JET Custom Elements

JET components are implemented as custom HTML elements. In addition to the component attributes documented in this page, JET components also support standard HTML global attributes like id and aria-label.

The JET data binding syntax can be used to define both component and global attributes through the use of dynamically evaluated expressions. All attributes (component and global) support attribute-level binding by prefixing the attribute name with ":" (e.g. :id="[...]"). When using attribute-level binding, all expression values are treated as strings. Additionally, component attributes support property-level binding by using the attribute name directly with no ":" prefix. When using property-level binding, the expressions should evaluate to the types documented by the corresponding attributes. Property-level binding is strongly recommended over attribute-level binding for component attributes.

A detailed description of working with custom HTML elements can be found in: JET Custom Element Usage.

JET Avatar

Description: Themeable, WAI-ARIA-compliant element that often represents a person.

A JET avatar is an icon capable of displaying a custom image, or initials, or a placeholder image. The order of precedence for what is displayed, in order from highest to lowest, is:

  1. Custom image specified through the "src" attribute
  2. Initials specified through the "initials" attribute
  3. Default placeholder image
//Avatar with initials
<oj-avatar initials="AB">


If the application sets the role of oj-avatar to 'img' aria-label must be set for accessibility purposes. JET Avatar does not have any interaction with the application, therefore it is not keyboard navigable by default. The aria-label will be picked up by the tabbable/focusable parent unless it is overriden by the application. The application can set a tooltip by setting the title attribute of the avatar. It is recommended that the title and aria-label attributes are in sync.

In order to meet accessibility requirements for text, color contrast ratio between the background color and text must be greater than 4.5 for the two smallest avatars and 3.1 for the five larger avatars. Avatar's default background satisfies the 3.1 color contrast ratio. The background will automatically be darkened for the two smallest sizes to satisfy the more stringent 4.5 contrast ratio. If colors are customized through theming, the application is responsible for specifying colors that satisfy the 3.1 contrast ratio. The custom background color will be automatically darkened as well for the two smallest avatars.

The src attribute will display the image as a background-image. These images do not appear in high contrast mode. For this reason, initials must be specified and and will be shown instead.


The avatar will display the image provided from the src attribute if the src attribute is populated. If the src attribute is not provided and the initials have been, the initials will be displayed. If neither src nor initials attributes are populated, a single person placeholder image is shown. Use the class oj-avatar-group-image to use the group placeholder image. Examples displaying each type of avatar:

//Individual Placeholder
//Group Placeholder
<oj-avatar class="oj-avatar-group-image">
<oj-avatar initials="AB">
<oj-avatar initials="AB" src="image.jpg">


The following CSS classes can be applied by the page author as needed.

Class Description
oj-avatar-group-image Use to diplay avatar group placeholder image instead of single person placeholder image.

Note: Application logic should not interact with the component's properties or invoke its methods until the BusyContext indicates that the component is ready for interaction.
