这个问题本周有问题。我们正在创建一个新站点，因为当前站点有些过时了。当前站点上有一系列运行良好的财务计算器。
在将脚本和内容传输到新的wordpress网站时，我们收到一条错误消息，使它无法正常工作。
我们得到的错误是：
TypeError: document.formc is undefined[Learn More] accounting-calc.js:7:3

我敢肯定这很简单，但是我还没有解决。
起初我以为formc是一个错字，但在它可以工作的原始站点上是完全一样的。
答案 0 :(得分：1)
您缺少表单上的name属性。
console.log(document.formc)<form id="formc" name="formc">
