debug看看416行的node为什么会是null呗 var node = document.getElementById(HMInitToggle.arguments);
debug这一行的代码,应该是HMInitToggle.arguments这一行没有获取到对应的值,导致byId找不到元素 var node = document.getElementById(HMInitToggle.arguments);问题就在这里，HMInitToggle.arguments)这里如果是空的你就获取不到元素
if(HMInitToggle.arguments)){
var node = document.getElementById(HMInitToggle.arguments);
用到node操作放到这里
} 感谢两位指教，发现是某款软件的皮肤（把它改扩展名为RAR，竟然需要密码，没有密码也就得不到上面的JS文件了）
于是我灵机一动，网上下载一个老版本的皮肤，挪来用，再生成就不会出现错误了。{:301_988:} 吾爱的大神真多，总有人帮答疑！ 吾爱的大神真多，总有人帮答疑！ 不过发现有个新的严重问题，中文乱码了。 冥界3大法王 发表于 2024-11-18 10:26
不过发现有个新的严重问题，中文乱码了。
中文乱码跟你文件保存的编码格式有关系。 这应该是浏览器版本故障？
