Preventing scroll when using URI hash to identify tab

This may not be the best method, but if you rename all of the ID's after the tabs have been created, then adding a hash with the original ID won't scroll the page. I used this method because even with javascript disabled, the hash will take the user to the correct ID. Here is a demo of the code below:

$("#tabs").tabs({
    create: function(event, ui) {
        // get tab plugin data
        var tabs = $('#tabs').data('tabs'),
            // tabs.anchors contains all of the tab anchors
            links = tabs.anchors;
        // tabs.panels contains each tab
        tabs.panels.each(function(i){
            // just adding a "mod_" prefix to every ID/hash
            this.id = 'mod_' + this.id;
            links[i].hash = '#' + this.id;
        });
    }
});

/**
 * Add hash to URL of the current page

 * http://stackoverflow.com/questions/570276/changing-location-hash-with-jquery-ui-tabs
 */
$("#tabs").bind('tabsshow', function(event, ui) {
    // remove the prefix from the ID, so we're showing the original ID in the hash
    window.location.hash = ui.tab.hash.replace('mod_', '');
});

As others have mentioned the code from @Mottie might have once worked on older versions of jQuery UI, but this has definitely stopped working. The jQuery UI Tabs api has changed quite a bit since that was written so here is an updated version that works with at least jQuery 1.10.2

Demo here: http://jsfiddle.net/xsx5u5g2/

var $tabs = $("#tabs");
$tabs.tabs({
  create: function(event, ui) {
    // Adjust hashes to not affect URL when clicked.
    var widget = $tabs.data("uiTabs");
    widget.panels.each(function(i){
      this.id = "uiTab_" + this.id; // Prepend a custom string to tab id.
      widget.anchors[i].hash = "#" + this.id;
      $(widget.tabs[i]).attr("aria-controls", this.id);
    });
  },
  activate: function(event, ui) {
    // Add the original "clean" tab id to the URL hash.
    window.location.hash = ui.newPanel.attr("id").replace("uiTab_", "");
  },
});

I'm using jQuery 1.11.1. This workes nicely for me.

$("#tabs").tabs(); //initialize tabs
$(function() {
    $("#tabs").tabs({
        activate: function(event, ui) {
            var scrollTop = $(window).scrollTop(); // save current scroll position
            window.location.hash = ui.newPanel.attr('id'); // add hash to url
            $(window).scrollTop(scrollTop); // keep scroll at current position
        }
    });
});

jQuery UI tabs, update url when clicking on a different tab

Thanks to Jeff B for pointing me here http://jsfiddle.net/jtbowden/ZsUBz/44/

You have to change the window hash without scrolling the page. Here is already a question on SO - Modifying document.location.hash without page scrolling.

The changes required are:

$("#tabs").bind('tabsshow',function(event, ui) {
    setHashWithoutScroll(ui.tab.hash);
});

The setHashWithoutScroll function can be taken from the above mentioned link.

function setHashWithoutScroll(hash) {
    hash = hash.replace( /^#/, '' );
    var fx, node = $( '#' + hash );
    if ( node.length ) {
      node.attr( 'id', '' );
      fx = $( '<div></div>' )
              .css({
                  position:'absolute',
                  visibility:'hidden',
                  top: $(document).scrollTop() + 'px'
              })
              .attr( 'id', hash )
              .appendTo( document.body );
    }
    document.location.hash = hash;
    if ( node.length ) {
      fx.remove();
      node.attr( 'id', hash );
    }
}

The accepted answer throws an error to me - jQuery UI Tabs: Mismatching fragment identifier. So I had to use this one.

I just added the following to my javascript:

    $('#tabs').tabs();
    // Direct links to the tabs, e.g. /my-page#tab-id can cause browsers
    // to scroll down to half-way down the page, which is ugly. We override that here.
    // (This can cause a brief FOUC effect where the page first displays then scrolls up)
    window.scrollTop = '0';
    window.scrollTo(0,0);

In MSIE, I get a brief FOUC effect as the page loads scrolled part-way-down, then flicks to the top.

In Firefox, this works fine without any visible FOUC.

In Chrome, this doesn't work at all -- see scrollTop does not work in Chrome, nor do suggested workarounds

This simple method worked for me:

/* Prevent scroll to tab on click */
$(document).ready(function(){
  $("a.ui-tabs-anchor").click(function(e){
      e.preventDefault();
      return false;
  });
});

I tried @mottie solution but is not working now (2 years after).
It triggers an error: TypeError: tabs is undefined.

Following is an acceptable solution for me:

// preventing scroll
// $("#tabs li a[href^='#tab']").bind('click',function(e){ // less general but better
$("#tabs li a").bind('click',function(e){
    $("html, body").animate({ scrollTop: 0 });
});

There are many answers on this page, and in my mind, most are overcomplicating a simple issue.

Basically, the solution from david-thomas is the simplest and most effective. Essentially, all you want to be doing is preventing the default link behaviour on a tab link (<a> tag).

The same answer applies to the bootstrap tabs, where you have to specify the click handler

   $('.nav-tabs a').click(function(e){
        e.preventDefault();
        $(this).tab('show');
    });
