Store the active tab in AngularJS with Bootstrap to easily remember and display

After creating a basic AngularJS application with the Bootstrap directive, I noticed that some of my pages have tabs. The issue arises when I am on a tab other than the first one and click a link to navigate to another view. Upon returning (using either the back button in the browser or within the application), the previously active tab is no longer highlighted.

My suspicion is that Angular utilizes pushState or a similar method to track previous pages, as the length property of window.history increases during navigation within the app. Is there a way for me to include additional data in this state information to remember which tab was active?

I attempted using pushState to add a tab parameter to the URL. Although it worked smoothly the first time, subsequent attempts resulted in an Angular loop causing the page to eventually crash. How can I resolve this without triggering such issues?

Answer №1

By combining various solutions and refining them, I was able to find a working solution that allowed me to use AngularJS with Bootstrap Tabs. The key is to utilize HTML5 pushstate to extract the URL hash from the browser history in JavaScript, locate the corresponding tab, and display it.

The tabs are structured as follows:

<ul class="nav nav-tabs" role="tablist" id="myTab">
    <li class="active"><a href="#" data-target="#">Home</a></li>
    <li><a href="#/tab2" data-target="#">Tab 2</a></li>
    <li><a href="#/tab3" data-target="#">Tab 3</a></li>
</ul>

This piece of JavaScript code will activate the appropriate tab based on the history or if the user arrives at the page through a bookmark:

function setActiveTab() {
    var hash = window.location.hash;

    var activeTab = $('.nav-tabs a[href="' + hash + '"]');
    if (activeTab.length) {
        activeTab.tab('show');
    } else {
        $('.nav-tabs a:first').tab('show');
    }
};

//Ensure that when navigating to a page via a bookmark, 
//the correct tab is activated after the initial load:
$(document).ready(function() {
    setActiveTab();
});

//When history.pushState() triggers the popstate event, switch to the currently
//selected tab that corresponds to the page being navigated to in the history.
$(window).on('popstate', function () {
    setActiveTab();
});
