Twitter Bootstrap 下拉菜单在任何浏览器中都不起作用

本文介绍了Twitter Bootstrap 下拉菜单在任何浏览器中都不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试做一个下拉菜单，它似乎在 Jsfiddle 中工作.似乎 javascript 和 css 文件已正确加载:http://imgur.com/YYiJS4p

但它在我的任何浏览器中都不起作用.我已经在 Firefox 19.0.2、Google Chrome 25.0.1364.172 和 Internet Explorer 9.0.2 中对其进行了测试.Javascript 已启用并正在运行.

Javascript 包含在 Bootstrap 之前，bootstrap-dropdown.js 是我包含的唯一引导文件，我的意思是我没有包含 bootstrap.js.

我的错误控制台中没有任何内容.

提前致谢.

解决方案

这是我正在加载的内容:

 <script src="bootstrap/js/bootstrap.js"></script>

我尝试了你的代码，加载了我机器上的引导程序和来自站点的 jquery.它在 FF、chrome 和 safari 中完美运行.我没有资源管理器来测试它.

I'm trying to do a dropdown menu and it seems to work in Jsfiddle. It seems that the javascript and css files are correctly loaded:http://imgur.com/YYiJS4p

But it doesn't work in any of my browsers. I have tested it in Firefox 19.0.2, Google Chrome 25.0.1364.172 and Internet Explorer 9.0.2. Javascript is enabled and running.

Javascript is included before Bootstrap and bootstrap-dropdown.js is the only bootstrap file I have included, I mean that I have not included bootstrap.js.

There is nothing in my error console.

Thanks in advance.

解决方案

This is what i'm loading: 

 <script src="http://code.jquery.com/jquery.js"></script>
 <script src="bootstrap/js/bootstrap.js"></script>

I tried your code, loading a bootrasp I have in my machine and a the jquery from the site. and it works perfectly in FF, chrome and safari. I don't have a explorer to test it.
