Showhide.js is a small and extremely simple, dependency-free library to show and hide elements conditionally based on HTML data attributes. It is quite useful to create simple interactions on pages without much hassle, which is ideal for prototyping.

Clone showhide.js repository to a folder of your choice in your web project, e.g. /var/www/project/js:

cd /var/www/project/js && git clone https://github.com/Dovyski/showhide.git showhide

Just before the </head> or </body> tags, add the following:

<script src="js/showhide/showhide.js"></script>

Showhide.js uses HTML data attributes to control the show/hide logic. All happens when the user clicks an HTML element that has a data-sh-show or data-sh-hide data element:

<a href="javascript:void(0);" data-sh-show=".dynamic">Show</a>
<a href="javascript:void(0);" data-sh-hide=".dynamic">Hide</a>

<div class="dynamic">This div will be visible (or not)</div>

When the user clicks any of the <a> tags above, if it has an data-sh-show data attribute, Showhide.js will search for all elements in the page that match the query informed as the value for the data attribute, then make them visible. Similarly, if the user clicks an element with a data-sh-hide attribute, Showhide.js will hide all elements that match that query.

Showhide.js also has built-in support to create toggle-based controls:

<a href="javascript:void(0);" data-sh-toggle=".dynamic.red" data-sh-toggle-show=".toggle-show-red" data-sh-toggle-hide=".toggle-hide-red">
          
  <span class="toggle-show-red" style="display: none;">[on]</span>
  <span class="toggle-hide-red">[off]</span>
</a>

The query informed in data-sh-show, data-sh-hide, or any other data attributes supported by Showhide.js is based on jQuery selectors. It means you can do something like data-sh-show="#elementId" to show an element by its id.

Showhide.js was developed to quickly (and dirtly) show or hide elements on a page based on simple rules. It's biggest advantages are that is has no dependencies, e.g. jQuery, and is extremely simple to use. If you are looking for something more robust or powerful, check Vue.js or React.

Showhide.js is licensed under the terms of the MIT Open Source license and is available for free.
