react+antd动态增删表单方式

// 获取当前的所有表单值
const lists = getFieldValue(formTitle);
// 删除后替换
for (let index in lists) {
  const nIndex = Number(index);

    formData.map(item => setFieldsValue({[`${formTitle}.${nIndex}.${item}`]: lists[nIndex + 1][item]}));
  }
}
// 删除数组数据
setDetail([...detail.slice(0, i), ...detail.slice(i, detail.length - 1)]);
