Passing query parameter to backend using at.js for twitter-style-mention triggered autocomplete

Question

I'm using at.js via:

$('#post-body').atwho(
        at:"@",
        data: "/home/mention_autocomplete",
        limit: 7
        )

I would like to pass whatever the user has typed after the '@' symbol to the backend for query and returning relevant results. Is this data accessible inside the .atwho() method?

Answer 1

you can use remote_filter callback.

$('#inputor').atwho({
  at: '@', 
  callbacks: {
    remote_filter: function(query, callback) {
      $.getJSON("/home/mention_autocomplete", {q: 'whatever'}, function(data) {
        callback(data.usernames);
      });
    }
  }
});
