# jQuery UI Tabs

## Overview

Tabs are generally used to break content into multiple sections that can be swapped to save space, much like an accordion.

By default a tab widget will swap between tabbed sections onClick, but the events can be changed to onHover through an option. Tab content can be loaded via Ajax by setting an href on a tab.

NOTE: Tabs created dynamically using .tabs( "add", ... ) are given an id of ui-tabs-NUM, where NUM is an auto-incrementing id. If you use this naming convention for your own elements, you may encounter problems.

## Events

A series of events fire when interacting with a tabs interface:

- tabsselect, tabsload, tabsshow (in that order)
- tabsadd, tabsremove
- tabsenable, tabsdisable

Event binding example:

    $('#example').bind('tabsselect', function(event, ui) {

        // Objects available in the function context:
        ui.tab     // anchor element of the selected (clicked) tab
        ui.panel   // element, that contains the selected/clicked tab contents
        ui.index   // zero-based index of the selected (clicked) tab

    });

Note that if a handler for the tabsselect event returns false, the clicked tab will not become selected (useful for example if switching to the next tab requires a form validation).

## Ajax mode

Tabs supports loading tab content via Ajax in an unobtrusive manner.

The HTML you need is slightly different from the one that is used for static tabs: A list of links pointing to existing resources (from where the content gets loaded) and no additional containers at all (unobtrusive!). The containers' markup is going to be created on the fly:

    <div id="example">
         <ul>
             <li><a href="ahah_1.html"><span>Content 1</span></a></li>
             <li><a href="ahah_2.html"><span>Content 2</span></a></li>
             <li><a href="ahah_3.html"><span>Content 3</span></a></li>
         </ul>
    </div>

Obviously this degrades gracefully - the links, e.g. the content, will still be accessible with JavaScript disabled.

Note that if you wish to reuse an existing container, you could do so by matching a title attribute and the container's id:

    <li><a href="hello/world.html" title="Todo Overview"> ... </a></li>

and a container like:

    <div id="Todo_Overview"> ... </div>

(Note how white space is replaced with an underscore)

This is useful if you want a human readable hash in the URL instead of a cryptic generated one.

### Back button and bookmarking

Tabs 2 already supported this functionality, although the history plugin needs a rewrite first (it doesn't support Safari 3 and is in general a little inflexible) before it can be build back into the tabs. It is planned and Klaus is working on it whenever he finds the time. Actual bugs in the UI Tabs plugin itself always have higher priority though.

## How to...

### ...retrieve the index of the currently selected tab

    var $tabs = $('#example').tabs();
    var selected = $tabs.tabs('option', 'selected'); // => 0

### ...open links in the current tab instead of leaving the page

"Hijax" links after tab content has been loaded:

    $('#example').tabs({
        load: function(event, ui) {
            $(ui.panel).delegate('a', 'click', function(event) {
                $(ui.panel).load(this.href);
                event.preventDefault();
            });
        }
    });

### ...select a tab from a text link instead of clicking a tab itself

    var $tabs = $('#example').tabs(); // first tab selected

    $('#my-text-link').click(function() { // bind click event to link
        $tabs.tabs('select', 2); // switch to third tab
        return false;
    });

### ...prevent switching to the tab on click depending on form validation

Returning false in the tabs select handler prevents the clicked tab from becoming selected.

    $('#example').tabs({
        select: function(event, ui) {
            var isValid = ... // form validation returning true or false
            return isValid;
        }
    });

### ...immediately select a just added tab

    var $tabs = $('#example').tabs({
        add: function(event, ui) {
            $tabs.tabs('select', '#' + ui.panel.id);
        }
    });

### ...prevent a FOUC (Flash of Unstyled Content) before tabs are initialized

Add the necessary classes to hide an inactive tab panel to the HTML right away - note that this will not degrade gracefully with JavaScript being disabled:

    <div id="example" class="ui-tabs">
      ...
      <div id="a-tab-panel" class="ui-tabs-hide"> </div>
      ...
    </div>

## Why does...

### ...my slider, Google Map, sIFR etc. not work when placed in a hidden (inactive) tab?

Any component that requires some dimensional computation for its initialization won't work in a hidden tab, because the tab panel itself is hidden via `display: none` so that any elements inside won't report their actual width and height (0 in most browsers).

There's an easy workaround. Use the off-left technique for hiding inactive tab panels. E.g. in your style sheet replace the rule for the class selector ".ui-tabs .ui-tabs-hide" with

    .ui-tabs .ui-tabs-hide {
        position: absolute;
        left: -10000px;
    }

For Google maps you can also resize the map once the tab is displayed like this:

    $('#example').bind('tabsshow', function(event, ui) {
        if (ui.panel.id == "map-tab") {
            resizeMap();
        }
    });

resizeMap() will call Google Maps' checkResize() on the particular map.

        $( ".selector" ).tabs({ disabled: true });

  Get or set the `disabled` option, after init.

        //getter
        var disabled = $( ".selector" ).tabs( "option", "disabled" );
        //setter
        $( ".selector" ).tabs( "option", "disabled", true );

- ### ajaxOptions

  Type:
    Options
  Default:
    null

  Additional Ajax options to consider when loading tab content (see $.ajax).

  #### Code examples

  Default:
    false

  Whether or not to cache remote tabs content, e.g. load only once or with every click. Cached content is being lazy loaded, e.g once and only once for the first click. Note that to prevent the actual Ajax requests from being cached by the browser you need to provide an extra cache: false flag to ajaxOptions.

The second argument is either a URL consisting of a fragment identifier only to create an in-page tab or a full url (relative or absolute, no cross-domain support) to turn the new tab into an Ajax (remote) tab. The third is the zero-based position where to insert the new tab. Optional, by default a new tab is appended at the end.

- ### remove

  Signature:
    .tabs( "remove" , index )

  Remove a tab. The second argument is the zero-based index of the tab to be removed. Instead of an index, the href of the tab may be passed.

- ### enable

  Signature:
    .tabs( "enable" , index )

  Enable a disabled tab. To enable more than one tab at once reset the disabled property like: `$('#example').tabs("option","disabled",[]);`. The second argument is the zero-based index of the tab to be enabled. Instead of an index, the href of the tab may be passed.

- ### disable

  Signature:
    .tabs( "disable" , index )

  Disable a tab. The selected tab cannot be disabled. To disable more than one tab at once use: `$('#example').tabs("option","disabled", [1, 2, 3]);` The second argument is the zero-based index of the tab to be disabled. Instead of an index, the href of the tab may be passed.

- ### select

  Signature:
    .tabs( "select" , index )

  Select a tab, as if it were clicked. The second argument is the zero-based index of the tab to be selected or the id selector of the panel the tab is associated with (the tab's href fragment identifier, e.g. hash, points to the panel's id).

- ### load

  Signature:
    .tabs( "load" , index )

  Reload the content of an Ajax tab programmatically. This method always loads the tab content from the remote location, even if cache is set to true. The second argument is the zero-based index of the tab to be reloaded.

- ### url

  Signature:
    .tabs( "url" , index , url )

  Change the url from which an Ajax (remote) tab will be loaded. The specified URL will be used for subsequent loads. Note that you can not only change the URL for an existing remote tab with this method, but also turn an in-page tab into a remote tab. The second argument is the zero-based index of the tab of which its URL is to be updated. The third is a URL the content of the tab is loaded from.

- ### length

  Signature:
    .tabs( "length" )

  Retrieve the number of tabs of the first matched tab pane.

- ### abort

  Signature:
    .tabs( "abort" )

  Terminate all running tab ajax requests and animations.

- ### rotate

  Signature:
    .tabs( "rotate" , ms , [continuing] )

The third controls whether or not to continue the rotation after a tab has been selected by a user. Default: false.

## Theming

The jQuery UI Tabs plugin uses the jQuery UI CSS Framework to style its look and feel, including colors and background textures. We recommend using the ThemeRoller tool to create and download custom themes that are easy to build and maintain.

If a deeper level of customization is needed, there are widget-specific classes referenced within the jquery.ui.tabs.css stylesheet that can be modified. These classes are highlighed in bold below.

### Sample markup with jQuery UI CSS Framework classes

<div id="tabs">
<ul>
<li><a href="#tabs-1">Nunc tincidunt</a></li>
<li><a href="#tabs-2">Proin dolor</a></li>
<li><a href="#tabs-3">Aenean lacinia</a></li>
</ul>
<div id="tabs-1">
<p>Tab 1 content</p>
</div>
<div id="tabs-2">
<p>Tab 2 content</p>
</div>
<div id="tabs-3">
<p>Tab 3 content</p>
</div>
</div>.
