React Antd4.x Upload实现图片上传后拖拽换顺序功能_antd的upload怎么将上传的文件列表和进度条位置改变

功能说明

做项目使用React Antd4.x Upload上传图片，实现批量上传。

后期项目迭代更新，要求拖拽图片调整图片顺序。

框架不支持，自己借助包写了一个上传且可以拖拽图片换位置的功能。

下面是思路具体步骤：

1、框架Upload实现批量上传，预览，删除。

2、Upload旁边增加拖拽换位置的按钮。

3、点击按钮弹窗，弹窗中实现拖拽。

设计原因：上传与拖拽互不影响。

功能实现

安装“array-move”

$ npm i array-move

安装“react-sortable-hoc"

$ npm install react-sortable-hoc --save

封装拖拽弹窗组件

组件的引用：

 <Button className='btn' onClick={() => handleChangeImagePosition()}>调整图片顺序</Button>
 
{visible && <CTSChangePosition visible={visible} fileListAll={fileListAll} onConfirm={(fileListDeal) => handleModalConfirm(fileListDeal)} onCancel={() => handleModalClose()} />}

  const handleChangeImagePosition = () => {
    setVisible(true);
  }
 
  const handleModalClose = () => {
    setVisible(false);
  }
 
  const handleModalConfirm = (fileListDeal) => {
    setFileListAll(fileListDeal);
    if (form) {
      form.setFieldsValue({
        [`${name[0]}`]: {
          [name[1]]: fileListDeal
        }
      })
    }
    handleModalClose();
  }
