JqueryUI - Tabs

Tabs are sets of logically grouped content that allow us to quickly flip between them to. Tabs allow us to save space like accordions. For tabs to work properly following set of markups needs to use −

  • Tabs must be in a list either ordered(<ol>) or unordered(<ul>).

  • Each tab title must be within each <li> and wrapped by anchor (<a>) tag with an href attribute.

  • Each tab panel may be any valid element but it must have an id, which corresponds to the hash in the anchor of the associated tab.

jQueryUI provides us tabs () method drastically changes the appearance of HTML elements inside the page. This method traverses (internally in jQuery UI) HTML code and adds new CSS classes to the elements concerned (here, the tabs) to give them the appropriate style.

Syntax

The tabs () method can be used in two forms −

$ (selector, context).tabs (options) Method

The tabs (options) method declares that an HTML element and its content should be managed as tabs. The options parameter is an object that specifies the appearance and behavior of tabs.

Syntax

$(selector, context).tabs (options);

You can provide one or more options at a time using JavaScript object. If there are more than one options to be provided then you will separate them using a comma as follows −

$(selector, context).tabs({option1: value1, option2: value2..... });

The following table lists the different options that can be used with this method −

Sr.No. Option & Description
1 active

This option specifies the current active tab/panel. By default its value is 0.

Option - active

This option specifies the current active tab/panel. By default its value is 0.

This can be of type −

  • Boolean − When set to false, will collapse all the panels. This requires the collapsible option to be true.

  • Integer −

    The zero-based index of the panel that is active (open). A negative value selects panels going backward from the last panel.

Syntax

$( ".selector" ).tabs (
   { active: 1 }
);
2 collapsible

This option set to true, it allows tabs to be deselected. When set to false (the default), clicking on a selected tab does not deselect (it remains selected). By default its value is false.

Option - collapsible

This option set to true, it allows tabs to be deselected. When set to false (the default), clicking on a selected tab does not deselect (it remains selected). By default its value is false.

Syntax

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

This option uses an array to indicate index tabs that are disabled (and therefore cannot be selected). For example, use [0, 1] to disable the first two tabs. By default its value is false.

Option - disabled

This option uses an array to indicate index tabs that are disabled (and therefore cannot be selected). For example, use [0, 1] to disable the first two tabs. By default its value is false.

This can be of type −

  • Boolean − Enable or disable all tabs.

  • Array − An array containing the zero-based indexes of the tabs that should be disabled, e.g., [ 0, 2 ] would disable the first and third tab.

Syntax

$( ".selector" ).tabs (
   { disabled: [ 0, 2 ] }
);
4 event

This option is a name of the event that lets users select a new tab. If, for example, this option is set to "mouseover", passing the mouse over a tab will select it. By default its value is "click".

Option - event

This option is a name of the event that lets users select a new tab. If, for example, this option is set to "mouseover", passing the mouse over a tab will select it. By default its value is "click".

Syntax

$( ".selector" ).tabs (
   { event: "mouseover" }
);
5 heightStyle

This option controls the height of the tabs widget and each panel. By default its value is "content".

Option - heightStyle

This option controls the height of the tabs widget and each panel. By default its value is "content".

Possible values are −

  • auto − All panels will be set to the height of the tallest panel.

  • fill − Expand to the available height based on the tabs' parent height.

  • content − Each panel will be only as tall as its content.

Syntax

$( ".selector" ).tabs (
   { heightStyle: "fill" }
);
6 hide

This option specifies how to animate hiding of panel. By default its value is null.

Option - hide

This option specifies how to animate hiding of panel. By default its value is null.

This can be of type −

  • Boolean − When set to false, no animation will be used and the panel will be hidden immediately.

  • Number − The panel will fade out with the specified duration and the default easing.

  • String − The panel will be hidden using the specified effect. Value can be slideUp or fold

  • Object − For this type, properties effect, delay, duration and easing may be provided.

Syntax

$( ".selector" ).tabs (
   { { hide: { effect: "explode", duration: 1000 } } }
);
7 show

This option specifies how to animate showing of panel. By default its value is null.

Option - show

This option specifies how to animate showing of panel. By default its value is null.

This can be of type −

  • Boolean − When set to false, no animation will be used and the panel will be shown immediately.

  • Number − The panel will fade out with the specified duration and the default easing.

  • String − The panel will be shown using the specified effect. Value can be slideUp or fold.

  • Object − For this type, properties effect, delay, duration and easing may be provided.

Syntax

$( ".selector" ).tabs (
   { show: { effect: "blind", duration: 800 } }
);

The following section will show you a few working examples of tabs functionality.

Default Functionality

The following example demonstrates a simple example of tabs functionality, passing no parameters to the tabs() method.

In the above example toggle the sections open/closed with mouseover the tabs.

$ (selector, context).tabs ("action", params) Method

The tabs ("action", params) method allows an action on the tabs (through a JavaScript program), selecting, disabling, adding, or removing a tab. The action is specified as a string in the first argument (e.g., "add" to add a new tab). Check out the actions that can be passed, in the following table.

Let us save the above code in an HTML file tabsexample.htm and open it in a standard browser which supports javascript, you should see the following output −

In the above example, you notice that Tab 3 is disabled.
