<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">

 </button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">

There it is. 在那里。 but for some reason, the bootstrap js script isn't running so when I click the button nothing is happening... 但是由于某种原因，bootstrap js脚本没有运行，所以当我单击按钮时，什么也没有发生...

anybody able to give me a hand? 有人可以帮我吗？

Thanks, Jonathan 谢谢乔纳森

It's because you're using a protocol-relative URL for jQuery. 这是因为您正在使用jQuery的协议相对URL。 You should be seeing errors in the browser's console. 您应该在浏览器的控制台中看到错误。

Try changing: 尝试更改：

<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>

to: 至：

<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>

When you open a file locally in your browser (outside of a web server) most browser's will use the file:// protocol, so //code.jquery.com/jquery-1.11.3.min.js becomes file://code.jquery.com/jquery-1.11.3.min.js and odds are that you don't have jQuery that location. 当您在浏览器中（在Web服务器外部）在本地打开文件时，大多数浏览器将使用file://协议，因此//code.jquery.com/jquery-1.11.3.min.js变为file://code.jquery.com/jquery-1.11.3.min.js ，奇怪的是您没有jQuery所在的位置。
