未捕获的TypeError：无法调用未定义的方法'Runme'

标签： javascript

我一直在检查这个问题，但我仍然无法弄清楚什么是错的。它应该取得我的成绩，并吐出我的津贴。之前它正在工作，但JSfiddle搞砸了，现在它还有其他问题。任何人都可以说出错了吗？ 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 OSS = document.personal.OSS;
    var Elec1 = document.personal.Elec1;

    var Elem2 = document.personal.Elec2;
    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;
            }
        }
    };
    Calc(Mathematics, OMathematics);
    Calc(Sci, OSci);
    Calc(ELA, OELA);
    Calc(SS, OSS);
    Calc(Elec1, Elec1);
    Calc(Elec2, Elec2);
    Calc(Elec3, Elec3);
    Calc(Elem1, Elem1);
    Calc(Elem2, Elem2);
    Calc(Elem3, Elem3);
    alert(Owed);
};

嗯，首先你需要一个<form>元素，这个元素显然已被注释掉了。

其他说明：
确保您始终使用相同的案例。 ＆＃34;欠款＆＃34; ！=＆＃34;欠＆＃34;。
onClick应该是＆＃34; onclick＆＃34;，尽管大多数浏览器都可以使用它。

答案 1 :(得分：0)

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

会失败，因为没有这样的表格，无论如何都不会有Runme方法。

document.personal...

会失败，因为没有这样的事情。

尝试删除对伪造表单的引用，并替换

的所有用法 
document.personal.inputName

与

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