vue开发常见问题总结

Unknown custom element: <router-view> - did you register the component correctly? For recursive components, make sure to provide the "name" option. (found in <Root>)

// 父组件
<router-view v-if="isReload"></router-view>
data() {
return {
isReload: true
}
},
methods: {
reload() {
this.isReload = false
this.$nextTick(() => { this.isReload = true })
}
}
// 父组件或子组件调用
this.reload();  // 父组件
this.$root.reload();   // 子组件

<router-view :key="$route.fullPath"></router-view>
