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
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);
});
});
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.
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.
$(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.
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');
}
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);
});
