I would like to use JS in the Django admin to fill in programmatically a field that uses the built-in autocomplete option (NOT autocomplete-light).

Let's say the field is called myfavfield. I can retrieve it with JS as follows $("#id_myfavfield"). If it is already filled in with some values, I can retrieve them with $("#id_myfavfield").val();, which, for example, returns ['1', '4'], I can also clear myfavfield with $("#id_myfavfield").empty();. However, I can't fill it in, for example, by running $("#id_myfavfield").val(['2', '4', '5']); or any other way that I have tried. Does anybody know how one can achieve that?
