States

In addition to the variant, <sp-buttons> have a disabled state visual state which can be applied by adding the attribute disabled. All spectrum-button variants support the In addition to affectng the visual state, the disabled attribute prevents focus and disallows click events.

<sp-button-group>
    <sp-button variant="primary">Normal</sp-button>
    <sp-button variant="primary" disabled>Disabled</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>

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>
