jquery select2 plugin how to match only beginning of word

问题

I am using select2 in my website and i want the autocomplete to match only the beginning of the word. For example, if I type "CA" I want CAmeroun to appear and not "vatiCAn".

I figured out how to resolve this by searching in the documentation (here https://github.com/select2/select2/issues/428).

In select2 library, replace in select2.js :

matcher: function(term, text) {
        return stripDiacritics(''+text).toUpperCase().indexOf(stripDiacritics(''+term).toUpperCase()) >= 0;
    },

by :

matcher: function(term, text) {
       if (text.toUpperCase().indexOf(term.toUpperCase()) == 0) {
        return true;
      }
    },

And tadaaa. It works. I hope someone who is better in JS (99% of JS developers) could give a better answer or create a good patch.

Don't forget to minify your JS ;) !
