Is it possible to load a Handlebars template via Ajax?

Question

I would like to load additional templates on the fly. Is it possible?

Answer 1

You can register new templates in Ember.TEMPLATES. They will then be available to views.

An excerpt from my code (jQuery Ajax handler):

success: function(data) {
  $(data).filter('script[type="text/x-handlebars"]').each(function() {
    templateName = $(this).attr('data-template-name');
    Ember.TEMPLATES[templateName] = Ember.Handlebars.compile($(this).html());
  });
}

That's it.

I was just looking for the same thing and am about to have a play with the snippet below

<script>
/*
 * Loads a handlebars.js template at a given URL. Takes an optional name, in which     case,
 * the template is added and is reference-able via templateName.
 */
function loadTemplate(url, name, callback) {
  var contents = $.get(url, function(templateText) {
    var compiledTemplate = Ember.Handlebars.compile(templateText);
    if (name) {
      Ember.TEMPLATES[name] = compiledTemplate
    } else {
      Ember.View.create({ template: compiledTemplate }).append();
    }
    if (callback) {
      callback();
    }
  });
}
</script>

I am using requirejs along with text plugin to load handlebar templates dynamically.

r.js optimizer will compile the handlerbar template to text file, which can be loaded easily using requirejs or even ajax
