Si vous voulez qu'un changement de langue dynamique avec ngx-translate fonctionne pour vous, voici la solution, elle fonctionne pour moi.
mat-paginator-i18n.service.ts
import { MatPaginatorIntl } from '@angular/material';
import { TranslateService } from '@ngx-translate/core';
import { Injectable } from '@angular/core';
const ITEMS_PER_PAGE = 'Items per page:';
const NEXT_PAGE = 'Next page';
const PREV_PAGE = 'Previous page';
const FIRST_PAGE = 'First page';
const LAST_PAGE = 'Last page';
@Injectable()
export class MatPaginatorI18nService extends MatPaginatorIntl {
public constructor(private translate: TranslateService) {
super();
this.translate.onLangChange.subscribe((e: Event) => {
this.getAndInitTranslations();
});
this.getAndInitTranslations();
}
public getRangeLabel = (page: number, pageSize: number, length: number): string => {
if (length === 0 || pageSize === 0) {
return `0 / ${length}`;
}
length = Math.max(length, 0);
const startIndex: number = page * pageSize;
const endIndex: number = startIndex < length
? Math.min(startIndex + pageSize, length)
: startIndex + pageSize;
return `${startIndex + 1} - ${endIndex} / ${length}`;
};
public getAndInitTranslations(): void {
this.translate.get([
ITEMS_PER_PAGE,
NEXT_PAGE,
PREV_PAGE,
FIRST_PAGE,
LAST_PAGE,
])
.subscribe((translation: any) => {
this.itemsPerPageLabel = translation[ITEMS_PER_PAGE];
this.nextPageLabel = translation[NEXT_PAGE];
this.previousPageLabel = translation[PREV_PAGE];
this.firstPageLabel = translation[FIRST_PAGE];
this.lastPageLabel = translation[LAST_PAGE];
this.changes.next();
});
}
}
Dans votre module AppModule
@NgModule({
// ...
providers: [
{
provide: MatPaginatorIntl,
useClass: MatPaginatorI18nService,
},
],
})
export class AppModule {
// ...
en.json, etc.
{
"Items per page:": "Items per page:",
"Next page": "Next page",
"Previous page": "Previous page",
"First page": "First page",
"Last page": "Last page",
}

Vous devriez supprimer l'initialisation des étiquettes du constructeur et cela devrait fonctionner.
