# jQuery UI Button

## Overview

Button enhances standard form elements like button, input of type submit or reset or anchors to themable buttons with appropiate mouseover 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.

In order to group radio buttons, Button also provides an additional widget-method, called Buttonset. Its 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 descendents and applying button() to them. You can enable and disable a buttonset, which will enable and disable all contained buttons. Destroying a buttonset also calls the button's destroy method.

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

## Options

- ### disabled

  #### Code examples

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

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

        //getter
        var disabled = $( ".selector" ).button( "option", "disabled" );

        $( ".selector" ).button( "option", "disabled", true );

- ### text

  Type:
    Boolean
  Default:
    true

  Whether to show any text - when set to false (display no text), icons (see icons option) must be enabled, otherwise it'll be ignored.

  #### Code examples

## Theming

The jQuery UI Button 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.button.css stylesheet that can be modified. These classes are highlighed in bold below.

### Sample markup with jQuery UI CSS Framework classes

<button class="ui-button ui-button-text-only ui-widget ui-state-default ui-corner-all">
<span class="ui-button-text">Button Label</span>
</button>

Note: This is a sample of markup generated by the button plugin, not markup you should use to create a button. The only markup needed for that is <button>Button Label</button>.
