流程表单旧版数据管理如何用批量删除？

你可以参考下图了解操作步骤及实现效果。

1. 先在网页端打开该应用表单，因为涉及到需要复制代码；

2. 将以下代码复制到控制台上；

完整代码如下：

function findReact(dom, traverseUp = 0) {
  const key = Object.keys(dom).find((_key) => (
    _key.startsWith('__reactInternalInstance$') // react <17
  ));
  const domFiber = dom[key];
  if (domFiber == null) return null;

  // react 16+
  const GetCompFiber = (fiber) => {
    // return fiber._debugOwner; // this also works, but is __DEV__ only
    let parentFiber = fiber.return;
    while (typeof parentFiber.type === 'string') {
      parentFiber = parentFiber.return;
    }
    return parentFiber;
  };
  let compFiber = GetCompFiber(domFiber);
  for (let i = 0; i < traverseUp; i += 1) {
    compFiber = GetCompFiber(compFiber);
  }
  return compFiber.stateNode;
}

const instanceListDom = document.querySelector('.instancelist');
const instanceList = findReact(instanceListDom);

const doDelete = (formInstId) => {
  const { namespace, appType } = window.pageConfig;
  const deleteInstApi = window.nattyCreateFetch({
    url: `/${namespace}/web/${appType}/query/formdata/deleteFormDataWithProc.json`,
    method: 'POST',
    data: {
      _csrf_token: document.getElementsByName('_csrf_token')[0].value,
    },
  });
  return deleteInstApi({
    formInstId,
  });
};

let curIndex = 0;
let dataLength = 0;
let errorList = [];
let batchDeleteData = [];
const deleteInst = () => {
  if (curIndex < dataLength) {
    const deleteInstId = batchDeleteData[curIndex];
    doDelete(deleteInstId).then(() => {
      console.log(`已删除: ${deleteInstId}`);
      curIndex += 1;
      deleteInst();
    }).catch((err) => {
      console.log(`删除失败: ${deleteInstId}`, err && (err.errorMsg || err.message));
      errorList.push(deleteInstId);
      curIndex += 1;
      deleteInst();
    });
  } else {
    console.log(`%c批量删除已完成, 共成功${dataLength - errorList.length} / ${dataLength}`, ' color: red;');
    if (errorList.length) {
      console.log('失败的示例数据：', errorList);
    }
    console.log('列表数据已刷新, 重新选择数据后继续批量删除，请执行 %crunBatchDelete()', ' color: #0089ff;');
    instanceList.handleRefresh('search');
  }
};

const runBatchDelete = () => {
  batchDeleteData = instanceList && instanceList.batchDeleteData || [];
  curIndex = 0;
  dataLength = batchDeleteData.length;
  errorList = [];
  deleteInst();
};
runBatchDelete();

打开控制台，复制代码

按下Enter

3. 将代码全部复制到控制台之后，在键盘上按下 Enter，会出现几行内容，在内容下再次复制 runBatchDelete() ；

回车键之后再次复制代码

4. 选中左侧的所有数据，鼠标移到控制台上，按下回车键即可删除全部数据；
