Question

I’m running a simple AJAX post to my server and the respond_to .js block is returned as a 200 success but is not executed. Am I missing something in my configuration or in my code for the execution the return js code? I’m using Ruby on Rails 3.2.9.

javascript:

    $("#test-submit").on("click",function(event){
      $.ajax({
        type: "POST",
        url: '/users',
        dataType: 'json',
        data: {
          "test" : "test-data"
        }
      });
      event.preventDefault();
    });

controller action:

  def create
    user = User.find(current_user)

    respond_to do |format|
      format.js { }
    end
  end

user create.js.erb:

alert('hai');

dataType: 'json',

You expect JSON data, not executable script. Try to change this line to

dataType: 'script',
