Need to load bootstrap-dropdown.js after bootstrap.js to make dropdown work - why?
提问by Bryan Hanson
New to bootstrap and javascriptand was trying to build a fairly minimal example of a dropdown menu. I am using bootstrap 2.3.2which is the current version. My cssand jsare visible in my IDE. From the bootstrapdocs it seems that a standard install of bootstrap.jscontains bootstrap-dropdown.jsand I can see it in the file. Yet, I need to have the following for the drop down menu to work:
bootstrap 的新手，javascript并试图构建一个相当小的下拉菜单示例。我正在使用bootstrap 2.3.2哪个是当前版本。我的css和js在我的 IDE 中可见。从bootstrap文档看来，标准安装bootstrap.js包含bootstrap-dropdown.js，我可以在文件中看到它。但是，我需要以下内容才能使下拉菜单正常工作：
<script src="http://code.jquery.com/jquery.js"></script>
<script src="assets/js/bootstrap.min.js"></script>
<script src="assets/js/bootstrap.js"></script>
<script src="http://twitter.github.com/bootstrap/assets/js/bootstrap-dropdown.js"></script>
Why do I have to load bootstrap-dropdown.jsseparately if it is included in bootstrap.js? Obviously there is something fundamental here that I don't understand. Thanks.
bootstrap-dropdown.js如果包含在 中，为什么我必须单独加载bootstrap.js？显然，这里有一些我不明白的基本原理。谢谢。

From Bootstrap website :
从 Bootstrap 网站：
Plugins can be included individually (though some have required dependencies), or all at once. Both bootstrap.js and bootstrap.min.js contain all plugins in a single file.
插件可以单独包含（尽管有些插件需要依赖项），也可以同时包含所有插件。bootstrap.js 和 bootstrap.min.js 都在一个文件中包含所有插件。
Both bootstrap.jsand bootstrap.min.jscontain all plugins in a single file. you do not need the bootstrap-dropdown.jsif you include bootstrap.min.jsor bootstrap.jsfrom the bootstrap page, check this overview on Bootstrap site. i can see that you are including both bootstrap.min.jsand bootstrap.jsbut only one is enough.
Check the demo here, only using bootstrap.js.
双方bootstrap.js并bootstrap.min.js包含在一个单一文件中的所有插件。bootstrap-dropdown.js如果您包含bootstrap.min.js或bootstrap.js从引导程序页面，您不需要，请在引导程序站点上查看此概述。我可以看到您同时包含了两者bootstrap.min.js，bootstrap.js但只有一个就足够了。
在此处查看演示，仅使用bootstrap.js.
Also, you can download a customized version from here, just according to your need you can add components/plugins and then download the custom build.
另外，您可以从这里下载定制版本，根据您的需要，您可以添加组件/插件，然后下载定制版本。
