快速浏览了您的代码。 （内嵌/嵌入在主页中。）
这里有一些问题。
1.) 你几乎从不使用var。结果，您的所有变量都被提升到全局空间。
function foo() {
answer = 42;
}
foo();
现在window.foo === 43，或者如果你愿意，直接foo。
在您的一个作用域中，您还拥有use strict。结果，未定义的变量不会被提升，但您通常会得到：
Uncaught ReferenceError: somevariablename is not defined
2.) 你永远不会在 for in 循环中使用 hasOwnProperty()。始终使用：
for (x in y) {
if (y.hasOwnProperty(x)) {
....
}
}
如果是数组，请不要使用for in，但是：
var i;
for (i = 0 ; y.length ; ++i) {
}
在您的代码中，您对数组做了很多 for in。不要！
3.) 在第 352 行，您缺少分号：
html += '" onClick="">' // ««« Missing semicolon!
if (isSuccess == false) {
html += data.error_result_html;
4.) 内联 cmets。
如果脚本被一些实施不佳的压缩器内联代码压缩是一个问题：
var x = 123;
// some comment
alert(x);
可能会导致
var x = 123; // some comment alert(x);
5.) 无法读取 null 的属性“innerHTML”
可能意味着您的某些代码被乱序执行。例如。它在 DOM 准备好之前执行。据我所知，只有最后一个间隔 thing 在 jQuery 的 ready 包装之外。尝试将其添加到包装器中。
$(document).ready(function () {
...
function CheckTables() {
$("table ").each(function (index) {
$(this).find('tbody:empty').parent().hide();
$(this).find('tbody:not(:empty)').parent().show();
});
}
setInterval(CheckTables, 100);
});
您也可以尝试将 ready() 替换为：
$(window).load(function() {
});
在这两种情况下。
可能还有更多。先尝试修复数字 3。
从提取的代码中快速格式化和一些注释和变量插入等：
