unable to toggle collapse functionality of bootstrap 3 navbar

My navbar was recently modified, but now the toggle button is not responding when clicked. Here is the code I am using. Can someone help me find the mistake?

CODE:

  <body>
    <div class="navbar-wrapper">
      <div class="container">

        <div class="navbar navbar-default navbar-static-top" role="navigation">
          <div class="container">
            <div class="navbar-header">
              <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar collapse">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>  
                  <span class="icon-bar"></span>
              </button>
              <a class="navbar-brand" href="./index.html">ossoc</a>
            </div>
            <div class="collapse navbar-collapse">
              <ul class="nav navbar-nav navbar-right">
                <button id="loginbutton" type="button" class="btn btn-primary narbar-btn"><i class="glyphicon glyphicon-log-in"></i>Login</button>
                <button type="button" class="btn btn-success navbar-btn"><i class="glyphicon glyphicon-link"></i><a href="./register.jsp">Create account</a></button>
              </ul>
            </div>
          </div>
        </div>

Answer №1

While troubleshooting a similar issue, I carefully examined the HTML code multiple times, confident that it was accurate. However, after experimenting with the sequence of jQuery and Bootstrap JavaScript files, I discovered a solution.

Initially, I had bootstrap.min.js loading before jquery.min.js. As a result, the menu failed to expand when clicking on the menu icon.

After rearranging the order so that bootstrap.min.js came after jquery.min.js, the problem was resolved. Although I lack a deep understanding of JavaScript, this adjustment effectively addressed the issue.

Some additional details to note:

Both scripts are positioned at the bottom of the page, just before the closing <\body> tag. Both scripts are accessed from Content Delivery Networks (CDNs) rather than being hosted locally.

If you find yourself in a similar predicament despite believing your code to be correct, consider testing this solution.

To make the necessary changes in this code snippet

<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar collapse">

simply update the

data-target=".navbar collapse"

to

data-target=".navbar-collapse"

This adjustment is needed because the value of data-target should be a class name that corresponds to the associated navigation bar div. In this example, it should be

<div class="collapse navbar-collapse">  <-- Make sure to check here
     <ul class="nav navbar-nav navbar-right">
     .....
</div>

Ensure that within the <body> tag, you include two <script> elements:

<script src="https://code.jquery.com/jquery-2.1.3.js"></script>
<script src="js/bootstrap.js"></script>

The first <script> tag is responsible for fetching jQuery from the content delivery network (CDN), while the second <script> element loads Bootstrap's Javascript from a specified local directory named js.

Recently, I encountered an issue with a jquery.min.js file downloaded from the bootstrap site. It wasn't functioning properly on my webpage. After trying a different jquery.min.js file, the problem was resolved. If you experience a similar issue, consider referencing an alternate jquery.min.js file on your page and see if that solves the problem.

My thoughts on this matter:

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

Initially placed at the bottom of the body tag, it did not function properly. However, upon adding crossorigin="anonymous", Bootstrap version 3.3.6 started working flawlessly...

My Nav bar issue stemmed from how I constructed it using a jQuery plugin for quick Bootstrap component creation through JavaScript.

Long story short, using jQuery .data() to bind button data elements led to a dysfunctional collapse button. Switching to .attr() resolved the problem.

The ineffective code:

$this.addClass("navbar navbar-default")
  .append($("<div />").addClass("container-fluid")
    .append($("<div />").addClass("navbar-header")
      .append($("<button />").addClass("navbar-toggle collapsed")
        .attr("type","button")
        .attr("aria-expanded", "false")
        .data("target","#" + id)
        .data("toggle","collapse")
        .html("<span class='sr-only'>Toggle navigation</span>"
            + "<span class='icon-bar'></span>"
            + "<span class='icon-bar'></span>"
            + "<span class='icon-bar'></span>"))
        .append($("<a href='#' />").addClass("navbar-brand")
          .append(document.createTextNode(settings.label))))
    .append($("<div />").addClass("collapse navbar-collapse").attr("id",id)));

However, this revised version (changes noted in comments) works:

$this.addClass("navbar navbar-default")
  .append($("<div />").addClass("container-fluid")
    .append($("<div />").addClass("navbar-header")
      .append($("<button />").addClass("navbar-toggle collapsed")
        .attr("type","button")
        .attr("aria-expanded", "false")
        .attr("data-target", "#" + id) //.data("target","#" + id)
        .attr("data-toggle", "collapse") // .data("toggle","collapse")
        .html("<span class='sr-only'>Toggle navigation</span>"
            + "<span class='icon-bar'></span>"
            + "<span class='icon-bar'></span>"
            + "<span class='icon-bar'></span>"))
        .append($("<a href='#' />").addClass("navbar-brand")
          .append(document.createTextNode(settings.label))))
    .append($("<div />").addClass("collapse navbar-collapse").attr("id",id)));

It seems that jQuery's .data() method doesn't write attributes directly to elements, only attaching them to the jQuery object. The HTML output with .data() was:

<button class="navbar-toggle collapsed" aria-expanded="false" type="button" >

Whereas using .attr() produced:

<button class="navbar-toggle collapsed" aria-expanded="false" type="button" data-toggle="collapse" data-target="#6a2034fe-8922-4edd-920e-6bd0ea0b2caf">

Sharing my experience in case it can benefit others. I encountered a similar issue after integrating Bootstrap 3 into my MVC 4 project. The problem was traced back to referencing bootstrap-min.js instead of bootstrap.js in my BundleConfig.cs.

Initial attempt:

bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                            "~/Scripts/bootstrap-min.js"));

Successful correction:

bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                        "~/Scripts/bootstrap.js"));
