APP是主页面
HOME LIST 是路由页面 HOME是父组件 LIST是子组件
以下是他们的加载顺序:
APP beforeCreate
APP created
APP mounted
APP before update
Home beforeCreate
Home created
LIST beforeCreate
LIST created
LIST mounted
Home mounted
APP updated
1.主页面比路由先创建、挂载
2.父组件比子组件先创建，但子组件比父组件先挂载完。
不要放在methods处
beforeCreate() {
console.log("Home beforeCreate", this);
},
created() {
console.log("Home created", this);
},
beforeMouted() {
console.log("Home beforeMouted", this);
},
mounted() {
console.log("Home mounted", this);
},
beforeUpdate() {
console.log("Home before update");
},
updated() {
console.log("Home updated");
},
beforeDestroy() {
// 及时销毁，否则可能造成内存泄露
console.log("Home beforeDestroy");
},
destroyed() {
console.log("Home Destroy");
},
