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(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) { debugger // eslint-disable-next-line @typescript-eslint/restrict-template-expressions routeritem.meta.title = (`${routeritem.meta?.title}(${inProcessCount})`).replace(/\(2\)(?=[^(]*\))/g, ''); } return inProcessCount as number } 优化代码
可以将代码进行如下优化:
```typescript
let inProcessCount: number | undefined;
async function getInProcessCount(routeritem: RouteRecordRaw) {
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 (routeritem?.meta) {
routeritem.meta.title = `${routeritem.meta?.title}${inProcessCount !== 0 ? `(${inProcessCount})` : ''}`.replace(/\(2\)(?=[^(]*\))/g, '');
}
return inProcessCount as number;
}
```
主要优化点如下:
1. 将获取列表和计算列表长度的操作拆开,使代码更加清晰和易读。
2. 将判断 `inProcessCount` 是否为 `undefined` 的代码提前,减少不必要的计算。
3. 将拼接标题的代码进行了简化,使用了三元运算符,避免了不必要的字符串拼接。同时,将判断 `inProcessCount` 是否为 0 的代码加入了判断条件中,避免了出现 `title` 中只有一个空括号的情况。
其他的代码格式也进行了微调,使代码更加整洁和易读。
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。
