The editor also shares with you the corresponding problems of data in Vue3. Let's take an example like this Vue.createApp({ template: `<div>{{ nameObj.name }}</div>`, setup() { const { reactive } = Vue const nameObj = reactive({name:'lilei',age:18}) setTimeout(() => { nameObj.name = 'hanmeimei' },2000) return { nameObj } } }).mount('#root') At this point, we may think of the content about destructuring assignment in Vue.createApp({ template: `<div>{{ name }}</div>`, setup() { const { reactive, toRefs } = Vue const nameObj = reactive({name:'lilei',age:18}) let { name } = nameObj setTimeout(() => { name.value = 'hanmeimei' },2000) return { name } } }).mount('#root') In actual operation, we found that the content on the page did not become Vue.createApp({ template: `<div>{{ name }}</div>`, setup() { const { reactive, toRefs } = Vue const nameObj = reactive({name:'lilei',age:18}) let { name } = toRefs(nameObj) setTimeout(() => { name.value = 'hanmeimei' },2000) return { name } } }).mount('#root') Similarly, Vue.createApp({ template: `<div>{{ age }}</div>`, setup() { const { reactive, toRef } = Vue const nameObj = reactive({name:'lilei'}) let age = toRef(nameObj,'age') setTimeout(() => { age.value = 'hanmeimei' },2000) return { age } } }).mount('#root') This is the end of this article about the details of Refs and Ref in Vue3.
