Попробуйте так:
(function ($) {
$(document).ready(function () {
var filterList = {
init: function () {
$('#portfoliolist').mixitup({
targetSelector: '.portfolio',
filterSelector: '.filter',
effects: ['fade'],
easing: 'snap',
// call the hover effect
onMixEnd: filterList.hoverEffect()
})
},
hoverEffect: function () {
$('#portfoliolist .portfolio').hover(
function () {
$(this).find('.label').stop().animate({bottom: 0}, 200, 'easeOutQuad');
$(this).find('img').stop().animate({top: -30}, 500, 'easeOutQuad');
},
function () {
$(this).find('.label').stop().animate({bottom: -40}, 200, 'easeInQuad');
$(this).find('img').stop().animate({top: 0}, 300, 'easeOutQuad');
}
);
}
};
filterList.init();
});
})(jQuery);
