  jQuery(function ($) {

    $('.button').on('click', function () {
        var id = $(this).data('id');

        $.ajax({
            url: '/ajax.php',
            data: {
                id: id
            },
            method: 'POST',
            success: function (html) {
                $('body').append(html);
                $(html).bPopup();
            },

请尝试此

<script>    
  jQuery(function ($) {

    $('.button').on('click', function () {
        var id = $(this).data('id');
        var qtyValue = $("input[type='text'][name='qty']").val();
        $.ajax({
            url: '/ajax.php',
            data: {
                id: id,
                quantityValue : qtyValue  
            },
            method: 'POST',
            success: function (html) {
                $('body').append(html);
                $(html).bPopup();
            },
            error: function (returnValue) {}
        });
    });


   });
</script>
