5 Cool jQuery Lazy Load Plugins

When it comes to web page performance, there are a few techniques more important than lazy loading. Lazy loading is a process of loading content only when it is required, instead of preloading all of the content at once. This can drastically improve the overall performance of a web page, especially when the page contains large amounts of images or data. Fortunately, jQuery makes it easy to implement lazy loading with plugins. In this article, we will discuss five of the coolest jQuery lazy load plugins currently available. 

  • BttrLazyLoading: BttrLazyLoading is a jQuery-powered plugin designed to improve the performance of websites. It enables the delay of loading images until the user scrolls down to them. Additionally, the plugin provides users with different versions of an image depending on the device they are using. For example, if the user is on a phone, the image will be less than 768px, on a tablet, it will be more than 768px, on a desktop, it will be more than 992px and on a large desktop it will be less than 1200px.
  • Jquery Lazy Load Any: It is a jQuery plugin that allows users to defer the loading of HTML images, frames, and other content in any browser. This plugin is based on the lazy loader concept, which helps to improve the loading speed of webpages by only loading the content that is visible on the page. With Lazy Load Any, users can install the plugin in any browser and enjoy faster loading speeds.
  // Sets the pixels to load earlier. Setting threshold to 200 causes image to load 200 pixels
  // before it appears on viewport. It should be greater or equal zero.
  threshold: 200,

  // Sets the callback function when the load event is firing.
  // element: The content in lazyload tag will be returned as a jQuery object.
  load: function(element) {},

  // Sets events to trigger lazyload. Default is customized event `appear`, it will trigger when
  // element appear in screen. You could set other events including each one separated by a space.
