Mvc 简繁切换

1.首先引用cookie Jquery

<script type="text/javascript"src="~/script/jquery.cookie.js"></script>

2.JS方法：

 function TraditionalChina(res) {
            $.cookie('IsSimple', res, { expires: 1, path: '/' });
            location.reload();
        }
/*
调用方法：
<a href="javascript:;"onclick="TraditionalChina(false)">简体</a>
<a href="javascript:;"onclick="TraditionalChina(true)">繁體</a>
*/

3.后台切换代码：

using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;
using System.Web;
using System.Web.Mvc;
using System.Web.UI;
using TOOL;
using DAL;
