如何解决在 array_sum 中格式化数组中的数字
我在 laravel 项目中有一个视图,我必须打印一些数组列的总和。
// First of all define some "private" subjects
// Subjects are used to allow multicasting,i.e. more clients sharing the same stream
const _isLoading$ = new BehavIoUrSubject<boolean>(false);
const _state$ = new Subject<any>();
// Then define the "public" API streams,i.e. the streams the clients can subscribe to
// isLoading$ notifies when the isLoading value changes
export const isLoading$ = _isLoading$.asObservable();
// state$ notifies when the state value changes
export const state$ = _state$.asObservable();
// Now we define a function to fire the fetch and the relative changes in isLoading
export fetch() = () => {
// first we notify that isLoading is true
_isLoading$.next(true)
// then we fire the fetch operation
from(fetch(....)) // from transforms a Promise to an Observable
// pipe applies the transformations you need to the data notified by the upstream
// as well as fires side effects
.pipe(
// as soon as the fetch operation returns we notify the change in isLaoding
tap({
next: () => _isLoading$.next(false),error: () => _isLoading$.next(false) // you can do more if you want with the error
}),// finally we apply the required transformations
map(data => {
const newState = // do anything you need to create the new state with the data fetched
return newState
}),// eventually you notify the changes in the state using the private Subject
tap(_state$)
)
}
它工作正常。但是有一个问题。
数字列有一个格式化的意大利货币数字,如下所示:
1.267,76 欧元
在刀片视图中执行求和之前,如何将所有数字格式化为 1267.76?
谢谢
