Suppose this is the provided json file for the translations.
{
"TRANSLATION_ID": "{{username}} is logged in.",
"ANOTHER_ID": "PascalPrecht"
}
And this is the js code:
let expressionToTranslate = "TRANSLATION_ID"
let username = "ANOTHER_ID"
If we do the following:
{{expressionToTranslate | translate:username}}
We will get "ANOTHER_ID is logged in".
How is it possible to actually translate the variable in order to be able to have "PascalPrecht is logged in"?
For anyone interested in solving this problem, I solved it with the following:
inside the controller/component I used
$translate(username).then((paragraph)=>{
username = paragraph
});
Now username became 'PascalPrecht'. And then rendered
{{expressionToTranslate | translate:{username: username}}}
in the view.
