1.父组件

在router-view 中增加isRouterAlive

<router-viewv-if="isRouterAlive"ref="routerView"/>

provide () {return {reload: this.reload}},data() {return {isRouterAlive:true,};},methods: {reload () {this.isRouterAlive = falsethis.$nextTick(function () {this.isRouterAlive = true})}

2.子组件引入父组件方法在调用的地方this.reload() 方法就行了

name: 'subDemo',inject: ['reload'],
