Answer 1

.text() returns string, so you have to use parseInt(value, radix) to convert the string to number.

$('#shopping-cart-button').click(function(){
    var basket_count = $('#basket_count').text();
    basket_count = parseInt(basket_count, 10) + 1;
    $('#basket_count').text(basket_count);
});
