答案 0 :(得分：0)
尝试将大量函数重构为较小的部分（您可以使用标准函数添加选项元素），这意味着更少的复制/粘贴代码。
然后，您可以通过这些函数添加简单的调试语句，以查看发生的情况。
答案 1 :(得分：0)
e1.setAttribute("onclick","javascript:SelectSubCat(this);");
我认为这条线可能是原因。请看以下内容（第一行使用"onchange"，但JS添加的行使用"onclick" ...）：
document.getElementById("Category[0]").onchange // the first row
>> function()
但是，
document.getElementById("Category[1]").onclick // the second row
>> "SelectSubCat(this);"
即。 Internet Explorer将onclick设置为字符串！ （顺便说一句，添加监听器的推荐方法是使用addEventListener（但IE忽略它并使用自己的attachEvent！）。无论如何，有一种DOM 0方式可以正常工作（在IE和Fx：element.onevent。使用此方法时，您不必将this传递给函数，只需在调用函数时将（this =单击的元素替换为上一行）：
e1.onchange = SelectSubCat;
但是，您必须更改第一行调用SelectSubCat的方式，并在函数中使用this而不是control_value。
最后一件事，类似的一句话：
el.setAttribute("onblur","javascript:check_numeric(this)");
你必须在这里做同样的事情。
你应该听听所有人shouting at you你的功能有多糟糕（可能有些数组可能有助于清理代码的某些部分）。而且（最后一个“和”:)，如果没有JS，这个页面将无法运行，因此会被破坏。
（有关JS中事件的更多信息，请参阅Introduction to Events。）
答案 2 :(得分：-1)
没有读完整件事 - 你粘贴了远太多的代码 - 但我会猜测这个问题。
IE有一个众所周知的问题，即它无法使用DOM方法动态添加表格单元格。使用innerHTML代替，这有效。
