I want to detect the switch of the "current language" using ngx-translate library.
Which js event I can use to achieve that?
To better understand what I mean, please check this simple example: https://stackblitz.com/edit/github-yvbmgu
I want to detect the change of the currentLang from the "diff" component, on ngOnInit().
CodePudding user response：
You can subscribe to TranslateService's onLangChange observable to listen to language change events.
ngOnInit() {
console.log(this.translate.currentLang);
this.translate.onLangChange.subscribe((event: LangChangeEvent) => {
console.log(event.lang);
});
}
