}

}
// now perform the actual action you want to do only when mouse is leaving the DIV
}
var elem = $('#some-id');
elem.mouseover(function () {
// Some code here
}).mouseout(function (event) {
var e = event.toElement || event.relatedTarget;
if (elem.has(e).length > 0) return;

});

//check for all children levels (checking from bottom up)

if(e.preventDefault) e.preventDefault();
return false;
}

}
//Do something u need here
