ant.design（简称antd）现在我们使用较为广泛，web端中后台表单使用非常广泛，此遍文章集合了表单日常用法及使用注意事项。

        下图是UI目标样式图                

         1、以下是一个组件，首先引入ant相关依赖，在引入react相关依赖,主要使用了Form的2个内置函数和Form.useWatch进行监听指定字段,然后使用 form.setFieldsValue进行字段值更新。

        2、表单验证相关规则使用在Form.Item中配置rules即可，required设置为true是为必填项,message为对应的提示信息。

        3、onFinish函数是在按钮设置了htmlType="submit"属性，在点击效验规则全部通过时触发的函数。

        4、onFinishFailed函数是在按钮设置了htmlType="submit"属性，在点击效验规则有部分未通过效验时触发的函数。

        注意：Form.List 下的字段不应该配置 initialValue，你始终应该通过 Form.List 的 initialValue 或者 Form 的 initialValues 来配置。

        Form.useWatch#

    type Form.useWatch = (namePath: NamePath, formInstance?: FormInstance): Value

4.20.0 新增，用于直接获取 form 中字段对应的值。通过该 Hooks 可以与诸如 useSWR 进行联动从而降低维护成本：

 form.setFieldsValue({
      bbsiRuleArrangeVos: bbsiRuleArrangeVos,
 });

    console.log('Success:', values, bbsiRuleArrangeVos);
    const { ruleName, signingMethod, bbsiRuleArrangeVos,templeteId } = values;
    handleArray(bbsiRuleArrangeVos);
  };

  const handleArray = (arr) => {
    if (Array.isArray(arr)) {
      arr.map((item) => {
        item.signInBeginTime = item.signInTime ? moment(item.signInTime?.[0]).format('YYYY-MM-DD HH:mm:ss') : '';
        item.signInEndTime = item.signInTime ? moment(item.signInTime?.[1]).format('YYYY-MM-DD HH:mm:ss') : '';
        delete item.btn
        delete item.signInTime
        return item;
      });
    }

    bbsiRuleArrangeVos[index].btn = index;
    setPeopleIndex(index);
