How to correctly add a jQuery UI autocomplete widget using Backbone.js

Asked By: Anonymous

I am in the process of learning Backbone.js. I currently assume that if one is using Backbone.js then all client-side javascript/jQuery should be integrated with Backbone. From the various online tutorials I can see how Backbone works and understand its underlying principles.

But what about things like jQuery UI widgets? Should these also be integrated with Backbone.js? For example, I want to use the jQuery UI Autocomplete widget on a form field (See code below). How would I go about doing this with Backbone.js (or would one not bother using Backbone for such things)? It seems like Backbone ‘Model’ and ‘Collection’ wouldn’t work with the jQuery Autocomplete Widget, since that kind of stuff is tied up within the jQuery UI Widget itself.

(function($){

  $(document).ready(function() {
    $(this.el).autocomplete({
      source: function(req, res) {
        $.ajax({
          url: '/orgs.json?terms=' + encodeURIComponent(req.term),
          type: 'GET',
          success: function(data) { 
            res(data); 
          },
          error: function(jqXHR, textStatus, errorThrown) {
            alert('Something went wrong in the client side javascript.');
          },
          dataType: 'json',
          cache: false
        });
      }
    });
  });

})(jQuery);

What is the standard practice for such things? The only thing I could think of was to create a view and then add the widget in the render function. But this doesn’t really seem very Backbone-ish to me.

Attache all your plugins when you render the view:

you can do something like this:

render: function () {

  var view = this;
  // Fetch the template, render it to the View element and call done.

  application_namespace.fetchTemplate(this.template, function (tmpl) {
    var viewModel = view.model.toJSON();
    view.$el.html(tmpl(viewModel));

    view.$("#categories").autocomplete({
      minLength: 1,
      source: function (request, response) {
        $.getJSON("url" + view.storeId, {
            term: request.term,
          }, function (data) {
            response($.map(data, function (item) {
              return {
                value: item.title,
                obj: item
              };
          }));
        });
      },

      select: function (event, ui) {
        //your select code here
        var x = ui.item.obj;
        var categories = view.model.get("x");

        // bla bla
      }
      error: function (event, ui) {
        //your error code here
      }
    }
  });
}

Hope that helps
