Utilizing Translation in Ionic Framework for AngularJS Menus

Having integrated Angular NG Translate into my app, I ran into a roadblock when attempting to translate the side menu items. The usual method of using expressions like {{'TEXT1' | translate }} did not work for me due to the format already in use in my app.component.ts file. Despite trying to nest translations within expressions, it was unsuccessful and I may have missed a step.

The code snippet from my app.component.ts for the sidemenu is as follows:

appPages: PageInterface[] = [
  { title: 'PageA', component: TabsPage, tabComponent: PageAPage },
  { title: 'PageB', component: TabsPage, tabComponent: PageBPage },
  { title: 'PageC', component: TabsPage, tabComponent: PageCPage },
  { title: 'PageD', component: TabsPage, tabComponent: PageDPage }
];

To translate each menu name (e.g., PageA), one would typically change them to:

{{'PageA' | translate }}

It seems that adding additional expressions within existing ones disrupts the translation process. Any insights or suggestions on resolving this issue would be greatly appreciated.

Answer №1

To resolve the issue, I implemented a solution where I extracted the translation key from my json file in app.component.ts and then used a standard expression to translate it in app.html. Instead of using {{p.title}}, now the menu entry output in app.html is modified to {{p.title|translate}}. If you are using a tabs navigation, some slight code modifications are required (I personally use a sidemenu).

Here is an example of what the code looks like:

appPages: PageInterface[] = [
  { title: 'PAGE_A_TITLE', component: Page1 },
  { title: 'PAGE_B_TITLE', component: Page2 },
  { title: 'PAGE_C_TITLE', component: Page3 },
  { title: 'PAGE_D_TITLE', component: Page4 }
];

Contents of en.json:

{
    "PAGE_A_TITLE": "This is page one",
    "PAGE_B_TITLE": "Title for page two",
    "PAGE_C_TITLE": "And one more",
    "PAGE_D_TITLE": "Page 4"
}

Snippet from app.html:

<ion-content>
    <ion-list>
        <button menuClose ion-item *ngFor="let p of pages" (click)="openPage(p)">
            {{p.title|translate}}
        </button>
    </ion-list>
</ion-content>
