sw-ui-alert

View as MarkdownOpen in Claude

Modal confirmation / alert dialog primitive built on the native <dialog> element. Resolves a Promise with the user’s choice when used via the companion showPrompt() helper.

1<sw-ui-alert id="confirm" title="Hang up?" confirm-label="Hang up" cancel-label="Stay"></sw-ui-alert>

Two interaction modes are selectable through the reflected type attribute:

  • confirm (default) — renders both Cancel and OK buttons; the returned Promise resolves to true on accept and false on reject / dialog close.
  • alert — renders only OK; the Promise resolves to true once acknowledged or the dialog is dismissed.

The dialog uses the platform <dialog> element so focus management, ESC-to-dismiss, and ::backdrop styling all come for free.
