Creates a basic button.
By default, the button renders the contents of its direct children (i.e. it has a single unnamed <slot>).
Subclasses can override this by overriding render.
Optionaloptions: ButtonOptionsProtected_Whether this radio button is checked.
Whether the button is disabled.
When disabled, the button cannot be clicked.
The lang property of the HTMLElement interface indicates the base language of an element's attribute values and text content, in the form of a BCP 47 language tag. It reflects the element's lang attribute; the xml:lang attribute does not affect this property.
The value associated with this radio button.
Protected Readonly_Protected Readonly_ProtectedhandleProtectedhandleHandle a button click.
By default, this does nothing. Subclasses can override this method to add behavior to the button.
ProtectedhandleProtectedrenderInvoked when the component is removed from the document's DOM.
This callback is the main signal to the element that it may no longer be
used. disconnectedCallback() should ensure that nothing is holding a
reference to the element (such as event listeners added to nodes external
to the element), so that it is free to be garbage collected.
disconnectedCallback() {
super.disconnectedCallback();
window.removeEventListener('keydown', this._handleKeydown);
}
An element may be re-connected after being disconnected.
StaticstylesArray of styles to apply to the element. The styles should be defined
using the css tag function, via constructible stylesheets, or
imported from native CSS module scripts.
Note on Content Security Policy:
Element styles are implemented with <style> tags when the browser doesn't
support adopted StyleSheets. To use such <style> tags with the style-src
CSP directive, the style-src value must either include 'unsafe-inline' or
nonce-<base64-value> with <base64-value> replaced be a server-generated
nonce.
To provide a nonce to use on generated <style> elements, set
window.litNonce to a server-generated nonce in your page's HTML, before
loading application code:
<script>
// Generated and unique per request:
window.litNonce = 'a1b2c3d4';
</script>
