Twitter Bootstrap Tabs: Go to Specific Tab on Page Reload or Hyperlink

I'm developing a web page in which I'm using Twitter's Bootstrap Framework and their Bootstrap Tabs JS. It works great except for a few minor issues, one of which is I do not know how go directly to a specific tab from an external link. For example:

<a href="facility.php#home">Home</a>
<a href="facility.php#notes">Notes</a>

should go to the Home tab and the Notes tab respectively when clicked on the links from an external page

wish this was built in!
This question has also been brought up here: github.com/twitter/bootstrap/issues/2415 (and has a couple of solutions there).
Updated link to bootstrap issue is github.com/twbs/bootstrap/issues/2415
Plugin that fixes this: github.com/timabell/jquery.stickytabs

Here is my solution to the problem, a bit late perhaps. But it could maybe help others:

// Javascript to enable link to tab
var hash = location.hash.replace(/^#/, '');  // ^ means starting, meaning only match the first hash
if (hash) {
    $('.nav-tabs a[href="#' + hash + '"]').tab('show');
} 

// Change hash for page-reload
$('.nav-tabs a').on('shown.bs.tab', function (e) {
    window.location.hash = e.target.hash;
})

I'd add 1 more extra line window.scrollTo(0, 0); to make sure the Window always scroll to the top
$('.nav-tabs a[href*=#'+url.split('#')[1]+']').tab('show') ; // With an * is safer since it otherwise it only matches the first #...
Online that worked for me: window.location.hash && $('li a[href="' + window.location.hash+ '"]').tab('show').trigger("click");
Here's a demo for Bootstrap 3: bootply.com/render/VQqzOawoYc#tab2 and the source code
After upgrade jquery to 1.11 from 1.09 I get this error: Syntax error, unrecognized expression: .nav-tabs a[href=#tab-2]. Solved using stackoverflow.com/questions/12131273/…

UPDATE

For Bootstrap 3, change .on('shown', ...) to .on('shown.bs.tab', ....)

This is based off of @dubbe answer and this SO accepted answer. It handles the issue with window.scrollTo(0,0) not working correctly. The problem is that when you replace the url hash on tab shown, the browser will scroll to that hash since its an element on the page. To get around this, add a prefix so the hash doesn't reference an actual page element

// Javascript to enable link to tab
var hash = document.location.hash;
var prefix = "tab_";
if (hash) {
    $('.nav-tabs a[href="'+hash.replace(prefix,"")+'"]').tab('show');
} 

// Change hash for page-reload
$('.nav-tabs a').on('shown', function (e) {
    window.location.hash = e.target.hash.replace("#", "#" + prefix);
});

Example of use

If you have tab-pane with id="mytab" you need to put your link like this:

<a href="yoursite.com/#tab_mytab">Go to Specific Tab </a>

Would there be a simple way to reference bookmarks which are located under a specific tab? I have five tabs on my page, and under those I have a number of bookmarks. What I would like is to make these bookmarks linkable from outside the tab.
@nize if you create a jsfiddle with what you are trying to do I will try to take a look.
Here's a Bootlpy demo for Bootstrap 3: bootply.com/render/VQqzOawoYc#tab2 and the source code
The example above is missing the double quotes on the href. line 5 should be: $('.nav-tabs a[href="'+hash.replace(prefix,"")+'"]').tab('show');
Works for me except that I had to remove the last forward slash (before the #) in 'yoursite.com/anotherpage/#tab_mytab' otherwise it played havoc with the page loading.

you could trigger a click event on the corresponding tab link:

$(document).ready(function(){

  if(window.location.hash != "") {
      $('a[href="' + window.location.hash + '"]').click()
  }

});

Thanks for the tip! This worked great with one small problem. Refreshing the page, would not take it to the correct tab. Hitting Ctrl+F5 would. I modified the code to the following: ` $(document).ready(function(){ function getUrlVars() { var vars = {}; var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) { vars[key] = value; }); return vars; } var action = getUrlVars()["action"]; if (action != "") { $('a[href="#' + action + '"]').click() }; }); `

This is an improved implementation of dubbe's solution which prevent scrolling.

// Javascript to enable link to tab
var url = document.location.toString();
if (url.match('#')) {
    $('.nav-tabs a[href="#'+url.split('#')[1]+'"]').tab('show') ;
} 

// With HTML5 history API, we can easily prevent scrolling!
$('.nav-tabs a').on('shown.bs.tab', function (e) {
    if(history.pushState) {
        history.pushState(null, null, e.target.hash); 
    } else {
        window.location.hash = e.target.hash; //Polyfill for old browsers
    }
})

While the JavaScript solution provided may work, I went a slightly different way that requires no additional JavaScript, but does require logic in your view. You create a link with a standard URL parameter, like:

<a href = "http://link.to.yourpage?activeTab=home">My Link</a>

Then you simply detect the value of activeTab to write 'class="active"' in the appropriate <li>

Pseudocode (implement accordingly in your language). Note I've set 'home' tab as a default active if no parameter provided in this example.

$activetabhome = (params.activeTab is null or params.activeTab == 'home') ? 'class="active"' : '';
$activetabprofile = (params.activeTab == 'profile') ? 'class="active"' : '';

<li $activetabhome><a href="#home">Home</a></li>
<li $activetabprofile><a href="#profile">Profile</a></li>

I prefer your solution to the JS solution due to one simple reason is that JS location.hash would jump to the ID which cause the position of the cursor goes up and down.
I prefer this solution. In fact, i created new routes for tabs and re-generated view by setting active class accordingly. This avoids headache of page resize, url hash and page scrolling all together.
A better solution.

I am not a big fan of if...else; so I took a simpler approach.

$(document).ready(function(event) {
    $('ul.nav.nav-tabs a:first').tab('show'); // Select first tab
    $('ul.nav.nav-tabs a[href="'+ window.location.hash+ '"]').tab('show'); // Select tab by name if provided in location hash
    $('ul.nav.nav-tabs a[data-toggle="tab"]').on('shown', function (event) {    // Update the location hash to current tab
        window.location.hash= event.target.hash;
    })
});

Pick a default tab (usually the first) Switch to tab (if such an element is indeed present; let jQuery handle it); Nothing happens if a wrong hash is specified [Optional] Update the hash if another tab is manually chosen

Doesn't address scrolling to requested hash; but should it?

For Bootstrap 3:

$('.nav-tabs a[href="#' + tabID + '"]').tab('show');

This works in Bootstrap 3 and improves dubbe and flynfish 's 2 top answers by integrating GarciaWebDev 's answer as well (which allows for url parameters after the hash and is straight from Bootstrap authors on the github issue tracker):

// Javascript to enable link to tab
var hash = document.location.hash;
var prefix = "tab_";

if (hash) {
    hash = hash.replace(prefix,'');
    var hashPieces = hash.split('?');
    activeTab = $('.nav-tabs a[href=' + hashPieces[0] + ']');
    activeTab && activeTab.tab('show');
} 

// Change hash for page-reload
$('.nav-tabs a').on('shown', function (e) {
    window.location.hash = e.target.hash.replace("#", "#" + prefix);
});

this doesn't work in Bootstrap 3, 'shown' should be 'shown.bs.tab' per the docs: getbootstrap.com/javascript/#tabs-events. I'm baffled as to why but when I tried to edit your post it got rejected...

Building on Demircan Celebi's solution; I wanted the tab to open when modifying the url and open tab without having to reload the page from the server.

<script type="text/javascript">
    $(function() {
        openTabHash(); // for the initial page load
        window.addEventListener("hashchange", openTabHash, false); // for later changes to url
    });


    function openTabHash()
    {
        console.log('openTabHash');
        // Javascript to enable link to tab
        var url = document.location.toString();
        if (url.match('#')) {
            $('.nav-tabs a[href="#'+url.split('#')[1]+'"]').tab('show') ;
        } 

        // With HTML5 history API, we can easily prevent scrolling!
        $('.nav-tabs a').on('shown.bs.tab', function (e) {
            if(history.pushState) {
                history.pushState(null, null, e.target.hash); 
            } else {
                window.location.hash = e.target.hash; //Polyfill for old browsers
            }
        })
    }
</script>

This code selects the right tab depending on the #hash and adds the right #hash when a tab is clicked. (this uses jquery)

In Coffeescript :

$(document).ready ->
    if location.hash != ''
        $('a[href="'+location.hash+'"]').tab('show')

    $('a[data-toggle="tab"]').on 'shown', (e) ->
        location.hash = $(e.target).attr('href').substr(1)

or in JS :

$(document).ready(function() {
    if (location.hash !== '') $('a[href="' + location.hash + '"]').tab('show');
    return $('a[data-toggle="tab"]').on('shown', function(e) {
      return location.hash = $(e.target).attr('href').substr(1);
    });
});

make sure to put this after jquery has loaded. I was putting it in the middle of a page (it was an easy place to insert it for testing) and it did not work. Putting it after I load jquery works great.

$(function(){
  var hash = window.location.hash;
  hash && $('ul.nav a[href="' + hash + '"]').tab('show');
});

This code from http://github.com/twitter/bootstrap/issues/2415#issuecomment-4450768 worked for me perfectly.

@flynfish + @Ztyx solution that I use for nested tabs:

    handleTabLinks();

    function handleTabLinks() {
        if(window.location.hash == '') {
            window.location.hash = window.location.hash + '#_';
        }
        var hash = window.location.hash.split('#')[1];
        var prefix = '_';
        var hpieces = hash.split('/');
        for (var i=0;i<hpieces.length;i++) {
            var domelid = hpieces[i].replace(prefix,'');
            var domitem = $('a[href=#' + domelid + '][data-toggle=tab]');
            if (domitem.length > 0) {
                domitem.tab('show');
            }
        }
        $('a[data-toggle=tab]').on('shown', function (e) {
            if ($(this).hasClass('nested')) {
                var nested = window.location.hash.split('/');
                window.location.hash = nested[0] + '/' + e.target.hash.split('#')[1];
            } else {
                window.location.hash = e.target.hash.replace('#', '#' + prefix);
            }
        });
    }

childrens should have class="nested"


Can you explain while you have / in hashes?

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');
    }
});

I would suggest you use the code provided by Bootstrap authors on their issue tracker on GitHub:

var hash = location.hash
  , hashPieces = hash.split('?')
  , activeTab = $('[href=' + hashPieces[0] + ']');
activeTab && activeTab.tab('show');

You can find on the link to the issue more information about why they didn't choose to support that.

Tried couple of ways discussed above and end up with following working solution, just copy and paste in your editor to try. To test just change hash to inbox, outbox, compose in url and hit enter key.

                <div id="outbox" class="tab-pane fade">

            </div>
        </div>
        <script>
            $(function () {
                var hash = window.location.hash;
                hash && $('ul.nav a[href="' + hash + '"]').tab('show');
            });
        </script>
    </body>
</html>

Hope this will save your time.

Just insert this code on your page:

$(function(){ var hash = window.location.hash; hash && $('ul.nav a[href="' + hash + '"]').tab('show'); $('.nav-tabs a').click(function (e) { $(this).tab('show'); var scrollmem = $('body').scrollTop(); window.location.hash = this.hash; $('html,body').scrollTop(scrollmem); }); });

Derek Buntin

Here is what i did, really simple, and provided your tab links have an ID associated with them you can get the href attribute and pass that over to the function that shows the tab contents:

<script type="text/javascript">
        jQuery(document).ready(function() {
            var hash = document.location.hash;
            var prefix = "tab_";
            if (hash) {
                var tab = jQuery(hash.replace(prefix,"")).attr('href');
                jQuery('.nav-tabs a[href='+tab+']').tab('show');
            }
        });
        </script>

Then in your url you can add the hash as something like: #tab_tab1, the 'tab_' part is removed from the hash itself so the ID of the actual tab link in the nav-tabs (tabid1) is placed after this, so your url would look something like: www.mydomain.com/index.php#tab_tabid1.

This works perfect for me and hope it helps someone else :-)

If it matters to anybody, the following code is small and works flawless, to get a single hash value from the URL and show that:

<script>
    window.onload = function () {
        let url = document.location.toString();
        let splitHash = url.split("#");
        if (splitHash[1]) {document.getElementById(splitHash[1]).click();}
    };
</script>

what it does is it retrieves the id and fires the click event. Simple.

Stefano Marra

This is my solution to handle nested tabs. I just added a function to check if the active tab has a parent tab to be activated. This is the function:

function activateParentTab(tab) {
    $('.tab-pane').each(function() {
        var cur_tab = $(this);
        if ( $(this).find('#' + tab).length > 0 ) {
            $('.nav-tabs a[href=#'+ cur_tab.attr('id') +']').tab('show');
            return false;
        }
    });
}

And can be called like this (Based on @flynfish's solution):

var hash = document.location.hash;
var prefix = "";
if (hash) {
    $('.nav-tabs a[href='+hash.replace(prefix,"")+']').tab('show');
    activateParentTab(hash);
} 

// Change hash for page-reload
$('.nav-tabs a').on('shown', function (e) {
    window.location.hash = e.target.hash.replace("#", "#" + prefix);
});

This solution works pretty fine to me at the moment. Hope this can be useful for someone else ;)

I had to modify some bits for this to work for me. I am using Bootstrap 3 and jQuery 2

// Javascript to enable link to tab
var hash = document.location.hash;
var prefix = "!";
if (hash) {
    hash = hash.replace(prefix,'');
    var hashPieces = hash.split('?');
    activeTab = $('[role="tablist"] a[href=' + hashPieces[0] + ']');
    activeTab && activeTab.tab('show');
}

// Change hash for page-reload
$('[role="tablist"] a').on('shown.bs.tab', function (e) {
    window.location.hash = e.target.hash.replace("#", "#" + prefix);
});

Great answer, except I had to replace the "!" prefix with "tab_". Otherwise worked perfectly.

I just had this issue, but needed to handle multiple tab levels. The code is rather ugly (see comments), but does its job: https://gist.github.com/JensRantil/4721860 Hopefully someone else will find it useful (and feel free to propose better solutions!).

cweston

Combining peices from other answers, here is a solution that can open many levels of nested tabs:

// opens all tabs down to the specified tab
var hash = location.hash.split('?')[0];
if(hash) {
  var $link = $('[href=' + hash + ']');
  var parents = $link.parents('.tab-pane').get();
  $(parents.reverse()).each(function() {
    $('[href=#' + this.id + ']').tab('show') ;
  });
  $link.tab('show');
}

only works to 2 levels of nesting, the 3rd level causes problems.
I just tested this against three level of tabs, and it appears to be working for me. Are you sure this isn't an issue with your implementation? What "problem" are you experiencing?
Any tab in 1st level and 2nd level works fine, however, in the 3rd level, when refreshing the page (or submitting the form), when the page re-opens, it focus is given to the first tab on the 2nd level.
So got it working ok (there was a minor typo in my code), however after the typo correction, only with $('.nav-tabs li a').click( function(e) { history.pushState( null, null, $(this).attr('href') );}); in the javascript above your code.

I make sth like this for links with ajax #!# (e.g./test.com#!#test3) but you can modify it whatever you like

$(document).ready(function() {

       let hash = document.location.hash;
       let prefix = "!#";

       //change hash url on page reload
       if (hash) {
         $('.nav-tabs a[href=\"'+hash.replace(prefix,"")+'\"]').tab('show');
       } 

       // change hash url on switch tab
       $('.nav-tabs a').on('shown.bs.tab', function (e) {
          window.location.hash = e.target.hash.replace("#", "#" + prefix);
       });
 });

Example with simple page on Github here

Renan Coelho

I know this thread is very old, but I'll leave here my own implementation:

$(function () {
  // some initialization code

  addTabBehavior()
})

// Initialize events and change tab on first page load.
function addTabBehavior() {
  $('.nav-tabs a').on('show.bs.tab', e => {
    window.location.hash = e.target.hash.replace('nav-', '')
  })

  $(window).on('popstate', e => {
    changeTab()
  })

  changeTab()
}

// Change the current tab and URL hash; if don't have any hash
// in URL, so activate the first tab and update the URL hash.
function changeTab() {
  const hash = getUrlHash()

  if (hash) {
    $(`.nav-tabs a[href="#nav-${hash}"]`).tab('show')
  } else {
    $('.nav-tabs a').first().tab('show')
  }
}

// Get the hash from URL. Ex: www.example.com/#tab1
function getUrlHash() {
  return window.location.hash.slice(1)
}

Note that I'm using a nav- class prefix to nav links.
