我刚刚将数字格式化为以逗号显示，但现在我的计算器不起作用？

Question

我正在构建一个我以前提出问题的计算器，请参阅上一个链接：构建利率计算器，但是它不会产生图形

我希望某些字段在输入时出现在逗号上，我在这里找到了一些代码，它似乎可以使用格式，但是现在计算刚刚返回NAN。

有什么想法为什么添加逗号会阻止它工作？

这是我用来添加逗号的代码，计算器的代码在上一个链接上：

html：

    <div class="col-md-10 col-md-offset-1 form-body form-group">
                <h2 class="form-heading">Find out how much your mortgage will cost</h2>

计算器JS：

    function calculate() {
var pp = document.getElementById("pp").value;
var dp = document.getElementById("dp").value;
var mt = document.getElementById("mt").value;
var ir = document.getElementById("ir").value;
var result = document.getElementById("result");
var la = parseInt(pp.replace(/,/g, ""), 10) - parseInt(dp.replace(/,/g, ""), 10);
var intRate = (ir/100)/12;
var months = mt * 12;
var monthlyPayment = ((((la*intRate)/(1-Math.pow(1+intRate,(-1*months)))*100)/100).toFixed(2));
result.innerHTML = "£" + monthlyPayment.replace(/B(?=(d{3})+(?!d))/g, ",");
    }
    function depositValue() {
    var pp = document.getElementById("pp").value;
    var percent = document.getElementById("percent").value;
    var dp = document.getElementById("dp");
    var dpValue = (parseInt(percent.replace(/,/g, ""), 10) / 100) * parseInt(pp.replace(/,/g, ""), 10);
    dp.value = dpValue;
    }
    function depositPercent() {
    var pp = document.getElementById("pp").value;
    var dp = document.getElementById("dp").value;
    var percent = document.getElementById("percent");
    var dpPercent = (parseInt(dp.replace(/,/g, ""), 10) / parseInt(pp.replace(/,/g, ""), 10) * 100).toFixed(0);
    percent.value = dpPercent;
    }

逗号JS(在另一个文件中(：

    $('input.comma').keyup(function(event) {
    // skip for arrow keys
    if(event.which >= 37 && event.which <= 40) return;
    // format number
    $(this).val(function(index, value) {
    return value
    .replace(/D/g, "")
    .replace(/B(?=(d{3})+(?!d))/g, ",")
    ;
    });
    });

添加逗号的那一刻，它不再是一个数字，而是字符串。当您进行计算时，您必须通过在处理前将它们剥离来考虑。
