Exploring the world of ng2-translate for translating texts

For the translation of headings and texts in my Angular2 web application, I utilized ng2-translate. However, I am facing a dilemma when it comes to translating texts that are passed from a .ts file.
For example, I can easily translate texts in an HTML file as shown below.

<ion-row id="login-row">
      <ion-col>
        <ion-list>
          <ion-item>
            <ion-label stacked>{{ 'USERNAME' | translate }}</ion-label>
            <ion-input type="text" [(ngModel)]="username"></ion-input>
          </ion-item>
          <ion-item>
            <ion-label stacked>{{ 'PASSWORD' | translate }}</ion-label>
            <ion-input type="password" [(ngModel)]="password"></ion-input>
          </ion-item>
        </ion-list>
      </ion-col>
    </ion-row>

However, if I have text in a .ts file like the following, then how can I go about translating those texts?

    doCheckbox() {
    let alert = this.alertCtrl.create();
    alert.setTitle('Please Select a Location');

     alert.addInput({
       type: 'radio',
       label: 'Option 1',
       value: 'opt1',
       checked: true
     });

     alert.addInput({
       type: 'radio',
       label: 'Option 2',
       value: 'opt2'
     });

    alert.addButton({
      text: 'OK',
      handler: data => {
        this.testRadioOpen = false;
        this.testRadioResult = data;
      }
    });
    alert.present();
  }

In the above example, I aim to translate texts such as

'Please Select a Location', 'Option 1','Option 2', 'OK'...

If anyone has a solution to solve this issue, please assist me. Thank you.

Answer №1

After much searching, I finally discovered the solution. The ng2-translate API provided the answer at (https://github.com/ocombe/ng2-translate#api)

For example:

this.translate.get("SPANISH")
        .subscribe((data: string) => {
          this.selectedLanguage = data;
        });

The get() method will return the translated string or object (if a string array is passed)

To use ng2-translate, you must import it as

import {TranslateService} from 'ng2-translate;'
and define it in your constructor.
