问题描述TS入门课9.3节使用ant-D的modal组件显示Login组件，Login中的a-input组件输入数据失焦后，值被清空@边城问题出现的环境背景及自己尝试过哪些方法相关插件版本：{ "name": "todo-static", "version": "0.1.0", "private": true, "scripts": { "serve": "vue-cli-service serve", "build": "vue-cli-service build", "test:unit": "vue-cli-service test:unit", "lint": "vue-cli-service lint" }, "dependencies": { "ant-design-vue": "^1.7.8", "axios": "^0.24.0", "core-js": "^3.18.3", "lodash": "^4.17.21", "vue": "^2.6.14", "vue-class-component": "^7.2.6", "vue-property-decorator": "^9.1.2", "vue-router": "^3.5.2" }, "devDependencies": { "@types/jest": "^24.9.1", "@types/lodash": "^4.14.178", "@typescript-eslint/eslint-plugin": "^4.33.0", "@typescript-eslint/parser": "^4.33.0", "@vue/cli-plugin-babel": "^4.5.14", "@vue/cli-plugin-eslint": "^4.5.14", "@vue/cli-plugin-router": "^4.5.14", "@vue/cli-plugin-typescript": "^4.5.14", "@vue/cli-plugin-unit-jest": "^4.5.14", "@vue/cli-service": "^4.5.14", "@vue/eslint-config-typescript": "^7.0.0", "@vue/test-utils": "^1.2.2", "eslint": "^6.8.0", "eslint-plugin-vue": "^6.2.2", "less": "^3.13.1", "less-loader": "^5.0.0", "typescript": "^4.1.6", "vue-template-compiler": "^2.6.14" }}相关依赖："ant-design-vue","vue-property-decorator"根据相关链接提示，这个问题的原因貌似是因为使用"vue-property-decorator"的@PropSync时需要在父级组件中使用.sync,我想请教如何在createElement中使用.sync修饰符。相关代码粘贴代码文本（请勿用截图）Login.tsimport {Component, PropSync, Vue} from "vue-property-decorator";@Componentexport default class Login extends Vue{ @PropSync("username", { default: "" }) localUsername!: string; @PropSync("password", { default: "" }) localPassword!: string;}Login.vue<template> <a-form> <a-form-item> <a-input v-model="localUsername" autocomplete="username" size="large" placeholder="用户名"> <a-icon slot="prefix" type="user"></a-icon> </a-input> </a-form-item> <a-form-item> <a-input-password v-model="localPassword" autocomplete="current-password" size="large" placeholder="密码"> <a-icon slot="prefix" type="key"></a-icon> </a-input-password> </a-form-item> </a-form></template><script lang="ts" src="./Login.ts"></script>handlerError.tsisLogging = true; const user = { username: "", password: "" }; Modal.info({ title: "请登录", icon: "user", content: (createElement: any) => createElement( Login, { on: { "update:username": (value: string) => { console.log(value); user.username = value; }, "update:password": (value: string) => { console.log(value); user.password = value; } } } ), async onOk() { const { username, password } = user; const result = await new RemoteAuthApi().login(username, password); if(result?.token){ // 登录成功 isLogging = false; }else{ return Promise.reject(); } } });你期待的结果是什么？实际看到的错误信息又是什么？
