el-form只对rules中个别字段进行校验

正常属性校验方式

const moveToErr = () => {
  const errorDom = document.getElementsByClassName('el-form-item__error');
  console.log(errorDom)
  if (errorDom.length) {
    errorDom[0].scrollIntoView({
      block: 'center',
      behavior: 'smooth'
    })
  }
};

const saveItem = async (formEl?: FormInstance | undefined) => {
  const newFormEl = formEl?.[0] ? formEl[0] : formEl;
  if (newFormEl) {
    const valid = await newFormEl.validate((valid, fields) => !!valid);
    if (!valid) {
      moveToErr();
      return false;
    }
  }
}

针对个别属性进行校验(validateField)

const submitVideoUpload = async (formEl?: FormInstance | undefined) => {
  const newFormEl = formEl?.[0] ? formEl[0] : formEl;
  console.log(newFormEl, 'newFormEl')
  if (newFormEl) {
    const valid = await newFormEl.validateField('video', (valid, fields) => !!valid);
    if (!valid) {
      moveToErr();
      return false;
    }
  }
}
