方案设计思路
组合式函数封装使用 Vue3 的 setup 语法和 Composition API类型泛型支持通过 TypeScript 泛型实现表单数据的强类型约束防抖功能集成内置可配置的防抖逻辑支持异步操作多控件支持统一处理 input/textarea/select/checkbox 等常见表单元素验证机制扩展点预留自定义验证逻辑的接入接口
完整实现代码
import { ref, watch, computed, Ref } from vue;
import type { MaybeRefOrGetter, ComputedRef } from vue;// 防抖函数实现兼容异步
function debounceT extends (...args: any[]) any(func: T,wait: number,immediate?: boolean
): (...args: ParametersT) void {let timeout: ReturnTypetypeof setTimeout | null null;return (...args: ParametersT) {const callNow immediate !timeout;const later () {timeout null;if (!immediate) func.apply(this, args);};clearTimeout(timeout!);timeout setTimeout(later, wait);if (callNow) func.apply(this, args);};
}// 表单字段配置接口
interface FormFieldConfigT any {value?: T;debounce?: number;validator?: (value: T) string | boolean;transform?: (value: T) any;
}// 表单状态管理类
class FormStateT extends Recordstring, any {private _rawValues: T;private fields: Recordkeyof T, FormFieldConfig;private _errors: RefRecordstring, string ref({});private _isValid: ComputedRefboolean computed(() Object.values(this._errors.value).every(msg !msg));constructor(initialValues: T, fieldConfigs: Recordkeyof T, FormFieldConfig {}) {this._rawValues initialValues;this.fields fieldConfigs;this.initFields();}private initFields() {Object.keys(this._rawValues).forEach(key {if (this.fields[key as keyof T]?.debounce) {const debounceTime this.fields[key as keyof T]!.debounce!;const originalSetter (val: any) {this._rawValues[key as keyof T] val;};this._rawValues[key as keyof T] new Proxy(this._rawValues[key as keyof T], {set: debounce((_, prop, newValue) {originalSetter(newValue);}, debounceTime)});}});}public get values(): T {return this._rawValues;}public get errors(): Recordstring, string {return this._errors.value;}public get isValid(): boolean {return this._isValid.value;}public validateField(field: keyof T): boolean {const config this.fields[field];const value this._rawValues[field];if (config?.validator) {const result config.validator(value);this._errors.value[field as string] typeof result string ? result : result ? : Invalid value;}return !this._errors.value[field as string];}public validateAll(): boolean {let isValid true;Object.keys(this._rawValues).forEach(key {if (!this.validateField(key as keyof T)) isValid false;});return isValid;}public reset(): void {this._rawValues Object.keys(this._rawValues).reduce((acc, key) ({ ...acc, [key]: this.fields[key as keyof T]?.value || }),{} as T);this._errors.value {};}
}// 组合式函数
export function useFormT extends Recordstring, any(initialValues: T,fieldConfigs?: Recordkeyof T, FormFieldConfig
) {const formState new FormState(initialValues, fieldConfigs);// 创建响应式表单值const formValues computed({get: () formState.values,set: (newValues) {Object.assign(formState.values, newValues);}});// 字段绑定函数function useFieldK extends keyof T(field: K) {const value computed({get: () formValues.value[field],set: (newValue) {formValues.value[field] newValue;}});const error computed(() formState.errors[field as string]);return {value,error,validate: () formState.validateField(field)};}// 表单提交处理async function handleSubmitR any(submitFn: (values: T) PromiseR,options?: { validate?: boolean }): PromiseR | null {if (options?.validate !formState.validateAll()) return null;try {const result await submitFn(formValues.value);formState.reset();return result;} catch (e) {console.error(Form submission error:, e);return null;}}return {values: formValues,errors: computed(() formState.errors),isValid: computed(() formState.isValid),useField,validate: () formState.validateAll(),reset: () formState.reset(),submit: handleSubmit};
}// 类型导出
export type FormFieldConfig FormFieldConfig;
export type FormStateTypeT FormStateT;使用示例
script setup langts
import { useForm } from /composables/useForm;interface LoginForm {email: string;password: string;remember: boolean;
}const formConfig {email: {debounce: 500,validator: (value: string) /^[^\s][^\s]\.[^\s]$/.test(value) ? true : Please enter a valid email address},password: {debounce: 300,validator: (value: string) value.length 8 ? true : Password must be at least 8 characters}
};const { values, errors, isValid, useField, submit } useFormLoginForm({email: ,password: ,remember: false}, formConfig);const email useField(email);
const password useField(password);
const remember useField(remember);const handleSubmit submit(async (values) {console.log(Form submitted:, values);// 这里调用APIreturn { success: true };
});

/template方案特点分析强类型支持
使用 TypeScript 泛型确保表单数据的类型安全字段配置与验证函数类型约束组合式函数返回值类型明确防抖功能
通过 Proxy 实现动态属性拦截可配置的防抖时间字段级配置支持异步验证场景验证系统
内置验证器接口字段级错误收集表单整体有效性状态支持自定义验证逻辑扩展性设计
表单状态管理类封装核心逻辑组合式函数暴露友好API预留 transform 等数据处理钩子支持异步提交处理开发体验优化
符合 Vue 响应式设计哲学字段绑定自动推导类型错误信息自动收集展示表单提交自动重置性能优化点
防抖内存管理使用 Proxy 替代直接属性替换避免重复创建对象计算属性缓存合理使用 computed 减少不必要计算批量更新表单提交时使用 Object.assign 批量更新错误状态隔离每个字段错误状态独立存储避免全局遍历
扩展方向建议
集成第三方验证库如 Vuelidate、Yup 等添加字段掩码支持密码显示切换、敏感信息脱敏表单版本管理实现表单状态的历史记录可视化校验提示集成 UI 框架的表单验证样式国际化支持多语言错误提示
本方案通过 TypeScript 泛型和 Vue3 组合式 API 的结合实现了类型安全、功能丰富的表单绑定解决方案。防抖功能的集成既减少了不必要的验证触发又提升了表单的响应性能同时保持了代码的可维护性和扩展性。
