Understanding how JavaScript works in Bootstrap

From: Up and Running with Bootstrap 2

Video: Understanding how JavaScript works in Bootstrap

Bootstrap ships with a number of jQuery based plug-ins. jQuery is a JavaScript framework, and Bootstrap has written some effects using this framework. They include Modal Windows, Dropdowns, Tabs, tool Tips, Alert, Popovers, and Image Carousel, and so much more. If you're familiar with JavaScript and jQuery, you can modify anything in Bootstrap using the API. If you're not familiar with JavaScript or jQuery, don't worry, there are many effects that are created for you which you can put to use immediately. You'll need to carefully copy some code from the documentation pages into your work.

Understanding how JavaScript works in Bootstrap

Bootstrap ships with a number of jQuery based plug-ins. jQuery is a JavaScript framework, and Bootstrap has written some effects using this framework. They include Modal Windows, Dropdowns, Tabs, tool Tips, Alert, Popovers, and Image Carousel, and so much more. If you're familiar with JavaScript and jQuery, you can modify anything in Bootstrap using the API. If you're not familiar with JavaScript or jQuery, don't worry, there are many effects that are created for you which you can put to use immediately. You'll need to carefully copy some code from the documentation pages into your work.

I'm at getbootstrap.com, and I've clicked on the JavaScript link here at the top of the page, and on this page, you'll see 13 effects here that use jQuery and have been coded to work within Bootstrap. They're all listed over here on the left side of the page. There are also some items under the components part of the documentation that also require the use of JavaScript or jQuery in order for them to work. Be very sure that you're linked to the bootstrap.min.js file, as well as the latest version of jQuery.

The exercise files that I've given you contain links for that at the bottom of the pages just before the slash body tag. If you're creating these files on your own, make sure you link to both of these files, otherwise these JavaScript effects are not going to work. Remember that the .min files contain the same information as the regular JavaScript files, but the min files have the spaces removed to make the file sizes smaller. There's a few custom HTML5 attributes you should be familiar with that are going to be used in Bootstrap, and you'll see that in many places over the next few videos.

If you click on the link here for Navbar under Components, and we're going to scroll on down here to the section that talks about the Responsive navbar. Right here on line 6 you'll see these two items working together. The data-toggle is applied to a button or a link, basically anything that has to be clicked or rolled over to trigger an event or to make something happen. The data-target is something that takes the action from the controlling element. So, in the case of tabs that change content when they're clicked, the data-toggle is the link on the tabs, while the data-target is a div containing the text that should display when a tab is clicked.

So, I'm going to go through a number of these things in detail now with Bootstrap and JavaScript so that you can see how these data-toggles and data-targets work, and you can get familiar with some of the basic JavaScript inside of Bootstrap.
