Content

<sp-button> elements can be provided a visible label, a label with an icon, or just an icon (a non-visible label can be prived via the label attribute on an <sp-button> or on an <sp-icon*> element child to appropriately fulfill the accessibility contract of the button). An icon is provided by placing an icon element to the icon slot.

</sp-button-group>

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>
