Instructions

Zoom appends html inside the element it is assigned to, so that element has to be able to accept html, like <a>, <span>, <li>, <div>, etc. This excludes <img> elements (see below).

// Example:
$(document).ready(function(){
  $('a.photo').zoom({url: 'photo-big.jpg'});
});

// Using Colorbox with Zoom
$(document).ready(function(){
  $('a.photo').zoom({
    url: 'photo-big.jpg', 
    callback: function(){
      $(this).colorbox({href: this.src});
    }
  });
});

 

 

To use zoom with img elements, they will need to be wrapped with another element. It is impossible to read some layout related CSS styles from JavaScript (percent-based width and height, margins set to auto, etc.) so the safe thing to do is to defer this change to individual site owners. The following is all that is needed in some cases:

$(document).ready(function(){
  $('img')
    .wrap('<span style="display:inline-block"></span>')
    .css('display', 'block')
    .parent()
    .zoom();
});

 

 

Removing Zoom

Trigger the zoom.destroy event to remove zoom from an element:

$('#example').zoom(); // add zoom
$('#example').trigger('zoom.destroy'); // remove zoom

 

 

Settings

Property Default Description

url	false	The url of the large photo to be displayed. If no url is provided, zoom uses the src of the first child IMG element inside the element it is assigned to.
on	'mouseover'	The type of event that triggers zooming. Choose from mouseover, grab, click, or toggle.
duration	120	The fadeIn/fadeOut speed of the large image.
target	false	A selector or DOM element that should be used as the parent container for the zoomed image.
touch	true	Enables interaction via touch events.
magnify	1	This value is multiplied against the full size of the zoomed image. The default value is 1, meaning the zoomed image should be at 100% of its natural width and height.
callback	false	A function to be called when the image has loaded. Inside the function, `this` references the image element.
onZoomIn	false	A function to be called when the image has zoomed in. Inside the function, `this` references the image element.
onZoomOut	false	A function to be called when the image has zoomed out. Inside the function, `this` references the image element.
