Whether the item is active.
Whether the item is disabled.
Whether the item is selected.
The current value of the item. If not specified, the element's text content is used.
Invoked when the component is added to the document's DOM.
In connectedCallback()
you should setup tasks that should only occur when
the element is connected to the document. The most common of these is
adding event listeners to nodes external to the element, like a keydown
event handler added to the window.
connectedCallback() {
super.connectedCallback();
addEventListener('keydown', this._handleKeydown);
}
Typically, anything done in connectedCallback()
should be undone when the
element is disconnected, in disconnectedCallback()
.
Static
stylesArray 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>
