Bootstrap - dropdown menu not working?

Question

My dropdown menu in Bootstrap doesnt appear to be working - can anyone alert me to the problem? Right now it displays the dropdown, but clicking it does nothing. Thanks!

Answer 1

This is a Rails specific answer, but I had this same problem with Bootstrap dropdown menus in my Rails app. What fixed it was adding this to app/assets/javascripts/application.js:

//= require bootstrap

Hope that helps someone.

If I am getting you correctly, when you say that clicking does nothing, do you mean that it does not point to your URL?

In the anchor tag <a href>it looks like you did not pass your file path to the href attribute. So, replace the # with your actual path for the file that you want to link.

<li><a href="#">Action</a></li>
<li><a href="action link here">Another action</a></li>
<li><a href="something else link here">Something else here</a></li>
<li class="divider"></li>
<li><a href="seperated link here">Separated link</a></li>

I hope this helps with your issue.

you are missing the "btn btn-navbar" section. For example:

        <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </a>

Take a look to navbar documentation in:

Twitter Bootstrap

I had a similar problem. The version of bootstrap.js that visual studio seems to be hosed. I just pointed to this URL instead:

    <link id="active_style" rel="stylesheet" href="//netdna.bootstrapcdn.com/bootswatch/3.1.1/cosmo/bootstrap.min.css">

For completeness, here's the HTML and javascript

<ul class="nav navbar-nav navbar-right">
                    <li id="theme_selector" class="dropdown">
                        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Theme <b class="caret"></b></a>
                        <ul id="theme" class="dropdown-menu" role="menu">
                            <li><a href="#">Amelia</a></li>
                            <li><a href="#">Cerulean</a></li>
                            <li><a href="#">Cyborg</a></li>
                            <li><a href="#">Cosmo</a></li>
                            <li><a href="#">Darkly</a></li>
                            <li><a href="#">Flatly</a></li>
                            <li><a href="#">Lumen</a></li>
                            <li><a href="#">Simplex</a></li>
                            <li><a href="#">Slate</a></li>
                            <li><a href="#">Spacelab</a></li>
                            <li><a href="#">Superhero</a></li>
                            <li><a href="#">United</a></li>
                            <li><a href="#">Yeti</a></li>
                        </ul>
                    </li>
                </ul>

Javascript

$('#theme li').click(function () {
        //alert('item: ' + $(this).text());
        switch_style($(this).text());
    });

If you are using electron or other chromium frame, you have to include jquery within window explicitly by:

<script language="javascript" type="text/javascript" src="local_path/jquery.js" onload="window.$ = window.jQuery = module.exports;"></script>

Answer 6

Double importing jquery can cause Error

<script src="static/public/js/jquery/jquery.min.js"></script>

OR

<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="" crossorigin="anonymous"></script>
