javascript - jQuery function .on works in 1.8.3 but not in 1.9.1

Question

I have a function that works with jQuery 1.8.3 but when I upgrade to 1.9.1 it's not working anymore, but there's no change in documentation. Does somebody know how to fix this?

$(document).on("hover", "#cart-left", function(){
    $("#cart").addClass('active');
});

Thanks for support!

In 1.9.1 you should use mouseover

$(document).on("mouseover", "#cart-left", function(){
    $("#cart").addClass('active');
});
