checkbox有选中的情况，二级的checkbox也会选中        }        else        {            l = $("input[type=checkbox][id^='" + s_ParentID_ID + "']");//获取三级checkbox的集合            $.each(l, function (idx, item)//循环            {                if (s_ParentID_ID != $(item)[0].id)//不判断自己(二级checkbox)                {                    if ($("input[type=checkbox][id='" + $(item)[0].id + "']").is(":checked"))                    {                        tf1 = true;//如果三级checkbox有选中的直接赋值为true并退出each                        return false;                    }                }            })            $("input[type=checkbox][id='" + s_ParentID_ID + "']").attr("checked", tf1);//更新二级checkbox的选中状态        }    }    if (!$("input[type=checkbox][id='" + s_ParentID + "']").is(":checked"))    {        $("input[type=checkbox][id='" + s_ParentID + "']").attr("checked", true); //如果二级checkbox有选中的情况，一级的checkbox也会选中    }    else    {        var l = $("input[type=checkbox][id^='" + s_ParentID + "']"); //获取二级checkbox的集合        $.each(l, function (idx, item)//循环        {            if (s_ParentID != $(item)[0].id)//不判断自己(一级checkbox)            {                if ($("input[type=checkbox][id='" + $(item)[0].id + "']").is(":checked"))                {                    tf = true; //如果二级checkbox有选中的直接赋值为true并退出each                    return false;                }            }        })        $("input[type=checkbox][id='" + s_ParentID + "']").attr("checked", tf); //更新一级checkbox的选中状态    }}

四、AdminRules.ashx代码直接context.Response.Write第一条的字符串即可。
