## Button Widget version added: 1.8

Description: Themable buttons and button sets.

## QuickNavExamples

Button enhances standard form elements like buttons, inputs and anchors to themable buttons with appropiate hover and active styles.

In addition to basic push buttons, radio buttons and checkboxes (inputs of type radio and checkbox) can be converted to buttons. Their associated label is styled to appear as the button, while the underlying input is updated on click. For the association to work properly, give the input an `id` attribute, and refer to that in the label's `for` attribute. Don't nest the input inside the label, as that causes accessbility problems.

In order to group radio buttons, Button also provides an additional widget, called Buttonset. Buttonset is used by selecting a container element (which contains the radio buttons) and calling `.buttonset()`. Buttonset will also provide visual grouping, and therefore should be used whenever you have a group of buttons. It works by selecting all descendants and applying `.button()` to them. You can enable and disable a button set, which will enable and disable all contained buttons. Destroying a button set also calls each button's `destroy` method.

When using an input of type button, submit or reset, support is limited to plain text labels with no icons.

### Dependencies

- UI Core
- Widget Factory

### Additional Notes:

- This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.

## Options

### disabledType: Boolean

Default: `false`
Disables the button if set to `true`.
Code examples:

Initialize the button with the `disabled` option specified:

1

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

Get or set the `disabled` option, after initialization:

1
2
3
4
5

    // gettervar disabled = $( ".selector" ).button( "option", "disabled" ); // setter$( ".selector" ).button( "option", "disabled", true );

### iconsType: Object

Default: `{ primary: null, secondary: null }`
Icons to display, with or without text (see `text` option). By default, the primary icon is displayed on the left of the label text and the secondary is displayed on the right. The positioning can be controlled via CSS. The value for the `primary` and `secondary` properties must be a class name, e.g., `"ui-icon-gear"`. For using only one icon: `icons: { primary: "ui-icon-locked" }`. For using two icons: `icons: { primary: "ui-icon-gear", secondary: "ui-icon-triangle-1-s" }`.
Code examples:

Initialize the button with the `icons` option specified:

1

    $( ".selector" ).button({ icons: { primary: "ui-icon-gear", secondary: "ui-icon-triangle-1-s" } });

Get or set the `icons` option, after initialization:

1

    // gettervar icons = $( ".selector" ).button( "option", "icons" ); // setter$( ".selector" ).button( "option", "icons", { primary: "ui-icon-gear", secondary: "ui-icon-triangle-1-s" } );

### labelType: String

Default: `null`
Text to show in the button. When not specified (`null`), the element's HTML content is used, or its `value` attribute if the element is an input element of type submit or reset, or the HTML content of the associated label element if the element is an input of type radio or checkbox.
Code examples:

Initialize the button with the `label` option specified:

1

    $( ".selector" ).button({ label: "custom label" });

Get or set the `label` option, after initialization:

1
2

    // gettervar label = $( ".selector" ).button( "option", "label" ); // setter$( ".selector" ).button( "option", "label", "custom label" );

### textType: Boolean

Default: `true`
Whether to show the label. When set to `false` no text will be displayed, but the `icons` option must be enabled, otherwise the `text` option will be ignored.
Code examples:

Initialize the button with the `text` option specified:

1

    $( ".selector" ).button({ text: false });

Get or set the `text` option, after initialization:

1
