antd 3.x动态表单 对象数组

补充
编辑的时候要把 id 赋值为list最后一项的id
否则在编辑的时候新添加一条id会重复

官网例子是单个的

关键点改造

remove = index => {
  const { form } = this.props;
  // 可以使用数据绑定来获取
  const keys = form.getFieldValue('keys');
  const deviceInventory = form.getFieldValue('deviceInventory');

  // 至少有一条
  if (keys.length === 1) {
    return;
  }

  form.setFieldsValue({
    keys: keys.filter((item, key) => key !== index),
    deviceInventory: deviceInventory.filter((item, key) => key !== index),
  });
};

add = () => {
  const { form } = this.props;
  // 可以使用数据绑定来获取
  const keys = form.getFieldValue('keys');
  console.log(id, '添加一条', keys);
  id++;
  const nextKeys = keys.concat({
    id,
  });
  console.log(id, '完成', nextKeys);
  form.setFieldsValue(
    {
      keys: nextKeys,
    },
    () => {
      console.log('获取数组值', form.getFieldValue('deviceInventory'));
    }
  );
};

提交
deviceInventory list没有id
keys 只有id
合并后编辑就不会有问题了

let deviceInventory = [];

deviceInventory = fieldsValue.keys.reduce((total, item, index, arr) => {
  total.push({
    ...item,
    ...fieldsValue.deviceInventory[index],
  });
  return total;
}, []);

表单

getFieldDecorator('keys', {
  initialValue: this.state.form.deviceInventory,
});
const keys = getFieldValue('keys');
const formItems = keys.map((k, index) => (
  <>
    
      
        
          {getFieldDecorator(`deviceInventory[${index}].deviceName`, {
            initialValue: k.deviceName,
            rules: [
              {
                required: true,
                message: '请输入名称',
              },
              {
                max: 15,
                message: '输入超过限制',
              },
            ],
          })()}
        
      
      
        
          {getFieldDecorator(`deviceInventory[${index}].deviceNum`, {
            initialValue: k.deviceNum,
            rules: [
              {
                required: true,
                message: '请输入数量',
              },
              {
                max: 9,
                message: '输入超过限制',
              },
            ],
          })(
            
          )}
        
      

      {keys.length > 1 ? (
        
          
             this.remove(index)}
            />
          
        
      ) : null}
    
  
));
