Question

我经常在没有询问的情况下找到答案，而不是这次。已经好几天了，所以我想我会问。

我在下面的html代码：

你会看到我试图做一些事情来查看错误
我测试过以确保js库正在加载（包括Google和jquery）
我尝试从bootstrap网站重新下载bootstrap.min.js（无变化）
我尝试通过CDN获取bootstrap.min.js
我确定答案很简单，但我无法弄明白（底部的jsfiddle链接）

非常感谢任何帮助。

这是jsfiddle工作的地方 - http://jsfiddle.net/moseslo/D2Gsa/1/

Answer 1

修正错误的撇号：

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

为什么要两次加载bootstrap.min.js？

Answer 2

尝试在此处仅使用一个Bootstrap JS版本，因此您可以删除：

<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>

Answer 3

有两种可能性，应该在控制台上显示错误：

你错了“<script src=”js/bootstrap.min.js”></script>
您没有托管您的页面，而是使用file://方案查看您的页面。

无论如何，下面的固定代码：
