Find & replace jquery

Question

I have this code to give me a rollover on submit buttons, and I\'m trying to make it more generic:

$(\'.rollover\').hover(
            function(){ // Change          


        

Answer 1

$('.rollover').hover(
            function(){ // Change the input image's source when we "roll on"
                var t = $(this);
                t.attr('src',t.attr('src').replace(/([^.]*)\.(.*)/, "$1-over.$2"));
            },
            function(){ 
                var t= $(this);
                t.attr('src',t.attr('src').replace('-over',''));
            }
     );
