import {
  AlertDialog,
  AlertDialogBody,
  AlertDialogFooter,
  AlertDialogHeader,
  AlertDialogContent,
  AlertDialogOverlay,
} from "@chakra-ui/core";

import {
  AlertDialog,
  AlertDialogBody,
  AlertDialogFooter,
  AlertDialogHeader,
  AlertDialogContent,
  AlertDialogOverlay,
} from "@chakra-ui/core";

Usage#

AlertDialog requires that you provide the leastDestructiveRef prop.

Based on WAI-ARIA specifications, focus should be placed on the least destructive element when the dialog opens, to prevent users from accidentally confirming the destructive action.

function AlertDialogExample() {
  const [isOpen, setIsOpen] = React.useState();
  const onClose = () => setIsOpen(false);
  const cancelRef = React.useRef();

  return (
    <>
      <Button variantColor="red" onClick={() => setIsOpen(true)}>
        Delete Customer
      </Button>

      <AlertDialog
        isOpen={isOpen}
        leastDestructiveRef={cancelRef}
        onClose={onClose}
      >
        <AlertDialogOverlay />
        <AlertDialogContent>
          <AlertDialogHeader fontSize="lg" fontWeight="bold">
            Delete Customer
          </AlertDialogHeader>

          <AlertDialogBody>
            Are you sure? You can't undo this action afterwards.
          </AlertDialogBody>

          <AlertDialogFooter>
            <Button ref={cancelRef} onClick={onClose}>
              Cancel
            </Button>
            <Button variantColor="red" onClick={onClose} ml={3}>
              Delete
            </Button>
          </AlertDialogFooter>
        </AlertDialogContent>
      </AlertDialog>
    </>
  );
}

function AlertDialogExample() {
  const [isOpen, setIsOpen] = React.useState();
  const onClose = () => setIsOpen(false);
  const cancelRef = React.useRef();
  return (
    <>
      <Button variantColor="red" onClick={() => setIsOpen(true)}>
        Delete Customer
      </Button>
      <AlertDialog
        isOpen={isOpen}
        leastDestructiveRef={cancelRef}
        onClose={onClose}
      >
        <AlertDialogOverlay />
        <AlertDialogContent>
          <AlertDialogHeader fontSize="lg" fontWeight="bold">
            Delete Customer
          </AlertDialogHeader>
          <AlertDialogBody>
            Are you sure? You can't undo this action afterwards.
          </AlertDialogBody>
          <AlertDialogFooter>
            <Button ref={cancelRef} onClick={onClose}>
              Cancel
            </Button>
            <Button variantColor="red" onClick={onClose} ml={3}>
              Delete
            </Button>
          </AlertDialogFooter>
        </AlertDialogContent>
      </AlertDialog>
    </>
  );
}

Adding transition#

The modal doesn't come with any transition by default so you can manage this yourself. Chakra exports two transition components SlideIn and Scale to provide simple transitions.

For some reason, focus doesn't return back to the trigger after the transition ends. As a walkaround, you might need to set finalFocusRef to the trigger or any other element, and set isOpen to true.

function TransitionExample() {
  const { isOpen, onOpen, onClose } = useDisclosure();
  const btnRef = React.useRef();
  const cancelRef = React.useRef();

  return (
    <>
      <Button ref={btnRef} onClick={onOpen}>
        Discard
      </Button>
      {/* You can swap the `Scale` with `SlideIn` to see a different transition */}
      <Scale in={isOpen}>
        {styles => (
          <AlertDialog
            leastDestructiveRef={cancelRef}
            finalFocusRef={btnRef}
            onClose={onClose}
            isOpen={true}
          >
            <AlertDialogOverlay opacity={styles.opacity} />
            <AlertDialogContent {...styles}>
              <AlertDialogHeader>Discard Changes?</AlertDialogHeader>
              <AlertDialogCloseButton />
              <AlertDialogBody>
                Are you sure you want to discard all of your notes? 44 words
                will be deleted.
              </AlertDialogBody>
              <AlertDialogFooter>
                <Button ref={cancelRef} onClick={onClose}>
                  No
                </Button>
                <Button variantColor="red" ml={3}>
                  Yes
                </Button>
              </AlertDialogFooter>
            </AlertDialogContent>
          </AlertDialog>
        )}
      </Scale>
    </>
  );
}

function TransitionExample() {
  const { isOpen, onOpen, onClose } = useDisclosure();
  const btnRef = React.useRef();
  const cancelRef = React.useRef();
  return (
    <>
      <Button ref={btnRef} onClick={onOpen}>
        Discard
      </Button>
      {/* You can swap the `Scale` with `SlideIn` to see a different transition */}
      <Scale in={isOpen}>
        {styles => (
          <AlertDialog
            leastDestructiveRef={cancelRef}
            finalFocusRef={btnRef}
            onClose={onClose}
            isOpen={true}
          >
            <AlertDialogOverlay opacity={styles.opacity} />
            <AlertDialogContent {...styles}>
              <AlertDialogHeader>Discard Changes?</AlertDialogHeader>
              <AlertDialogCloseButton />
              <AlertDialogBody>
                Are you sure you want to discard all of your notes? 44 words
                will be deleted.
              </AlertDialogBody>
              <AlertDialogFooter>
                <Button ref={cancelRef} onClick={onClose}>
                  No
                </Button>
                <Button variantColor="red" ml={3}>
                  Yes
                </Button>
              </AlertDialogFooter>
            </AlertDialogContent>
          </AlertDialog>
        )}
      </Scale>
    </>
  );
}
