一段js加密代码，望JS大神提供解密思路，

不要用那些垃圾的通用的一键解密，正则表达式都被破坏了
思路放到控制台，设置个变量，把替换出去的补回来
假设代码变量为“code”，
运行最前面的初始化部分（开头到htmlFontSize函数定义之前的部分）

[JavaScript] 纯文本查看 复制代码

console.log(code.replace(/__Oxb7f82\[0x[\da-f]+\]/g,a=>{
a=`"${eval(a).replace(/"/g,"\"")}"`;
console.log(a);
return a
}))

上面一小段代码即可输出替换回字符串的代码到控制台

然后再手动删除一下垃圾代码

然后如果xxx["yyy"]这种看的不习惯就改成xxx.yyy

console.log(code.replace(/__Oxb7f82\[0x[\da-f]+\]/g,a=>{
a=`"${eval(a).replace(/"/g,"\"")}"`;
console.log(a);
return a
}).replace(/\[s*['"][^"']+['"]\s*\]/g,a=>{
a=a.trim();
a=a.substring(2,a.length-2)
console.log(a);
return "."+a
}))

然后再输出
