Bootstrap 折叠导航栏适用于 jsfiddle，不适用于实际网站答案

【问题标题】：Bootstrap collapse navbar works on jsfiddle, doesn't work on actual websiteBootstrap 折叠导航栏适用于 jsfiddle，不适用于实际网站
【发布时间】：2014-03-26 07:08:39
【问题描述】：

我通常不用问就能找到简单问题的答案，但这次不行。已经好几天了，所以我想我会问。

我的html代码如下：

你会看到我尝试做一些事情来找出问题所在
我进行了测试以确保 js 库正在加载（Google 和 jquery）
我尝试从 bootstrap 网站重新下载 bootstrap.min.js（没有变化）
我尝试通过 CDN 获取 bootstrap.min.js
我确定答案很简单，但我无法完全弄清楚（底部的 jsfiddle 链接）

任何帮助将不胜感激。

【问题讨论】：

标签： javascript jquery twitter-bootstrap navbar

【解决方案1】：

修正错误的撇号：

<script src=”js/bootstrap.min.js”></script>

你为什么要加载 bootstap.min.js 两次？

【讨论】：

【解决方案2】：

这里尽量只使用一个Bootstrap JS版本，这样可以去掉：

<script src=”js/bootstrap.min.js”></script>

并且只保留：

<script type="text/javascript" src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>

【解决方案3】：

有两种可能，应该在控制台显示错误：

<script src=”js/bootstrap.min.js”></script>你错了”
您不托管您的页面，您使用file:// 方案来查看您的页面。
