Guide to implement jQuery image preview on your page
- Your page should point to external jquery library and to imgpreview plugin
<script src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js" type="text/javascript"></script>
<script src="http://plugins.jquery.com/files/imgpreview.min.0.22.jquery.js.txt" type="text/javascript"></script> - We need some HTML code, one unordered list with one list item. This list item must have link to image
<ul id="first">
<li><a href='http://www.freefoto.com/images/15/10/15_10_70_thumb.jpg' rel="nofollow">The Sunset</a>
</li>
</ul> - Add jQuery code which instruct that when mouse pointer is over unordered list (ul) with id "first", method imgPreview is called. This method shows the image.
<script type="text/javascript">
$(document).ready(function(){
$('ul#first a').imgPreview({
imgCSS: { width: 100 }
});
});
</script>- imgCSS: { width: 100 } - width is determined.
- And that's it, demo works!!!
