前置条件：

vue版本 v3.3.11
ant-design-vue版本 v4.1.1

创建动态组件配置文件config.js

import { Input, Textarea, InputNumber, Select, RadioGroup, CheckboxGroup, DatePicker } from 'ant-design-vue';

// 表单域组件类型
export const componentsMap = {
    Text: Input,
    Textarea,
    Number: InputNumber,
    Select,
    Radio: RadioGroup,
    Checkbox: CheckboxGroup,
    DatePicker,
}

创建dynamic-form.vue组件

<template>
  <div>
    <a-form ref="formRef" :model="formModel">
      <a-form-item
        :name="item.field"
        :label="item.label"
        v-for="item in formSchema"
        :key="item.field"
        v-bind="item.formItemProps"
      >
        <component
          :is="componentsMap[item.component]"
          v-bind="item.componentProps"
          v-model:value="formModel[item.field]"
        />
      </a-form-item>
    </a-form>
  </div>
</template>

<script setup>
import { ref, watch, onMounted } from "vue";
import { componentsMap } from "./config.js";

const props = defineProps({
  // 表单项配置
  schema: {
    type: Array,
    default: () => [],
  },
  // 表单model配置，一般用于默认值、回显数据
  model: {
    type: Object,
    default: () => ({}),
  },
});

const formRef = ref(null);

const formSchema = ref([]);
const formModel = ref({});

// 表单初始化
const initForm = () => {
  formSchema.value = props.schema.map((x) => {
    return {
      ...x,
    };
  });

  // model初始数据
  formModel.value = props.schema.reduce((pre, cur) => {
    if (!pre[cur.field]) {
      // 表单初始数据(默认值)
      pre[cur.field] = cur.value;
      return pre;
    }
  }, {});
};

onMounted(() => {
  initForm();
  // 构建表单项后才回显model值,model会覆盖schema配置的value值
  watch(
    () => props.model,
    (newVal) => {
      formModel.value = { ...formModel.value, ...newVal };
    },
    {
      immediate: true,
      deep: true,
    }
  );
});

// 表单验证
const validateFields = () => {
  return new Promise((resolve, reject) => {
    formRef.value
      .validateFields()
      .then((formData) => {
        resolve(formData);
      })
      .catch((err) => reject(err));
  });
};

// 表单重置
const resetFields = (isInit = true) => {
  // 是否清空默认值
  if (isInit) {
    formModel.value = {};
  }
  formRef.value.resetFields();
};

// 暴露方法
defineExpose({
  validateFields,
  resetFields,
});
</script>

使用dynamic-form.vue组件

<template>
  <div style="padding: 200px">
    <DynamicForm ref="formRef" :schema="schema" :model="model" />
    <div style="display: flex; justify-content: center">
      <a-button @click="handleReset(true)">重置(全部清空)</a-button>
      <a-button style="margin-left: 50px" @click="handleReset(false)"
        >重置</a-button
      >
      <a-button type="primary" style="margin-left: 50px" @click="handleSubmit"
        >提交</a-button
      >
    </div>
  </div>
</template>

<script setup>
import DynamicForm from "@/components/form/dynamic-form.vue";
import { ref } from "vue";
import dayjs from "dayjs";
const formRef = ref(null);

const schema = ref([

    formItemProps: {
      rules: [

    },
  },
  {
    label: "兴趣",
    field: "hobby",
    component: "Checkbox",
    componentProps: {
      options: [
        { value: 1, label: "足球" },
        { value: 2, label: "篮球" },
        { value: 3, label: "排球" },
      ],
    },
  },
  {
    label: "国家",
    field: "country",
    component: "Select",
    componentProps: {
      allowClear: true,
      options: [
        { value: 1, label: "中国" },
        { value: 2, label: "美国" },
        { value: 3, label: "俄罗斯" },
      ],
    },
  },
  {
    label: "简介",
    field: "desc",
    component: "Textarea",
    componentProps: {
      allowClear: true,
      autoSize: {
        minRows: 4,
        maxRows: 4,
      },
      maxlength: 200,
      showCount: true,
    },
  },
]);
const model = ref({ name: "百里守约" });
// 提交
const handleSubmit = async () => {
  const formData = await formRef.value.validateFields();
  if (formData.birthday) {
    formData.birthday = dayjs(formData.birthday).format("YYYY-MM-DD");
  }
  console.log("提交信息:", formData);
};

// 重置
const handleReset = (isInit) => {
  formRef.value.resetFields(isInit);
};
</script>
