AlertDialog
component is used to interrupt the user with a mandatory confirmation or action.
Import#
Chakra UI exports 7 alert dialog related components.
AlertDialog
: provides context and state for the dialog.AlertDialogHeader
: should contain the title announced by screen readers.AlertDialogBody
: should contain the description announced by screen readers.AlertDialogFooter
: should contain the actions of the dialog.AlertDialogOverlay
: The dimmed overlay behind the dialog.AlertDialogContent
: The wrapper for the alert dialog's content.AlertDialogCloseButton
: The button that closes the dialog.
import {AlertDialog,AlertDialogBody,AlertDialogFooter,AlertDialogHeader,AlertDialogContent,AlertDialogOverlay,} from '@chakra-ui/react';
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, onOpen, onClose } = useDisclosure();const cancelRef = React.useRef();return (<><Button colorScheme="red" onClick={onOpen}>Delete Customer</Button><AlertDialogisOpen={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 colorScheme="red" onClick={onClose} ml={3}>Delete</Button></AlertDialogFooter></AlertDialogContent></AlertDialogOverlay></AlertDialog></>);}
Changing the transition#
The Modal
comes with a scale transition by default but you can change it by passing a motionPreset
prop, and set its value to either slideInBottom
, slideInRight
, or scale
.
function TransitionExample() {const { isOpen, onOpen, onClose } = useDisclosure();const cancelRef = React.useRef();return (<><Button onClick={onOpen}>Discard</Button><AlertDialogmotionPreset="slideInBottom"leastDestructiveRef={cancelRef}onClose={onClose}isOpen={isOpen}isCentered><AlertDialogOverlay /><AlertDialogContent><AlertDialogHeader>Discard Changes?</AlertDialogHeader><AlertDialogCloseButton /><AlertDialogBody>Are you sure you want to discard all of your notes? 44 words will bedeleted.</AlertDialogBody><AlertDialogFooter><Button ref={cancelRef} onClick={onClose}>No</Button><Button colorScheme="red" ml={3}>Yes</Button></AlertDialogFooter></AlertDialogContent></AlertDialog></>);}
Accessibility#
AlertDialog
has rolealertdialog
, andaria-modal
set to true.- When the dialog opens, focus is automatically set to the least destructive element.
- When the dialog opens, the content in the
AlertDialogHeader
andAlertDialogBody
are announced by screen readers viaaria-labelledby
andaria-describedby
attributes. - Clicking on the overlay closes the
AlertDialog
. - Pressing esc closes the dialog.
Props#
AlertDialog
and its components compose the Modal
component. The only exception is that it requires a leastDestructiveRef
which is similar to the initialFocusRef
of Modal
