How do you modify “No Results Found” language in Select2 v4.0

问题

I attempted to use the "language.noMatches" option when initiating Select2 and its throwing an undefined function? How do I go about modifying that bit of text? I would like to include a html button that would add the input from the user if it wasn't found. I tried doing this as a function as well as plain text. I also removed all html to see if that was doing it.

$('#search-select').select2({

   ...

   "language": {
       "noMatches": function(){
           return "No Results Found <a href='#' class='btn btn-danger'>Use it anyway</a>";
       }
   }
});

This was previously "formatNoMatches" in Select2 v3.5

The option noMatches doesn't appear anywhere in the source code.

The actual option is named noResults. The working version of your example is:

$('#search-select').select2({

   ...

   "language": {
       "noResults": function(){
           return "No Results Found <a href='#' class='btn btn-danger'>Use it anyway</a>";
       }
   },
    escapeMarkup: function (markup) {
        return markup;
    }
});

You also need to override escapeMarkup, so the button appears correctly, as per this issue.

Probably, you have to add the script for the language you want to use. Something like this:

<script src="select2/js/i18n/pt-BR.js" type="text/javascript"></script>

And then you can set the default language:

$(".select2").select2({
  "language": "pt-BR"
});

The option for select 2.5 seems formatNoMatches:

$('#search-select').select2({
  formatNoMatches: function () {
  return "No Results Found <a href='#' class='btn btn-danger'>Use it anyway</a>";
  }
});
