X-IMG: HTML5 Web Component for Image Lazy Loading and More


AcidJs.XImg is a HTML5 Web Component, wrapped as a custom extended image tag supporting out-of-the-box lazy loading, native getters, setters and JavaScript methods. And what is is most important, using it is as simple as:




HTML Attributes of the Tag

Any native HTML attribute (id, class, data-*, style, etc.) is supported, plus the img/acidjs-ximg-specific:

  • src – URI of the image that will be loaded when scrolled into view.
  • width – width of the image in pixels.
  • height – Height of the image in pixels.
  • title – Optional title of the image.
  • placeholder – Optional URI to the placeholder image. If not set, one of the system will be used (Check the PLACEHOLDERS object in the AcidJs.XImg/classes/XImg.file). You can create your own base-64-encode placeholder with this online tool and add them to the PLACEHOLDERS.

All attributes are also getters/setters.

JavaScript Events of the Tag

Any native JavaScript event (click, mouseover, etc.)

JavaScript Methods of the Tag

Any native JavaScript method (document.getElementById, document.querySelector, element.setAttribute, element.removeAttribute etc.
