Jquery lazyload with ajax

Question

I use lazyload() on my ecommerce website. lazyload() works great. I use this code to do that:

$(function(){
  $(\"img.lazy\").lazyload({ 
  effect : \"fadeIn         


        

Answer 1

For my scenario when the page is loaded I will get list of template with template Id. Based on that template Id I use jQuery Lazy to load base64 encoded images using ajax and load image lazily on my page.

Hope you will get some idea of my approach

$(document).ready(function() {
  let imageArray = [0, 1, 10, 100, 1000, 1001];

  let parsedImageArray = $.map(imageArray, function(value) {
    return "

";
  });

  $("#content").html(parsedImageArray);

  console.log("Here" + parsedImageArray)
});


$(document).bind('DOMNodeInserted', function(e) {
  $('.lazy').lazy({
    effect: "fadeIn",
    event: "scrollstop",
    skip_invisible: true,
    removeAttribute: false,
    ajaxLoader: function(element, response) {
      let thumbnailId = element.attr("contentId");
      console.log("Here" + thumbnaiId);
      $.get("https://picsum.photos/id/" + thumbnailId, function(srcValue, status) {
        //for me i have to pull the base64 encode image from my server 
        let defaultImageDom = generateThumbnailImage(tempSrc);
        element.html(defaultImageDom);
        element.removeClass('lazy');
      }).fail(function(jqXHR, textStatus, errorThrown) {
        let defaultImageDom = generateThumbnailImage("");
        element.html(defaultImageDom);
        element.append("Error Getting Thumbnail Preview");
        element.removeClass('lazy');
      });
    },
  });
});

function generateThumbnailImage(srcValue) {
  let defaultImageDom = new Image();
  defaultImageDom.height = 200;
  defaultImageDom.style.borderColor = "#d5d5d5";
  defaultImageDom.style.borderWidth = "1px";
  defaultImageDom.style.borderStyle = "solid";

  if (srcValue && srcValue.length > 0) {
    defaultImageDom.src = srcValue;
  } else {
    //set your fallback image link
    defaultImageDom.src = "data:image/gif;base64,R0lGODdhAQABAPAAAMPDwwAAACwAAAAAAQABAAACAkQBADs=";
  }
  return defaultImageDom;
}

.lazy {
  width: 700px;
  height: 467px;
  display: block;
  /* optional way, set loading as background */
  background-image: 'data:image/gif;base64,R0lGODdhAQABAPAAAMPDwwAAACwAAAAAAQABAAACAkQBADs=';
  background-repeat: no-repeat;
  background-position: 50% 50%;
}
