About

Focus is a minimal popup, modal, overlay, notification, drawer, accordion and dialogue window plugin built by Elkfox.

Features

  • Under 4 KB
  • Easy to use data API
  • No dependencies

Getting Started

Grab focus.js or focus.min.js from the repository.

Include the script in your html file.

<script src="<path_to_javascript_files>/focus.min.js"></script>

Or if you’re using Shopify include the following in your theme.liquid

{{ 'focus.min.js' | asset_url | script_tag }}

Optionally include the styles located in the css directory of the repository.

Include add a Focus element with this basic structure.

  <button data-trigger="popup" data-target="#examplePopup">Click Me</button>      <div class="popup overlay" id="examplePopup">       <div class="popup-inner">         <div class="popup-content left">            <h2>Hello world!</h2>            <a class="popup-close" data-close aria-label="Close popup">Close popup</a>         </div>       </div>     </div>

Now whenever someone clicks the β€œClick Me” button it will open the #examplePopup Focus element which contains a button to close the modal. Pretty easy!

Note that the data-close doesn’t have a data-target attribute. When this is the case data close will close the Focus element that it is contained within.

Here we also use .popup-inner to close the Focus element when a user clicks outside of the popup.

The user can also use the escape key to close Focus elements.

Here we are using the simple data api to get started which consists of the following:

  • data-trigger="popup"
  • data-target="#examplePopup"
  • data-close

JavaScript

In some cases you may wish to fire your Focus element from within your JavaScript.

Say for example when a user scrolled a specific part of the page.

  <div class="popup overlay" id="scrollPopup">     <div class="popup-inner">       <div class="popup-content left">         <h2>πŸ‘ Now you're really getting focused!</h2>          <a class="popup-close" data-close>Close popup</a>       </div>     </div>   </div>    <h2 id="scrollTrigger">Scroll to here I dare you</h2>   <script>     // In this scenario we need to initialise our Focus element with JS     var scrollPopup = new Focus('#scrollPopup');      // Now scrollPopup has access to .hide .show and .toggle methods     // The following js is use to detect how far we have scrolled.      $(document).on('scroll load resize', function(){       var docTop = ($(document).scrollTop() + $(window).height());       var scrollTrigger = $('#scrollTrigger').offset().top;       if( docTop > scrollTrigger && docTop < (scrollTrigger+100) ) {         // Now we have scrolled far enough lets open the popup πŸŽ‰         scrollPopup.show();       }     })   </script>
