useHash

Read and write URL hash.

Import

import { useHash } from '@tidbcloud/uikit'

Usage

useHash returns hash from URL, subscribes to its changes with the hashchange event, and allows changing it with setHash function.

import { useHash } from '@tidbcloud/uikit'
import { Button, Text, Group } from '@tidbcloud/uikit'
 
function Demo() {
  const [hash, setHash] = useHash()
 
  return (
    <>
      <Text>Current hash: {hash || 'none'}</Text>
      <Group>
        <Button onClick={() => setHash('section-1')}>Go to section 1</Button>
        <Button onClick={() => setHash('section-2')}>Go to section 2</Button>
      </Group>
    </>
  )
}

Initial State Value

By default, useHash retrieves value in useEffect. If you want to get the initial value immediately:

import { useHash } from '@tidbcloud/uikit'
 
const [hash, setHash] = useHash({ getInitialValueInEffect: false })

Note: This option is not compatible with server-side rendering.

Definition

interface UseHashOptions {
  getInitialValueInEffect?: boolean
}
 
type UseHashReturnValue = [string, (value: string) => void]
 
function useHash(options?: UseHashOptions): UseHashReturnValue
