"Floating Labels in 3 lines of jQuery"
Bootstrap 3.2.0 Snippet by mouse0270

Them seems to rely javascript to do the heavy lifting. This bothered me because I knew there had to be an easier way to handle this.</p> <p><strong>PS:</strong> The reason I default the <code>data-value</code> to <code>no-js</code> is because this always the label to show up incase the user has javascript disabled.</p> <p><strong>PPS:</strong> I do not know all of the standards when it comes to using jQuery and chaining, so if my code is wrong or shouldn't be written the way it is please let me know.</p> </div> </div> </div> <!-- SCRIPT NOT NEEDED ONLY USED TO MAKE TEXTAREA AUTO RESIZE --> <script src="//cdnjs.cloudflare.com/ajax/libs/autosize.js/1.18.17/jquery.autosize.min.js"></script> <script>$('textarea').autosize({ append: false });</script>

$('form').find('[data-toggle="floatLabel"]').each(function (ev) {

sorry if this is a stupid question, but why do you put the classes inside brackets ( [ ] )? Haven't noticed that before and wondering if it has a particular purpose? thanks! And I love these! :D

Lacktone () - 5 years ago - Reply 0

It is a css coding habit I have. Basically each style sheet gets its own brackets. So it would be something like this

<div class="[ form-group ][ form-group-textarea ]">

The first set of brackets contains classes from bootstrap where the second set of brackets contain classes from my personally style sheet.

Honestly for small snippets of code such as bootsnipp it is hard to get why this help, but when working with a project that has 4-6 style sheets this method really helps keep things clean and organized.

I like that, and certainly see the benefit. I have a project with multiple styles and it does get cumbersome at times. Wanted to make sure I wasn't missing out on some reason code wise :D I only pretend to be a programmer, and fairly new to javascript / jquery.

Thanks for the quick reply!

Always a good idea to cache the selectors when using an element multiple times, and you might as well use jQuery's data function:

It is PPS not PSS, because PS is post-script so it would be post-post-script.
