Integrate magnifying glass zoom effect on website

Follow below quick steps to integrate magnifying glass style like zoom functionality on images.

Libraries

Include the magnify.css and jquery.magnify.js on along with jquery core library.

<!--CSS-->
<link rel="stylesheet" href="magnify.css">
 
<!--JS-->
<script src="//code.jquery.com/jquery-latest.min.js"></script>
<script src="jquery.magnify.js"></script>

You have complete control over the style and size of the lens by modifying magnify.css. Magnify has support for touch devices, but for a better zoom experience you can load the optional mobile plugin by uncommenting the last line above. It is recommended to load the JavaScript files at the bottom just before the closing </body> tag if possible.

HTML

The URI to the large image can be placed in the data-magnify-src attribute as shown below, or passed as the src option when calling the .magnify() function

<img src="product.jpg" class="zoom" data-magnify-src="product-large.jpg">

If the data-magnify-src attribute or src option is not used, then Magnify will try to grab the large image from the parent &lta> tag. Example:

<a href="product-large.jpg">
  <img src="product.jpg" class="zoom">
</a>

NOTE: The large image needs to have the same aspect ratio as the main image.


JS

Finally call the .magnify() function on page zoom functionality on images.

$(function() {   
  $('.zoom').magnify();
});

Destroy zoom effect

var $zoom = $('.zoom').magnify();
$zoom.destroy();

Use other default plugins function to control magnify effect

$(function() { 
 $('.zoom').magnify({
  // URI of the large image
  'src': '/images/product-large.jpg',
  // fade in/out speed
  'speed': 100, 
  // timeout for mobile
  'timeout': -1, 
  // Width of the main image
  'finalWidth': null,
  // Height of the main image
  'finalHeight': null,
  // Width of the image displayed inside the magnifying lens
  'magnifiedWidth': null,
  // Height of the image displayed inside the magnifying lens
  'magnifiedHeight': null,
  // Set this to true to keep the edge of the image within the magnifying lens
  'limitBounds': false,
  // callback
  'onload': function(){} 
 });
});
