在 ref 中表示组件是否已挂载。

示例

源码playground (beta)

unmounted

使用方法

import { useMounted } from '@vueuse/core'

const isMounted = useMounted()

这本质上相当于：

const isMounted = ref(false)

onMounted(() => {
  isMounted.value = true
})

类型声明

/**
 * Mounted state in ref.
 *
 * @see https://vueuse.org/useMounted
 *
 * @__NO_SIDE_EFFECTS__
 */
export declare function useMounted(): ShallowRef<boolean, boolean>
