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

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

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

Initialize the button with the disabled option specified:

icons 

Type: 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" }.
