Just a simple script I use to automate image rollovers that may be of use to others. Just include this javascript:
UPDATED
I felt motivated to simplify this even more according to many of the comments below. This takes advantage of html5 data attributes instead of a custom one, and eliminates the need for a special hover css class. It also eliminates the need for a temporary variable to store the current image in by using a ‘tmp’ attribute, and then removing it when finished. It also preloads the images for the rollover.
$(function() { $('img[data-hover]').hover(function() { $(this).attr('tmp', $(this).attr('src')).attr('src', $(this).attr('data-hover')).attr('data-hover', $(this).attr('tmp')).removeAttr('tmp'); }).each(function() { $('<img />').attr('src', $(this).attr('data-hover')); });; }); |
This should be used with an img element as follows:
<img src="first.gif" data-hover="second.gif" /> |
Original code
$(function() { $('.rollover').hover(function() { var currentImg = $(this).attr('src'); $(this).attr('src', $(this).attr('hover')); $(this).attr('hover', currentImg); }, function() { var currentImg = $(this).attr('src'); $(this).attr('src', $(this).attr('hover')); $(this).attr('hover', currentImg); }); }); |
This will pick up an image that looks as follows, and setup the rollover image:
<img src="first.gif" hover="second.gif" class="rollover"/> |
