jquery-tab

Make flat html document that contains title and normal content turns into tab style.

Features

• no link element needed, still search engine friendly for original content
• options help to keep active tab item after page refresh or post back
• name could be used instead of index for individual tab item in some APIs
• vertical label mode
• nested tab
• ARIA support

Usage

html document:

<div class="region">
	<h1>title 1</h1>
	<p>tab 1 content</p>
	<p>another tab 1 content</p>

	<h1>title 2</h1>
	<p>tab 2 content</p>
	<p>another tab 2 content</p>
</div>

javascript code:

$('.region').tab({
	fixedHeight: true
	/*, other options */
});

Generated Html Structure

.region > .tab-container
	> .label-container
		> .label-item
		> .label-item
		> .label-item
		> .label-item
		> ...
	> .panel-container
		> .panel-item
		> .panel-item
		> .panel-item
		> .panel-item
		> ...

label-item and page-item pair is a "tab item".

Including CSS

jquery-tab provides default CSS styles if you don't want to make from scratch. Make sure CSS class name options are not customized.

Importing by module

import 'jquery-tab/dist/theme/gray.css';
import 'jquery-tab/dist/theme/effect/fade.css'; // optional fade effect when switching, must load after theme

Use standalone CSS file

Copying or referencing CSS files from dist/theme/ directory.

Vertical labels

To use vertical labels, specify option mode to "vertical".
Notice that vertical style is implemented by CSS flex features, which means old browsers like IE10-, Chrome 20- and Firefox 27- are not supported.

$('.region').tab({
	mode: 'vertical'
});

Specify options

There are two ways to specify options. By tab() method and by data- attribute.

Specify options by tab() method

Option names are in camel case.

<div class="region">
	......
</div>

$('.region').tab({
	fixedHeight: true
});

Specify options by data- attribute

Option names become html attribute prefixed with data- on region element. Words are always in lower case and separated by -. Only available for primitive option value.

<div data-fixed-height="true" class="region">
	......
</div>

$('.region').tab();

Auto enable jquery-tab

Region containers that has class tab-region will apply jquery-tab plugin automatically.

That would be convenient if using this class name with attribute options. Then no javascript code is needed in most cases:

<div data-fixed-height="true" class="tab-region">
	......
</div>

Deal with individual tab item

Tab item property can be specified as attribute on title element, in lower case, separate words by -, with data- prefixed.

<div class="region">
	<h1 data-tab-item-name="first-item">title 1</h1>
	<p>tab 1 content</p>
	<p>another tab 1 content</p>

	<h1 data-tab-item-disabled="true">title 2</h1>
	<p>tab 2 content</p>
	<p>another tab 2 content</p>
</div>

Supported properties:
tabItemName (data-tab-item-name)
The name should be a non-numeric string, otherwise in controller method parameters, it will be treated as a index.
The name can only contains letters, digits, dashes and underlines.
If names are duplicated in the same tab container, only first item will be recognized.
The logic of getting tab item name could be customized by option fnGetTabItemName.

tabItemDisabled (data-tab-item-disabled)
Specify if this tab item is disabled. A non-false value will be treated as disabled, even for empty string.
The logic of determining if a tab item is disabled could be customized by option fnIsTabItemDisabled.

tabItemHidden (data-tab-item-hidden)
Specify if this tab item is hidden. A non-false value will be treated as hidden, even for empty string.
The logic of determining if a tab item is hidden could be customized by option fnIsTabItemHidden.

Behavior

triggerEvents
Determine the types of events triggered on label-item that will make the panel-item switched. Multiple events can be specified separated by space. Default value is click.

Specify events on label-item that will trigger panel switch after delay a small piece of time. Quite useful if you want to keep hover a little time before switching.

delayTriggerCancelEvents
Specify events on label-item that will cancel delay switching.

keyboardSwitch
Specify if active tab item could be switched by keyboard when label item has focus. If enabled, end user could use arrow keys and Tab key to switch active tab item. Defaults to true.

onBeforeSwitch(from:{index, name}, to:{index, name}, tabState)
A callback before switching the tab. Returns false to cancel a switching attempt. As switching can be happened on initialization, tabState can be used to check. 0 is initializing, and 1 is initialized.

onAfterSwitch(from:{index, name}, to:{index, name}, tabState)
A callback after switching the tab. As switching can be happened on initialization, tabState can be used to check. 0 is initializing, and 1 is initialized.

fnIsTabItemDisabled($title, $content)
Customize the logic of determining if a tab item is disabled when initializing.

Save/Load active position

jquery-tab will load active position by priority of statusFieldSelector, statusHashTemplate, fnLoadPosition and activePosition.

statusHashTemplate
A key-value pair template to store active tab position in URL hash, e.g. tab=.

statusHashSeparator
Specify a separator between multiple hash items if there are more than 1 tab-container store active position in hash on the same page.

fnSavePosition(position)
A callback function to customize how active position is saved, so that this position can be restored in the future, for example when refreshing the page. position could be tab item name or index.

fnLoadPosition
A callback function to customize how active position is loaded. The returned value is either a number/string of number which represents active tab index, or a string represents active tab item name, or a "thenable" object(like jQuery deferred or Promise) which will resolve to a name or index.

activePosition
The default initial active position of the tab. The value is either a number/string of number which represents active tab index, or a string represents active tab item name.
