vNode 只是用来描述DOM,自身不维护状态,messageBox只是利用vNode渲染DOM,要想实现messageBox内容响应式,需要提供Vue实例(组件):
写一个这样的组件
- 新建组件(customRadioGroup.js):
import Vue from "vue"; const CustomInput = Vue.component("CustomRadioGroup", { props: ["value"], data() { return { internalValue: this.value, }; }, watch: { value(newVal) { this.internalValue = newVal; }, }, render(h) { return h( "el-input", { props: { value: this.internalValue }, on: { input: (value) => { this.internalValue = value; this.$emit("input", value); }, }, }, ); }, }); export default CustomInput;
然后这样引用
import CustomInput from "./CustomInput.js" this.$msgbox({ confirmButtonText: '确认', cancelButtonText: '取消', title:`订正${item.checkingItemName}`, message: h(CustomInput, { props: { value: this.password }, on: { input: (value) => { this.password = value; }, }, }), }).then(() => { console.log(this.password); }).catch(() => { console.log('取消保存'); });
