IE8没有使用javascript刷新值

Question

我正在使用javascirpt和ajax来添加/更新/删除结帐篮子中的物品，
除IE8外，所有浏览器的外观和效果都很好。

在IE8上，当我添加/更新/删除项目到篮子时，我需要刷新篮子的窗口以获取值更改，是不是像其他浏览器那样动态地执行。它适用于IE9和IE10

这是我用于购物篮的功能

$('#add_to_basket').click(function(e) {
        e.preventDefault();
        var product_id = $('#add_to_basket').attr('rel');
        var quentity = $('select[name="quantity"]').val();
        var size = $('select[name="size"]').val();
        var colour = $('select[name="colour"]').val();
        var error = 0;

        if (quentity == '') {
            $('select[name="quantity"]').siblings('.selectBox-dropdown').eq(0).addClass('error');
            error = 1;
        }

        if (size == '') {
            $('select[name="size"]').siblings('.selectBox-dropdown').eq(1).addClass('error');
            error = 1;
        }

        if (colour == '') {
            $('select[name="colour"]').siblings('.selectBox-dropdown').eq(2).addClass('error');
            error = 1;
        }

        if (error === 0) {
