1、在App.vue文件中watch:{$route(data){xx}}在路由改变或参数改变时,会触发监听事件

代码示例:

<template><div id="app"><div><router-link to='/'>首页</router-link><router-link to='/a'>a页</router-link></div><router-view></router-view></div>
</template><script>export default {name: 'App',data(){return{}},components:{},methods:{},watch:{$route(data){console.log(data);console.log('路由改变');console.log(this.$route.params.id);}}
}
</script><style scoped >*{margin:0;padding: 0;
}</style>
