Can I store some variable into the hover function?
Question by markzzz
Seems that I can’t store the linguettaCorrente variable into the hover handler :
$('.navigatore_blocco').hover(
var linguettaCorrente=$(this).find('linguetta');
function() {
linguettaCorrente.animate( { height: 33 }, 600);
},
function() {
linguettaCorrente.animate( { height: 23 }, 600);
}
);
why? And how can I store it?

Declare the same var outside the hover and define it inside.
var linguettaCorrente = null;
$('.navigatore_blocco').hover(
function() {
linguettaCorrente = $(this).find('linguetta');
linguettaCorrente.animate( { height: 33 }, 600);
},
function() {
linguettaCorrente.animate( { height: 23 }, 600);
}
);
.hover function takes 2 argument and those 2 are functions. It cannot be anything else.

Why dont you use .data() to store the needed data?
$('.navigatore_blocco').hover(
var linguettaCorrente=$(this).find('linguetta');
$(this).data('linguetaaCorrente', linguettaCorrente);
....
);
