JET Button

Description: Themeable, WAI-ARIA-compliant push buttons, with appropriate styles for hover, active, and disabled. 

<oj-c-button id="myButton" label="My Button">
</oj-c-button>
<oj-c-button label="start icon">
  <span slot='startIcon' class='myIconClass'></span>

Push Buttons

Push buttons are ordinary buttons that do not stay pressed in when clicked. Push buttons are created from oj-c-button elements.

Touch End User Information

Keyboard End User Information

Target Key Action
Push Button Enter or Space Push the button.

Accessibility

For accessibility, it is not required to set an aria label on a JET button as it uses the label text to generate an aria label. Therefore the label should be specified even if the button is icon-only (display=icons). However, you can override the default behavior by setting aria-label. The label can be hidden using the display attribute.

Disabled content: JET supports an accessible luminosity contrast ratio, as specified in WCAG 2.0 - Section 1.4.3 "Contrast", in the themes that are accessible. (See the "Theming" chapter of the JET Developer Guide for more information on which themes are accessible.) Note that Section 1.4.3 says that text or images of text that are part of an inactive user interface component have no contrast requirement. Because disabled content may not meet the minimum contrast ratio required of enabled content, it cannot be used to convey meaningful information.

Slots

JET components that allow child content support slots. Please see the slots section of the JET component overview doc for more information on allowed slot content and slot types.

endIcon

The endIcon slot is the button's end icon. The oj-c-button element accepts DOM nodes as children with the endIcon slot.

startIcon

The startIcon slot is the button's start icon. The oj-c-button element accepts DOM nodes as children with the startIcon slot.

Attributes

chroming :"ghost"|"borderless"|"outlined"|"solid"|"callToAction"|"danger"

Indicates in what states the button has variants in background and border.
Supported Values:
Value Description
borderless Borderless buttons are a more prominent variation. Borderless buttons are useful for supplemental actions that require minimal emphasis.
callToAction A Call To Action (CTA) button guides the user to take or complete the action that is the main goal of the page or page section. There should only be one CTA button on a page at any given time.
danger A Danger button alerts the user to a dangerous situation.
