Vue 3.0 中如何重置 reactive 定义的数据，恢复为初始值？ - 知乎
1、直接挨个重置数据（不适用对象中有多个属性，比较繁琐）
import { reactive } from 'vue' const state = reactive({ count: 0, name: 'John' }) // 重置数据： state.count = 0 state.name = 'John'
2、使用Object.assign()
import { reactive, ref } from "vue"; //保存初始化数据 const initInputData = { datasourceName: "", driverClassName: "", url: "", userName: "", password: "", startYear: "", endYear: "", status: true, action: "submit", id: "", ip:'', port:'' } const inputData = reactive({...initInputData}); //重置函数 const resetInputData = () => { Object.assign(inputData,initInputData) }
