Jquery 1.7.2 compatiblity issue

[mukeshyadav-cdac]

I am using jquery 1.7.2 rather than 1.4.2 .
At line no 284 in the code is having a problem
(jQuery.each(topUp.element.attr("class").split(/\s/), function(i, c) {)

topUp.element.attr("class") gives me undefined if class is not defined in 1.7.2
but it gives me empty string if I am using 1.4.2.
So I am getting Exception on this line.
I changed this line to
jQuery.each((topUp.element.attr("class") || "").split(/\s/), function(i, c) {
to resolve my problem.

I was having the same issue. I used your code but when I click on an image it became smaller, LOL. Do you have the same problem?
