Bootstrap 3: Keep selected tab on page refresh

Question

I am trying to keep selected tab active on refresh with Bootstrap 3. Tried and checked with some question already been asked here but none of work for me. Don't know where I am wrong. Here is my code

HTML

<!-- tabs link -->
<ul class="nav nav-tabs" id="rowTab">
    <li class="active"><a href="#personal-info" data-toggle="tab">Personal Information</a></li>
    <li><a href="#Employment-info" data-toggle="tab">Employment Information</a></li>
    <li><a href="#career-path" data-toggle="tab">Career Path</a></li>
    <li><a href="#warnings" data-toggle="tab">Warning</a></li>
</ul>
<!-- end: tabs link -->

<div class="tab-content">
    <div class="tab-pane active" id="personal-info">
        tab data here...
    </div>

    <div class="tab-pane" id="Employment-info">
        tab data here...
    </div>

    <div class="tab-pane" id="career-path">
        tab data here...
    </div>

    <div class="tab-pane" id="warnings">
        tab data here...
    </div>
</div>

Javascript:

// tab
$('#rowTab a:first').tab('show');

//for bootstrap 3 use 'shown.bs.tab' instead of 'shown' in the next line
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
//save the latest tab; use cookies if you like 'em better:
localStorage.setItem('selectedTab', $(e.target).attr('id'));
});

//go to the latest tab, if it exists:
var selectedTab = localStorage.getItem('selectedTab');
if (selectedTab) {
  $('#'+selectedTab).tab('show');
}

Answer 1

This is the best one that I tried:

$(document).ready(function() {
    if (location.hash) {
        $("a[href='" + location.hash + "']").tab("show");
    }
    $(document.body).on("click", "a[data-toggle]", function(event) {
        location.hash = this.getAttribute("href");
    });
});
$(window).on("popstate", function() {
    var anchor = location.hash || $("a[data-toggle='tab']").first().attr("href");
    $("a[href='" + anchor + "']").tab("show");
});

A mix between others answers:

• No jump on click
• Save on location hash
• Save on localStorage (e.g: for form submit)

• Just copy&paste ;)

  if (location.hash) {
    $('a[href=\'' + location.hash + '\']').tab('show');
  }
  var activeTab = localStorage.getItem('activeTab');
  if (activeTab) {
    $('a[href="' + activeTab + '"]').tab('show');
  }
  
  $('body').on('click', 'a[data-toggle=\'tab\']', function (e) {
    e.preventDefault()
    var tab_name = this.getAttribute('href')
    if (history.pushState) {
      history.pushState(null, null, tab_name)
    }
    else {
      location.hash = tab_name
    }
    localStorage.setItem('activeTab', tab_name)
  
    $(this).tab('show');
    return false;
  });
  $(window).on('popstate', function () {
    var anchor = location.hash ||
      $('a[data-toggle=\'tab\']').first().attr('href');
    $('a[href=\'' + anchor + '\']').tab('show');
  });
  

Answer 3

Thanks for sharing.

By reading all the solutions. I came up with a solution that uses the url hash or localStorage depending on the availability of the latter with below code:

$(function(){
    $(document).on('shown.bs.tab', 'a[data-toggle="tab"]', function (e) {
        localStorage.setItem('activeTab', $(e.target).attr('href'));
    })

    var hash = window.location.hash;
    var activeTab = localStorage.getItem('activeTab');

    if(hash){
          $('#project-tabs  a[href="' + hash + '"]').tab('show');   
    }else if (activeTab){
        $('#project-tabs a[href="' + activeTab + '"]').tab('show');
    }
});

Answer 4

This one use HTML5 localStorage to store active tab

$('a[data-toggle="tab"]').on('shown.bs.tab', function(e) {
    localStorage.setItem('activeTab', $(e.target).attr('href'));
});
var activeTab = localStorage.getItem('activeTab');
if (activeTab) {
   $('#navtab-container a[href="' + activeTab + '"]').tab('show');
}

Answer 5

Basing myself on answers provided by Xavi Martínez and koppor I came up with a solution that uses the url hash or localStorage depending on the availability of the latter:

function rememberTabSelection(tabPaneSelector, useHash) {
    var key = 'selectedTabFor' + tabPaneSelector;
    if(get(key)) 
        $(tabPaneSelector).find('a[href=' + get(key) + ']').tab('show');

    $(tabPaneSelector).on("click", 'a[data-toggle]', function(event) {
        set(key, this.getAttribute('href'));
    }); 

    function get(key) {
        return useHash ? location.hash: localStorage.getItem(key);
    }

    function set(key, value){
        if(useHash)
            location.hash = value;
        else
            localStorage.setItem(key, value);
    }
}

Usage:

$(document).ready(function () {
    rememberTabSelection('#rowTab', !localStorage);
    // Do Work...
});

It does not keep up with the back button as is the case for Xavi Martínez's solution.

Answer 6

In addition to Xavi Martínez's answer avoiding the jump on click

Avoiding Jump

$(document).ready(function(){

    // show active tab

    if(location.hash) {

        $('a[href=' + location.hash + ']').tab('show');
    }

    // set hash on click without jumb

    $(document.body).on("click", "a[data-toggle]", function(e) {

        e.preventDefault();

        if(history.pushState) {

            history.pushState(null, null, this.getAttribute("href"));
        }
        else {

            location.hash = this.getAttribute("href");
        }

        $('a[href=' + location.hash + ']').tab('show');

        return false;
    });
});

// set hash on popstate

$(window).on('popstate', function() {

    var anchor = location.hash || $("a[data-toggle=tab]").first().attr("href");

    $('a[href=' + anchor + ']').tab('show');
});

Nested tabs

implementation with "_" character as separator

$(document).ready(function(){

    // show active tab

    if(location.hash) {

        var tabs = location.hash.substring(1).split('_');

        $.each(tabs,function(n){

            $('a[href=#' + tabs[n] + ']').tab('show');
        });         

        $('a[href=' + location.hash + ']').tab('show');
    }

    // set hash on click without jumb

    $(document.body).on("click", "a[data-toggle]", function(e) {

        e.preventDefault();

        if(history.pushState) {

            history.pushState(null, null, this.getAttribute("href"));
        }
        else {

            location.hash = this.getAttribute("href");
        }

        var tabs = location.hash.substring(1).split('_');

        //console.log(tabs);

        $.each(tabs,function(n){

            $('a[href=#' + tabs[n] + ']').tab('show');
        });

        $('a[href=' + location.hash + ']').tab('show');

        return false;
    });
});

// set hash on popstate

$(window).on('popstate', function() {

    var anchor = location.hash || $("a[data-toggle=tab]").first().attr("href");

    var tabs = anchor.substring(1).split('_');

    $.each(tabs,function(n){

        $('a[href=#' + tabs[n] + ']').tab('show');
    });

    $('a[href=' + anchor + ']').tab('show');
});
