Jquery实现Checkbox三级联动
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。
