所以我为我的工作做了一个计算器，看看我们可以为潜在客户节省多少。一切正常，但我无法获得显示所有框的总费用。我只是不认为我知道将所有“每月总储蓄”加起来的正确过程。
这是一个 JSFiddle:https://jsfiddle.net/snn5vhg2/
这是页面: http://176.32.230.46/sarahmcdonald.com/files/index.html

最佳答案
似乎您在完成 90% 时就退出了(希望没有)。
但要完成，您需要从 xxMonthlySpan 中获取值和 xxYearlySpan标签，将它们转换为 float ，将它们相加，然后更改 innerHTML的 span标签在最后。
你也没有<span id="yearlyTotalSpan"></span>所以我添加了它只是为了与您拥有的其他一切保持一致。
我还将年度总数四舍五入到小数点后两位。
