扩展asp.net Bundle

前言

新建Asp.net  MVC4项目的时候,在Global.asax.cs里面发现多了一句代码

BundleConfig.RegisterBundles(BundleTable.Bundles)

google了以后终于弄清楚了这个的作用，发现这个东西确实非常实用，且功能强大，能够压缩合并js和CSS，但是目前的使用起来不是特别好，如果添加js或者css文件的话，需要修改BundleConfig的代码。

这里我自己简单修改了BundleConfig，对这个进行简单的扩展。

下面贴出代码：

先贴配置文件BundleConfig.xml(文件放在网站目录下路径见代码中变量BundleConfigPath)

<?xml version="1.0" encoding="utf-8" ?>
<root>
<Scripts>
<Script Path="~/bundles/jquery">
<File>~/Scripts/jquery-{version}.js</File>
</Script>
<Script Path="~/bundles/jqueryui">
<File>~/Scripts/jquery-ui-{version}.js</File>
</Script>
<Script Path="~/bundles/jqueryval">
<File>~/Scripts/jquery.unobtrusive*</File>
<File>~/Scripts/jquery.validate*</File>
</Script>
<Script Path="~/bundles/modernizr">
<File>~/Scripts/modernizr-*</File>
</Script>
<Script Path="~/bb/aa">
<File>~/Views/Home/addda.js</File>
</Script>
</Scripts>
<Styles>
<Style Path="~/Content/themes/base/css">
<File>~/Content/themes/base/jquery.ui.core.css</File>
<File>~/Content/themes/base/jquery.ui.resizable.css</File>

</Style>
<Style Path="~/Content/css">

</Style>
</Styles>
</root>
