标签:监听 strong -- mount bsp this root 恢复 vue
------------恢复内容开始------------
1.配置路由
{
path: ‘/hellow‘,
name:"hellow",
component: hellow,
meta:{title:"hellow"}
}
2,在mount里面赋值
mounted(){
this.title=this.$route.matched;
},
3,由于在页面上刷新才可以显示,所一需要watch监听
watch: {
‘$route.matched‘: function (newVal, oldVal) {
this.title=this.$route.matched;
}
},
3.0的监听watch(()=>root.$route,(to,from)=>{
state.title=to.matched;
})
