Rails：如何在jQuery（.js.erb）中调用“创建”操作？

Question

I am using Rails 4.1.1 I was wondering, how do I call the 'create' action in jQuery ( .js.erb )? Please see below my jquery codes and my user_controller.rb , I would like to call the user_controller.rb create action in the jquery if else code.

routes.rb

Rails.application.routes.draw do
  resources :user
  root 'user#index'
end

user_controller.rb

class UserController < ApplicationController

  def index
    @users = User.all
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    @user.save
    redirect_to "/"
  end

  private

  def user_params
    params.require(:user).permit(:email)
  end

end

subscribe.js.erb

$(function () {
  $("#subscribe").submit(function (event) {
    var input = $('.my-subscribe-message');
      if(!input.is(':empty')) {
        $('.my-subscribe-message').stop(true);
      }
      event.preventDefault();
      event.stopImmediatePropagation();

      var email = $("input#subscribe-email").val();

      if (email == "") {

        $(".my-subscribe-message").stop(true).html('<i class="fa fa-warning"></i> You must enter a valid e-mail address.');
        $("input#subscribe-email").focus();
      } 
      else if (!isValidEmailAddress( email )) {
        $(".my-subscribe-message").stop(true).html('<i class="fa fa-warning"></i> E-mail address is not valid.');
        $("input#subscribe-email").focus();            
      }
      else {
        $.ajax({

/* I would like to call the create action here */

          success: function () {
            $(".my-subscribe-message").html('<i class="fa fa-check"></i> We will be in touch soon!');
            $('input#subscribe-email').val('');
          }
        });
      }
   });
});

Give this a punt:

$.ajax({
  type: "POST",
  url: "/users",
  data: { user: { email: "blah@blah.com" } },
});
