Overview of this book

<p>Backbone.js is an open source, JavaScript library that helps you to build sophisticated and structured web apps. It's important to have well-organized frontend code for easy maintenance and extendability. With the Backbone framework, you'll be able to build applications that are a breeze to manage.<br /><br />In this book, you will discover how to build seven complete web applications from scratch. You'll learn how to use all the components of the Backbone framework individually, and how to use them together to create fully featured applications. In addition, you'll also learn how Backbone thinks so you can leverage it to write the most efficient frontend JavaScript code.<br /><br />Through this book, you will learn to write good server-side JavaScript to support your frontend applications. This easy-to-follow guide is packed with projects, code, and solid explanations that will give you the confidence to write your own web applications from scratch.</p>

Deleting a record


As the button is already in place, we just have to wire it up. In EventView, let's add the event listener as follows:

events: {
  "click .delete" : "destroy"
},

You know what's next. We need to create the destroy method in the EventView class. It can be done as follows:

destroy: function (evt) {
  evt.preventDefault();
  this.model.destroy();
  this.remove();
},
remove: function () {
  this.$el.fadeOut(Backbone.View.prototype.remove.bind(this));
  return false;
}

The destroy method will call the model's destroy method and then call this view's remove method. Normally, that would be all, but we want to add a touch more. We want to fade the table row out and then remove the DOM elements. So, we're overwriting the default Backbone View remove method. We'll use jQuery to fade the element out. The fadeOut method that jQuery has takes a callback, a function that will be called after the fadeout is complete. We can get the usual Backbone View remove method from the Backbone.View.prototype...
