ASP.Net MVC4中封装CSS和js冗余代码（不让其大篇的显示在前台上）

（1）封装CSS和JS代码，使用调用的方式在前台进行调用。是开发看起来简洁和易于管理，可达到重用。

　　  由于asp.netMVC4 框架 ，在封装js和CSS的时候，有如下规范：

using System.Web;
using System.Web.Optimization;

注释：这里是把要处理（封装的js和Css目录）bundles.Add（new function()）;

例如：

<!--定义下拉框的样式-->
<style type="text/css">
    .w_100
    {
        /*以此来控制该下拉框的长度，可按需要添加多个长度Class，如w_100，w_200*/
        width: 262px !important;
        height: 23px;
    }
</style>
<!--js开始-->
<script language="javascript" type="text/javascript">
    function chg() {
        if ($("#sel").val() == "New") {
            $("#inputGName").show();
            $("#GName").hide();             //  var o = document.form1.sel;
        }
        else {   //if ($("#sel").val() == "Ole")
            $("#GName").show();
            $("#inputGName").hide();

        }
    }
