Chapter 8. Working with JavaScript

The whole Internet would not have been the same without JavaScript, and so is Bootstrap. The JavaScript plugins from Bootstrap account for a chunk of Bootstrap's success. By having them, Bootstrap has allowed all of us to use modals, alerts, tooltips, and other plugins out of the box.

Therefore, the main focus of this chapter is to explain the main Bootstrap JavaScript plugins by using them in our web application. In the previous chapters, we used a few plugins. The purpose of this chapter is to go deep into this subject. The key points that we will cover now are:

  • General usage of Bootstrap JavaScript plugins
  • Data attributes
  • Modals
  • Tooltips
  • Popover
  • Affix

Understanding JavaScript plugins

As I said, Bootstrap offers a lot of JavaScript plugins. They all come together when we download the framework, and all of them are ready for use when the bootstrap.js file is loaded in HTML, although each plugin can be downloaded individually as well from the Bootstrap website.

Tip

Minifying JavaScript

In the production stage, you can use the minified version of Bootstrap JavaScript. We are not using that right now for learning purposes, but it is recommended that you use the minimal version when you go live.

The library dependencies

While we were setting up our development environment, we spoke about the need to import the jQuery library. Actually, jQuery is now the only required external dependency for Bootstrap.

Check out the bower.json file in the Bootstrap repository for further information about dependencies.

Tip

Bower

Bower is a package management control system for client-side components. To use Bower, you must have both Node and npm installed. Bower was developed by the developers of Twitter.

Data attributes

HTML5 introduced the idea of adding custom attributes to document tags in order to store custom information. Therefore, you can add an attribute to a tag with the data-* prefix, retrieve the information in JavaScript, and not get started with some plugin in your browser. An overwhelming majority of web browsers do support the use of custom data attributes.

With that ideology, Bootstrap implemented all the plugins to be used with just data attributes. This goes towards the framework idea to increase the speed of development and prototyping. This is because you can make use of plugins without typing JavaScript code.

To control that methodology, Bootstrap implemented an API so that you can access all plugins through only data attributes. Sometimes, however, you may want to turn off access through the API. To do so, insert the following command at the beginning of your JavaScript code:

$(document).off('.data-api');

To disable the API for some specific plugins, prepend the plugin namespace. For instance, to disable the alerts API, type this:

$(document).off('.alert.data-api');

Bootstrap JavaScript events

There is a set of events that Bootstrap produces for each plugin. They are triggered usually before and after the event starts. To exemplify this, let's say that we have a Bootstrap modal (you will learn about using modals in this chapter; don't worry) and we will call it to open by JavaScript:

$('#some-modal').modal();

When this happens, Bootstrap triggers the events called show.bs.modal and shown.bs.modal. The first one is called before the open modal call and the other is called after the action. Let's say we want to customize our modal before it is shown. To do this, we must use the first event:

$('#some-modal').on('shown.bs.modal', function(e) {
  // do some customization before shown
});

The events can be used for all plugins. Just change the namespace (in this case, .modal is the namespace) to achieve the result.
