Today I will tell you about another one useful tool of JQuery – Zoomimage plugin. It allow to reach different design ideas with images resizing.

Features

  • Preloads images
  • The images can by grouped in galleries
  • Scales the image to fit the viewport

As example, we want to animate list of your members or your image gallery.

The HTML

Here are sources of all 5 samples. As you notice – we having simple unordered list, they all quite same, only have different ‘id’ attribute.

<p>
    <a href="images/demo1_1.jpg" title="Seashell" class="example1"><img src="images/th_demo1_1.jpg" alt="Seashell" /></a>
    <a href="images/demo1_2.jpg" title="Chain" class="example1"><img src="images/th_demo1_2.jpg" alt="Chain" /></a>
    <a href="images/demo1_3.jpg" title="Coins" class="example1"><img src="images/th_demo1_3.jpg" alt="Coins" /></a>
    <a href="images/demo1_4.jpg" title="Ice" class="example1"><img src="images/th_demo1_4.jpg" alt="Ice" /></a>
    <a href="images/demo1_5.jpg" title="Grass" class="example1"><img src="images/th_demo1_5.jpg" alt="Grass" /></a>
</p>

<p>
    <a href="images/demo1_1.jpg" title="Seashell" class="example2"><img src="images/th_demo1_1.jpg" alt="Seashell" /></a>
    <a href="images/demo1_2.jpg" title="Chain" class="example2"><img src="images/th_demo1_2.jpg" alt="Chain" /></a>
    <a href="images/demo1_3.jpg" title="Coins" class="example2"><img src="images/th_demo1_3.jpg" alt="Coins" /></a>
    <a href="images/demo1_4.jpg" title="Ice" class="example2"><img src="images/th_demo1_4.jpg" alt="Ice" /></a>
    <a href="images/demo1_5.jpg" title="Grass" class="example2"><img src="images/th_demo1_5.jpg" alt="Grass" /></a>
</p>

<p>
    <a href="images/demo1_1.jpg" title="Seashell" class="example3"><img src="images/th_demo1_1.jpg" alt="Seashell" /></a>
    <a href="images/demo1_2.jpg" title="Chain" class="example3"><img src="images/th_demo1_2.jpg" alt="Chain" /></a>
    <a href="images/demo1_3.jpg" title="Coins" class="example3"><img src="images/th_demo1_3.jpg" alt="Coins" /></a>
    <a href="images/demo1_4.jpg" title="Ice" class="example3"><img src="images/th_demo1_4.jpg" alt="Ice" /></a>
    <a href="images/demo1_5.jpg" title="Grass" class="example3"><img src="images/th_demo1_5.jpg" alt="Grass" /></a>
</p>

Attaching CSS

I attached 2 external CSS files

<link rel="stylesheet" media="screen" type="text/css" href="zoomimage.css" />
<link rel="stylesheet" media="screen" type="text/css" href="custom.css" />

zoomimage.css, custom.css


Adding JQuery

I attached 3 external JS files

<script type="text/javascript" src="eye.js"></script>
<script type="text/javascript" src="utils.js"></script>
<script type="text/javascript" src="zoomimage.js"></script>

And here are additional initialization code

<script type="text/javascript">

(function($){
	var initLayout = function() {
		// example 1
		$('a.example1').zoomimage();

		// example 2
		$('a.example2').zoomimage({
			border: 20,
			centered: true,
			hideSource: true
		});

		// example 3
		$('a.example3').zoomimage({
			controlsTrigger: 'mouseover',
			className: 'custom',
			shadow: 40,
			controls: false,
			opacity: 1,
			beforeZoomIn: function(boxID) {
				$('#' + boxID)
					.find('img')
					.css('opacity', 0)
					.animate(
						{'opacity':1},
						{ duration: 600, queue: false }
					);
			},
			beforeZoomOut: function(boxID) {
				$('#' + boxID)
					.find('img')
					.css('opacity', 1)
					.animate(
						{'opacity':0},
						{ duration: 600, queue: false }
					);
			}
		});
	};

	EYE.register(initLayout, 'init');
})(jQuery)

</script>

Step 4. Images and cursors

Also we need several images and cursors for these demos:

        loading
        custom-lr
        loading
        shadow-c
        shadow-lr
        shadow
        zoomimage_next
        zoomimage_prev
        demo1_1
        demo1_2
        demo1_3
        demo1_4
        th_demo1_1
        th_demo1_2
        th_demo1_3
        th_demo1_4

zoomin.cur, zoomout.cur


For developers. Customization.

Sure that it will useful too

Invocation code

All you have to do is to select the elements in a jQuery way and call the plugin.

 $('a.myLinks').zoomimage(options);

Options

A hash of parameters. All parameters are optional.

Close all images and clear orphans

If you want to close all openend images or clear images without triggers (remvoed from DOM) then you can use ‘zoomimageClear’. The selection for this plugin should always be ‘div.zoomimage’.

$('div.zooimage').zoomimageClear();

    • Hi vinod,
      Try to update both: jQuery library and the plugin itself. They might updated it for the latest jquery version.

  1. $(document).ready(function()
    {
    $(‘#image’).click(function()
    {
    $(‘#image’).animate({ width: ’800px’ , height: ’700px’ });
    });
