cartDataProducts = ;
var cartItems = 0;
$('.mini-cart-number').text(cartItems);
} else {
cartData = JSON.parse(cartData);
cartDataProducts = cartData['products'];
var cartItems = cartDataProducts.length;
$('.mini-cart-number').text(cartItems);
}
function clearCartItemes() {
localStorage.clear();
}
function renderCartItems() {
for (i = 0; i < cartDataProducts.length; i++) {
row = "<tr class='cart_item'> <td>" + i + "</td> <td class='product-thumbnail'> <a href='#'><img src='" + cartDataProducts[i]['img'] + "' alt=''></a> </td> <td class='product-name'> <a href='#'>" + cartDataProducts[i]['name'] + "</a> </td> <td class='product-price'> <span class='amount'>" + cartDataProducts[i]['price'] + "</span> </td> </tr>";
$('#cfxItem').append(row);
}
}
$("body .addcart-link, #addToCartDynamic").click(function() {

var cart = JSON.parse(localStorage.getItem('cart'));This is null. Did you want to set it to an empty array iflocalStorageis empty?
