This JavaScript code creates an image-loading animation. It progressively blurs an image while displaying the loading percentage. It helps visualize the loading progress<\/a> of an image.<\/p>\n

You can use this code on websites to enhance user experience during image loading. It provides a visual loading indicator for smoother interactions.<\/p>\n

How to Create Image Loading Animation in JavaScript<\/h2>\n

1. First of all, set up the HTML structure with a container for the image and a text element to display the loading percentage.<\/p>\n

<html lang=\"en\">\r\n  <head>\r\n    <meta charset=\"UTF-8\" \/>\r\n    <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" \/>\r\n    <link rel=\"stylesheet\" href=\"style.css\" \/>\r\n    <title>Blurry Loading<\/title>\r\n  <\/head>\r\n\r\n  <body>\r\n    <section class=\"bg\"><\/section>\r\n    <div class=\"loading-text\">0%<\/div>\r\n    <script src=\"script.js\"><\/script>\r\n  <\/body>\r\n<\/html>\r\n<\/pre>\n
2. Apply basic styling to the elements, adjusting fonts, positioning, and background blur. You can modify the CSS styles according to your needs.<\/p>\n
@import url('https:\/\/fonts.googleapis.com\/css?family=Ubuntu');\r\n\r\n* {\r\n  box-sizing: border-box;\r\n}\r\n\r\nbody {\r\n  font-family: 'Ubuntu', sans-serif;\r\n  display: flex;\r\n  align-items: center;\r\n  justify-content: center;\r\n  height: 100vh;\r\n  overflow: hidden;\r\n  margin: 0;\r\n}\r\n\r\n.bg {\r\n  background: url('https:\/\/images.unsplash.com\/photo-1576161787924-01bb08dad4a4?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=2104&q=80')\r\n    no-repeat center center\/cover;\r\n  position: absolute;\r\n  top: -30px;\r\n  left: -30px;\r\n  width: calc(100vw + 60px);\r\n  height: calc(100vh + 60px);\r\n  z-index: -1;\r\n  filter: blur(0px);\r\n}\r\n\r\n.loading-text {\r\n  font-size: 50px;\r\n  color: #fff;\r\n}<\/pre>\n
3. Finally, use JavaScript to manipulate the loading text<\/a> and apply blur effects. It sets up a function blurring()<\/code> that increases the loading percentage and adjusts the blur effect accordingly.<\/p>\n
const loadText = document.querySelector('.loading-text')\r\nconst bg = document.querySelector('.bg')\r\n\r\nlet load = 0\r\n\r\nlet int = setInterval(blurring, 30)\r\n\r\nfunction blurring() {\r\n  load++\r\n\r\n  if (load > 99) {\r\n    clearInterval(int)\r\n  }\r\n\r\n  loadText.innerText = `${load}%`\r\n  loadText.style.opacity = scale(load, 0, 100, 1, 0)\r\n  bg.style.filter = `blur(${scale(load, 0, 100, 30, 0)}px)`\r\n}\r\n\r\n\/\/ https:\/\/stackoverflow.com\/questions\/10756313\/javascript-jquery-map-a-range-of-numbers-to-another-range-of-numbers\r\nconst scale = (num, in_min, in_max, out_min, out_max) => {\r\n  return ((num - in_min) * (out_max - out_min)) \/ (in_max - in_min) + out_min\r\n}<\/pre>\n
That’s all! hopefully, you have successfully created a blurred image-loading animation on your webpage. If you have any questions or suggestions, feel free to comment below.<\/p>\n","protected":false},"excerpt":{"rendered":"
