vue组件刷新

1.app.vue

<template>
  <div id="app">
    <!--<img src="./assets/logo.png">-->
    <router-view v-if="isRouteAlive"/>
  </div>
</template>

<script>
export default {
  name: 'App',
  provide () {
    return {
      reload: this.relord
    }
  },
  data () {
    return {
      isRouteAlive: true
    }
  },
  methods: {
    reload () {
      this.isRouteAlive = false
      this.$nextTick (() => {
        this.isRouteAlive = true
      })
    }
  }
}
</script>

2.需要刷新的组件

<template>
  <div class="hello">
    <el-button @click="refresh">刷新</el-button>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
  inject: ['reload'],
  created () {
    console.log('created-测试')
  },
  mounted () {
    console.log("mounted-测试")
  },
  methods: {
    refresh () {
      this.reload()
    }
  }
}
</script>
