ngx/translate - translate only part of a string

问题

I need to translate strings coming from a server using ngx/translate.

It works fine when i need to translate a string but in some case i need to translate only part of the string.

For example: 'hello Shay' or 'hello John'

And i need to translate only 'hello' and leave the name as is. I tried:

this.i18n.instant('hello {Shay}')

and in the en.json file: "hello {var}": "Hello {var}"

but with no success. Any Ideas how it can be done?

回答1:

You are looking for parametrized translations. You do not need that parameter in the translation key. Try it like this:

en.json:

"hello_name": "Hello {{name}}"

controller:

this.i18n.instant('hello_name', {name: 'Shay'});

or in template:

{{ 'hello_name' | translate: {name: 'Shay'} }}
