我已经对此进行了一段时间的错误检查，但我仍然无法弄清楚出了什么问题。它应该记我的成绩，并吐出我的零用钱。它以前可以工作，但是 JSfiddle 把它搞砸了，现在它遇到了其他问题。谁能告诉我出了什么问题？代码：

<head>
<script>
alert('loaded');
function Runme() {
    alert("running");
    document.forms["form"].Runme();
    var Mathematics = document.personal.Mathematics;
    var OMathematics = document.personal.OMathematics;
    var Sci = document.personal.Sci;
    var OSci = document.personal.OSci;
    var ELA = document.personal.ELA;
    var OELA = document.personal.OELA;
    var SS = document.personal.SS;

    var OElem2 = document.personal.OElec2;
    var Elem3 = document.personal.Elec3;
    var OElem3 = document.personal.OElec3;
    var Owed = 0;
    var Calc = function(n, o) {
        if (n >= 90) {
            Owed = Owed + 1;
            if (n >= 95) {
                Owed = Owed + 1;
            }
        }
        else if (owed >= 80) {
            Owed = Owed + 0.5;
        }
        if (n > o) {
            Owed = Owed + 0.5;
        }
        if (n < o) {
            if (n > 95) {
                Owed = Owed - 0.25;
            }
        }

嗯，首先你需要一个<form>元素，它显然已经被注释掉了。

其他注意事项：
确保始终使用相同的案例。“欠”！=“欠”。
onClick 应该是“onclick”，尽管大多数浏览器都允许它工作。

document.forms["form"].Runme();

会失败，因为没有这种形式，而且Runme无论如何它也没有方法。

document.personal...

将失败，因为没有这样的事情。

尝试摆脱对虚假表单的引用，并替换所有使用

document.personal.inputName

和

document.getElementsByName("inputName")[0].value
