let inProcessCount: number | undefined async function getInProcessCount(routeritem: RouteRecordRaw) { if (inProcessCount !== undefined) { return inProcessCount; } const len = await store.dispatch('ESourcingModule/GetMyRequest', searchView.value).then((list) => { // eslint-disable-next-line @typescript-eslint/no-unsafe-return, @typescript-eslint/no-unsafe-call return list.filter((o: { ViewType: string }) => o.ViewType === 'InClarification' || o.ViewType === 'SupplementEventDetails').length; }); inProcessCount = len if (routeritem?.meta) { // eslint-disable-next-line @typescript-eslint/restrict-template-expressions routeritem.meta.title = `${routeritem.meta?.title}(${inProcessCount})` } return len as number } function CheckAdmin(routeritem: RouteRecordRaw) { document.title = 'RMS E-Sourcing' if (routeritem?.meta?.title === 'My Request') { debugger void getInProcessCount(routeritem) }}

在 `CheckAdmin` 方法中调用 `getInProcessCount` 方法时，可以使用 `await` 等待其执行完成，并获取返回值，以确保在更新 `routeritem.meta.title` 时使用的是最新的计数值。例如：

async function CheckAdmin(routeritem: RouteRecordRaw) {
  document.title = 'RMS E-Sourcing';
  if (routeritem?.meta?.title === 'My Request') {
    const len = await getInProcessCount(routeritem);
    routeritem.meta.title = `${routeritem.meta?.title}(${len})`;
  }
}

这样，当 `CheckAdmin` 方法调用 `getInProcessCount` 方法时，会等待其执行完成，并获取返回值 `len`，以后再更新 `routeritem.meta.title` 时使用的就是最新的计数值。

let inProcessCount: number | undefined; async function getInProcessCount() { if (inProcessCount !== undefined) { return inProcessCount; } const list = await store.dispatch('ESourcingModule/GetMyRequest', searchView.value); // eslint-disable-next-line @typescript-eslint/no-unsafe-call const len = list.filter((o: { ViewType: string }) => o.ViewType === 'InClarification' || o.ViewType === 'SupplementEventDetails').length; inProcessCount = len; if (eSourcingRoute) { // 如果 eSourcingRoute 变量不为 undefined const myRequestIndex = eSourcingRoute.findIndex(route => route.meta?.title === 'My Request'); if (myRequestIndex !== -1 && eSourcingRoute[myRequestIndex].meta !== undefined) { eSourcingRoute[myRequestIndex].meta.title = 'My Request (2)' } r } eturn inProcessCount as number; }

代码中的问题在于 `r` 这个字符，它是一个语法错误，应该删除掉。

另外，代码中对 `eSourcingRoute` 变量的访问也存在问题，应该修改为 `if (eSourcingRoute !== undefined)`，这样才能避免 TypeScript 的类型检查错误。具体修改后的代码如下：

let inProcessCount: number | undefined;

async function getInProcessCount() {
  if (inProcessCount !== undefined) {
    return inProcessCount;
  }

  const list = await store.dispatch('ESourcingModule/GetMyRequest', searchView.value);
  const len = list.filter((o: { ViewType: string }) => o.ViewType === 'InClarification' || o.ViewType === 'SupplementEventDetails').length;
  inProcessCount = len;

  if (eSourcingRoute !== undefined) {
    const myRequestIndex = eSourcingRoute.findIndex(route => route.meta?.title === 'My Request');
    if (myRequestIndex !== -1 && eSourcingRoute[myRequestIndex].meta !== undefined) {
      eSourcingRoute[myRequestIndex].meta.title = 'My Request (2)';
    }
  }

  return inProcessCount as number;
}

修改后，代码中的问题应该就解决了。

// 获取 InProcessCount 数据 async function getInProcessCount(routeritem: RouteRecordRaw) { const len = await store.dispatch('ESourcingModule/GetMyRequest', searchView.value).then((list) => { // eslint-disable-next-line @typescript-eslint/no-unsafe-return, @typescript-eslint/no-unsafe-call return list.filter((o: { ViewType: string }) => o.ViewType === 'InClarification' || o.ViewType === 'SupplementEventDetails').length }) if (routeritem?.meta) { // eslint-disable-next-line @typescript-eslint/restrict-template-expressions routeritem.meta.title = `${routeritem.meta?.title}(${len})`; } return len as number }

可以将 `getInProcessCount` 方法的结果缓存下来，以后再调用时直接使用缓存的结果，避免重复执行。例如：

let inProcessCount: number | undefined;

async function getInProcessCount(routeritem: RouteRecordRaw) {
  if (inProcessCount !== undefined) {
    return inProcessCount;
  }
  
  const len = await store.dispatch('ESourcingModule/GetMyRequest', searchView.value).then((list) => {
    return list.filter((o: { ViewType: string }) => o.ViewType === 'InClarification' || o.ViewType === 'SupplementEventDetails').length;
  });

  if (routeritem?.meta) {
    routeritem.meta.title = `${routeritem.meta?.title}(${len})`;
  }

  inProcessCount = len;
  return len;
}

这样，第一次调用 `getInProcessCount` 方法时会执行实际的操作并将结果缓存下来，以后再调用时直接返回缓存的结果，避免重复执行。注意要将 `inProcessCount` 定义在作用域范围之外，以便在多次调用时保留状态。
