or tapped to perform an action or to navigate to another page. sp-buttons in
Spectrum have several variations for different uses and multiple levels of
loudness for various attention-getting needs.

States
In addition to the variant, <sp-button>
elements support two different visual states, disabled and pending, which can be applied by adding the attribute disabled
or pending
respectively. All <sp-button>
variants support these states.
Disabled
While disabled, <sp-button>
elements will not respond to click events and will appear faded.
<sp-button-group>
<sp-button variant="primary">Normal</sp-button>
<sp-button variant="primary" disabled>Disabled</sp-button>
</sp-button-group>
Pending
While in pending state, <sp-button>
elements will not respond to click events and will appear faded with an indeterminent <sp-progress-circle>
.
<sp-button>
elements label and icon will be hidden while in pending state.
Note: pending
state of the <sp-button>
element is applied after 1s delay to avoid flashing the pending state for quick actions.
You can override the delay by adding custom css var --pending-delay
to your css.
<sp-button-group>
<sp-button variant="primary">Normal</sp-button>
<sp-button variant="primary" pending>Pending</sp-button>
</sp-button-group>
Handling events
Events handlers for clicks and other user actions can be registered on a
<sp-button>
as on a standard HTML <button>
element.
<sp-button onclick="spAlert(this, '<sp-button> clicked!')">Click me</sp-button>
In addition to handling events like a native <button>
HTML element, one can also use a <sp-button>
in place of the <a>
element by using the href
and optional target
attribute.
<sp-button
href="https://github.com/adobe/spectrum-web-components"
target="_blank"
>
Click me
</sp-button>
Autofocus
The autofocus
attribute sets focus to the <sp-button>
when the component
mounts. This is useful for setting focus to a specific sp-button when a
popover or dialog opens.
<sp-button autofocus>Confirm</sp-button>
