• This change requires a documentation update

添加 valueFormat方法 和 isHandleDefaultValue 属性(用来判断valueFormat是否对默认值生效)

例如下面例子，在upload组件的 field1中绑定的值只能是 string[] 格式的值。假如数据格式要求是要string格式的值，那么需要做额外的处理。现在可以通过 valueFormat这个方法，直接把field1 变成string格式的

<template>
  <Alert message="新功能测试" />
  <BasicForm @register="registerValiate" class="my-5" />
</template>

<script setup lang="ts">
  import { Alert } from 'ant-design-vue';
  import { BasicForm, FormSchema, useForm } from '@/components/Form';
  import { useMessage } from '@/hooks/web/useMessage';
  import { uploadApi } from '@/api/sys/upload';

  const { createMessage } = useMessage();

  const schemasValiate: FormSchema[] = [
    {
      field: 'field1',
      component: 'ImageUpload',
      label: '字段1',
      defaultValue:["https://avatars.githubusercontent.com/u/1"],
      componentProps: {
        api: uploadApi,
        maxNumber:1
      },
      valueFormat:({value})=>{
        return value[0]
      },
    }
  ];
  const [registerValiate, { getFieldsValue: getFieldsValueValiate}] = useForm({
    labelWidth: 160,
    schemas: schemasValiate,
    actionColOptions: {
      span: 18,
    },
    submitFunc: () => {
      return new Promise((resolve) => {
        resolve();
        console.log(getFieldsValueValiate());
        createMessage.success(`请到控制台查看结果`);
      });
    },
  });
</script>
