为什么要使用@ Scripts.Render(“〜/bundles/jquery") [英] Why use @Scripts.Render("~/bundles/jquery")

问题描述

如何

@Scripts.Render("~/bundles/jquery")

不同于仅引用html这样的脚本

differ from just referencing the script from html like this

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

是否有性能提升?

推荐答案

捆绑是关于将多个JavaScript或样式表文件压缩而无需进行任何格式化(也称为最小化)到单个文件中，以节省带宽和加载请求的次数.页面.

Bundling is all about compressing several JavaScript or stylesheets files without any formatting (also referred as minified) into a single file for saving bandwith and number of requests to load a page.

例如，您可以创建自己的捆绑软件:

As example you could create your own bundle:

bundles.Add(New ScriptBundle("~/bundles/mybundle").Include(
            "~/Resources/Core/Javascripts/jquery-1.7.1.min.js",
            "~/Resources/Core/Javascripts/jquery-ui-1.8.16.min.js",
            "~/Resources/Core/Javascripts/jquery.validate.min.js",
            "~/Resources/Core/Javascripts/jquery.validate.unobtrusive.min.js",
            "~/Resources/Core/Javascripts/jquery.unobtrusive-ajax.min.js",
            "~/Resources/Core/Javascripts/jquery-ui-timepicker-addon.js"))

并像这样渲染它:

@Scripts.Render("~/bundles/mybundle")

@Scripts.Render("~/bundles/mybundle")相对于本机<script src="~/bundles/mybundle" />的另一个优点是@Scripts.Render()将遵守web.config调试设置:

One more advantage of @Scripts.Render("~/bundles/mybundle") over the native <script src="~/bundles/mybundle" /> is that @Scripts.Render() will respect the web.config debug setting:

  <system.web>
    <compilation debug="true|false" />

如果为debug="true"，则它将为每个源脚本呈现单独的脚本标签，而不会进行任何缩小.

If debug="true" then it will instead render individual script tags for each source script, without any minification.

对于样式表，您将必须使用StyleBundle和@ Styles.Render().

For stylesheets you will have to use a StyleBundle and @Styles.Render().

将所有文件压缩为单个JavaScript或样式表文件并一起加载，而不是通过单个请求(使用脚本或链接标签)加载每个脚本或样式.

Instead of loading each script or style with a single request (with script or link tags), all files are compressed into a single JavaScript or stylesheet file and loaded together.
