Import the side effectful registration of <sp-clear-button> as follows:

import '@spectrum-web-components/button/sp-clear-button.js';

When looking to leverage the ClearButton base class as a type and/or for extension purposes, do so via:

import { ClearButton } from '@spectrum-web-components/button';

Anatomy

The clear button is a button with only close icon.

<sp-clear-button>Reset</sp-clear-button>

Label

The label for an <sp-clear-button> element can be set via it's default slot or with the label attribute. With either method, the label will not be visible but still read by screen readers.

Default slot Label attribute 
<sp-clear-button label="Clear">Clear</sp-clear-button>

Options

Sizes

Small Medium 
<sp-clear-button size="m">Medium</sp-clear-button>
 Large Extra Large

States

In addition to the variant, the <sp-clear-button> elements supports a disabled state, which can be applied by adding the attribute disabled.

Disabled

While disabled, the <sp-clear-button> element will not respond to click events and will appear faded.

<sp-button-group>
    <sp-clear-button>Normal</sp-clear-button>
    <sp-clear-button disabled>Disabled</sp-clear-button>
</sp-button-group>

Behaviors

Handling events

Events handlers for clicks and other user actions can be registered on a <sp-clear-button> as one would on a standard HTML <button> element.

<sp-clear-button onclick="spAlert(this, '<sp-clear-button> clicked!')">
    Click me
</sp-clear-button>

Autofocus

The autofocus attribute sets focus on the <sp-clear-button> when the component mounts. This is useful for setting focus to a specific sp-clear-button when a popover or dialog opens.

<sp-button id="trigger">Open</sp-button>
<sp-overlay trigger="trigger@click" placement="bottom">
    <sp-popover>
        <!-- Button will autofocus when open -->
        <sp-clear-button autofocus>Clear</sp-clear-button>
    </sp-popover>
</sp-overlay>

Accessibility

Include a label

A button is required to have either text in the default slot or a label attribute on the <sp-clear-button>.
