Javascript 关于形状计算的问题

这是较长表单的一小部分（为清晰起见，添加了粉色、绿色和黄色框/箭头）：

                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);
                }

原件：

                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);
                }

标记：

                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);
                }

基本上-当数字输入到Quarter->checks（粉色框）中时，值会自动求和并自动填充只读字段“Total Cash”（这已经起作用）。然后，一旦“退款已付”字段输入了值（包括零），它将自动计算“现金总额”并填充“最终总额”字段-每个列都是单独的。这是可行的——但我希望我不必强迫用户在退款中输入值，除非有值。最后-我还需要“存款”和“经理站”列中的“最终总计”，以自动汇总到“存款总计”，这似乎根本不起作用

                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);
                }

最后，我试图实现一个按钮来重新计算所有的总数，然后他们点击“提交”将其转换成PDF格式，我也被难倒了。它有名称和ID

calc

——但我愿意接受任何关于这方面的最佳实践解决方案。我非常乐意做大量的修改——作为一个新手，很多修改都采用了“我的裤子的座位”编码

                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);
                }

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

                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);
                }

                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);
                }

这是可行的——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

                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);
                }

这都是你想要的吗？ 请尝试下面的代码

                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);
                }

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/某处修改：向每个事件添加上述函数

                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);
                }

            $(".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/将“$（“.depFinalFactor”）.keyup（function（）”处的函数替换为以下内容

                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);
                }

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

我所做的是将汇总总值的函数移动到一个函数中，每次用户开始在表中的一个字段上输入数字时，我都会重用它。所有这些都在代码中，仅此而已

                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);
                }

编辑：我也在fiddle上更新了你的代码。

如果有人想玩，这里有一把小提琴：修复了！你是个救生员！

                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);
                }
