表单计算的问题

这是更长形式的一小部分(为了清晰起见,添加了粉红色,绿色和黄色框/箭头):

基本上 - 将数字输入季度 - >检查(粉红色框),值自动求和并自动填充只读字段“总现金”(这已经在工作)。然后,一旦“退款付款”字段输入了一个值(包括零),它就会自动与“总现金”相加并填充“最终总计”字段 - 这对于每一列都是独立的。这有效 - 但我希望我不必强迫用户在退款付费中输入值,除非有值。最后 - 我还需要从“存款”和“经理站”栏目中的“最终总计”到自动汇总到“总存款”这似乎根本不起作用......

最后 - 我试图实现一个按钮来重新计算所有总数,然后再单击“提交”将其转换为PDF - 我也很难过。它具有名称和ID calc - 我对任何最佳实践解决方案都持开放态度。我很乐意做出大量改动 - 作为一个新手,很多人都采用“我的裤子座位”编码。

我对Javascript和JQuery非常陌生 - 所以请温柔一点?以下代码(无论如何,与此问题相关的部分):

使用Javascript / JQuery的

有效 - 但我希望我不必强迫用户输入值   在退款中支付,除非有价值。

这就是你想要的吗? 试试下面的代码

1 /添加此功能

                function showAllTotal(){
                    var sum = 0;

                    $(".depFinalFactor").each(function() {
                    //add only if the value is number
                        if(!isNaN(this.value) && this.value.length!=0) {
                            sum += parseFloat(this.value);
                        }
                    });     


                    mySum = sum.toFixed(2);

                    if (mySum == $("#moneyAccountedFor").val()) {
                        $("#totalToDeposit").css("color", "green");
                    } else {
                        $("#totalToDeposit").css("color", "red");
                    }

                    $("#depFinalTotal").val(mySum);
                    $("#totalToDeposit").text(mySum);
                }

2 /修改某处:将上述功能添加到每个事件

            $(".dep").each(function() {
                    $(this).keyup(function(){
                        calculateSumForInput(".dep", "#depTotal");
                        showAllTotal();
                    });         
                });
                $(".man").each(function() {
                    $(this).keyup(function(){
                        calculateSumForInput(".man", "#manTotal");
                        showAllTotal();
                    });
                });
                $(".safe").each(function() {
                    $(this).keyup(function(){
                        calculateSumForInput(".safe", "#safeTotal");
                        showAllTotal();
                    });
                });

3 /替换“$(”。depFinalFactor“)中的函数.keyup(function()”with below

            $(".depFinalFactor").keyup(function() {
                    showAllTotal();
            });

我所做的是将总值总结的函数移动到函数中,并且每次用户开始在表中的一个字段上输入数字时重复使用它。一切都在您的代码中,仅此而已!

编辑:我也在小提琴上更新了你的代码。
