If true, the modal will be open.
Alert Dialog
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#
AlertDialoghas rolealertdialog, andaria-modalset to true.- When the dialog opens, focus is automatically set to the least destructive element.
- When the dialog opens, the content in the
AlertDialogHeaderandAlertDialogBodyare announced by screen readers viaaria-labelledbyandaria-describedbyattributes. - 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.

This is useful in situations where you still need to interact with
other surrounding elements.

accessibility of the modal, based on WAI-ARIA specifications.
