<script type="text/javascript" src="{{ asset('jquery.js') }}"></script>

这是我用来计算总价的jquery脚本，我尝试与控制器一起使用，但是它似乎不起作用，加上在不重新加载页面的情况下更好地计算数量

<script type="text/javascript">

    $(function () {
        $('[id="remove"]').on('click', function(e) {
            location.reload();
            var href = this.href;
            e.preventDefault();
            $.ajax({
                type: "POST",
                url: href,
                dataType: 'json',
                success: function(json) {

                    console.log(json);
                }
            });
        });
    });

    function addAction(ok)
    {

        var plus=$('#q'+ok).val();
        $('#q'+ok).val(parseInt(plus)+1);
        var quantity=parseInt($('#q'+ok).val());
        var price1 =parseFloat($('#price'+ok).text());

        $('#total'+ok).html((quantity*price1).toFixed(2));
        var total =parseFloat($('#total').text())+price1;
        $('#total').html(total.toFixed(2));
    }

    function sousAction(id)
    {

        var moin=$('#q'+id).val();
        if(((parseInt(moin) - 1)>0)) {
            $('#q'+id).val(parseInt(moin) - 1);
            var quantity=parseInt($('#q'+id).val());
            var price1 =parseFloat($('#price'+id).text());
            $('#total'+id).html((quantity*price1).toFixed(2));
            var total =parseFloat($('#total').text())-price1;
            $('#total').html(total.toFixed(2));
        }

    }



</script>

Answer 1

两个按钮上的ID相同

由于您要添加功能，因此我没有找到任何带有id（'＃price'+ ok）的标签

无论如何，问题实际上在price1变量中存在您仍然需要更改一行

function addAction(ok)
{
    var plus=$('#q'+ok).val();
    $('#q'+ok).val(parseInt(plus)+1);
    var quantity=parseInt($('#q'+ok).val());
 //  var price1 =parseFloat($('#price'+ok).text()); commented original
    var price1 =parseFloat($('#price'+ok).val()); //added this line

    $('#total'+ok).html((quantity*price1).toFixed(2));
    var total =parseFloat($('#total').text())+price1;
    $('#total').html(total.toFixed(2));
}

希望这可以解决您的问题

标签中的值显示为NaN
