示例

source

For demonstration purpose, the idle timeout is set to 5s in this demo (default 1min).

Idle: false

Inactive: 0s

用法

¥Usage

import { useIdle } from '@vueuse/core'

const { idle, lastActive } = useIdle(5 * 60 * 1000) // 5 min

console.log(idle.value) // true or false

以编程方式重置：

¥Programatically resetting:

import { watch } from 'vue'
import { useCounter, useIdle } from '@vueuse/core'

const { inc, count } = useCounter()

const { idle, lastActive, reset } = useIdle(5 * 60 * 1000) // 5 min

watch(idle, (idleValue) => {
  if (idleValue) {
    inc()
    console.log(`Triggered ${count.value} times`)
    reset() // restarts the idle timer. Does not change lastActive value
  }
})

组件用法

¥Component Usage

<template>
  <UseIdle v-slot="{ idle }" :timeout="5 * 60 * 1000">
    Is Idle: {{ idle }}
  </UseIdle>
</template>
