基于表单答案的 Javascript 计算

Question

我创建了一个包含多个输入和单选按钮的 Web 表单。需要收集每个问题的答案以计算成本。我不确定我的 JS 逻辑(尤其是与单选按钮相关的逻辑)是否正确。有人可以看看这个，看看我这样做是否正确吗？谢谢

HTML:

<div class="row">
    <div class="form-group col-md-4">
        <label for="company">Company Name*</label><br />

                </div>
</div>

这是JS:

function quoteGenerator(){
    let count = parseInt(document.getElementById('partnum').value);
    if (count > 0) {
        let size = 0;
        for (var i = 0 ; i < document.getElementsByName('files').length; i++) {
            if (document.getElementsByName('files')[i].checked) {
                    size = parseInt( document.getElementsByName('files')[i].value);
                    break;
            }
            if(size == 42){
                let newcount = count * size;
            } else if(size==0){
                for (var i = 0 ; i < document.getElementsByName('oldfiles').length; i++) {
                    if (document.getElementsByName('oldfiles')[i].checked) {
                        newsize = parseInt( document.getElementsByName('oldfiles')[i].value);
                        break;
                    }
                }
                let newcount= count*newsize;
            }
        }       
    }
    var ink = parseInt(document.getElementById('inkcoverone').value);
    var shortp = parseInt(document.getElementById('shortpress').value);
    var longp = parseInt(document.getElementById('longpress').value);
    var parentsheet = parseInt(document.getElementById('psheetnum').value);
    let inkcost1 = ((longp+shortp)/144)*.19*ink*parentsheet;

    for (var i = 0 ; i < document.getElementsByName('passsecond').length; i++) {
            if (document.getElementsByName('passsecond')[i].checked) {
                    pass2 = parseInt( document.getElementsByName('passsecond')[i].value);
                    break;
            }
    }
    var ink2 = parseInt(document.getElementById('inkcovertwo').value);
    let inkcost2 = ((longp+shortp)/144)*.19*ink2*parentsheet*pass2;

}

方程式都是基于 HTML 表单中变量的 id。方程式都是正确的，我只是不确定 totalCost 的各个组件是否放置在正确的位置，我也不确定这个计算的逻辑。单选按钮给我带来了一些问题。

我建议您看看 ng-model了解如何使用表单域。

Here是我之前编写的一个演示应用程序，应该可以让您了解如何根据表单输入进行计算。

您的 quoteGenerator 是一个没有任何 Angular 代码的 js 函数。将 $scope 注入(inject)函数或使用 controllerAs，创建 Controller 并删除所有 document.getElementsById 调用。

Here是你的代码我已经开始改进你的代码但我已经停止完成演示因为我不明白文件的计算应该如何工作。
