using on() with hover - jQuery

Question

This is what I have:

$(\'#blah\').hover(function(){
    $(\'etc\').show();
}, function(){
    $(\'etc\').hide();
});

This works just fine, now

Answer 1

It's because hover is not really a browser event, in fact its just a shorthand for calling

 $(selector).mouseenter(handlerIn).mouseleave(handlerOut);

Using with the .on('hover') form have been deprecated as of version 1.8.
