Confirm Modals
Use a confirm modal to ask users to respond before they continue. To display a confirm modal in Lightning Experience, import LightningConfirm from the lightning/confirm module, and call LightningConfirm.open() with your desired attributes.
This confirm modal is an alternative to the native window.confirm() function, which isn’t supported for cross-origin iframes in Chrome and Safari. Unlike the native confirm function, LightningConfirm.open() doesn't halt execution on the page, it returns a Promise. Use async/await or .then() for any code you want to execute after the modal is closed.
This example component creates a button that opens the confirm modal UI that you see in the screenshot.
Import LightningConfirm from lightning/confirm in the JavaScript file of the component that opens the confirm modal. Create and dispatch a LightningConfirm event with message, variant, and label attributes. The .open() function returns a promise that resolves to true when you click OK and false when you click Cancel.
For information about the attributes for the confirm modal, see the Component Reference.
