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)
代码如下:
<?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>
<File>~/Content/themes/base/jquery.ui.selectable.css</File>
<File>~/Content/themes/base/jquery.ui.accordion.css</File>
<File>~/Content/themes/base/jquery.ui.autocomplete.css</File>
<File>~/Content/themes/base/jquery.ui.button.css</File>
<File>~/Content/themes/base/jquery.ui.dialog.css</File>
<File>~/Content/themes/base/jquery.ui.slider.css</File>
<File>~/Content/themes/base/jquery.ui.tabs.css</File>
<File>~/Content/themes/base/jquery.ui.datepicker.css</File>
<File>~/Content/themes/base/jquery.ui.progressbar.css</File>
<File>~/Content/themes/base/jquery.ui.theme.css</File>
</Style>
<Style Path="~/Content/css">
<File>~/Content/site.css</File>
</Style>
</Styles>
</root>
代码文件：BundleConfig.cs
代码如下:
public class BundleConfig
{
public static string BundleConfigPath = "~/Config/BundleConfig.xml";
/// <summary>
/// Register Bundles From XML
/// </summary>
/// <param name="bundles"></param>
public static void RegisterBundles(BundleCollection bundles)
{
XmlDocument doc = new XmlDocument();
doc.Load(HttpContext.Current.Server.MapPath(BundleConfigPath));
XmlNode root = doc.DocumentElement;
// Regester Script
XmlNodeList ScriptList = root.SelectNodes("Scripts/Script");
if (ScriptList != null && ScriptList.Count > 0)
{
foreach (XmlNode node in ScriptList)
{
string path = CheckNodeRegedit(node);
if (string.IsNullOrEmpty(path)) continue;
var bound = new ScriptBundle(path);
List<string> files = GetFilesFormNode(node);
if (files.Count > 0)
{
bound.Include(files.ToArray());
bundles.Add(bound);
}
}
}
// Regester Style
XmlNodeList StyleList = root.SelectNodes("Styles/Style");
if (StyleList != null && StyleList.Count > 0)
{
foreach (XmlNode node in StyleList)
{
string path = CheckNodeRegedit(node);
if (string.IsNullOrEmpty(path)) continue;
var bound = new StyleBundle(path);
List<string> files = GetFilesFormNode(node);
if (files.Count > 0)
{
bound.Include(files.ToArray());
bundles.Add(bound);
}
}
}
doc = null;
}
/// <summary>
/// 如果内容为空则不添加
/// </summary>
/// <param name="node"></param>
/// <returns></returns>
private static List<string> GetFilesFormNode(XmlNode node)
{
List<string> files = new List<string>();
foreach (XmlNode nodeFile in node.ChildNodes)
{
if (!string.IsNullOrEmpty(nodeFile.InnerText.Trim()))
files.Add(nodeFile.InnerText.Trim());
}
return files;
}
/// <summary>
/// 检查注册的Node
/// </summary>
/// <param name="node"></param>
/// <returns></returns>
private static string CheckNodeRegedit(XmlNode node)
{
XmlAttribute pathAtt = node.Attributes["Path"];
string path = string.Empty;
if (pathAtt == null || string.IsNullOrEmpty(pathAtt.Value.Trim()) || node.ChildNodes.Count == 0)
return string.Empty;
else
return pathAtt.Value.Trim();
}
}
