[解决办法]
/*eval()函数 这个函数可以把一个字符串当作一个JavaScript表达式一样去执行它。 举个小例子： */ var the_unevaled_answer = "2 + 3"; //这里没有eval(); var the_evaled_answer = eval("2 + 3"); //这里把eval()覆给the_evaled_answer，注意有没eval()的区别 alert("the un-evaled answer is " + the_unevaled_answer + " and the evaled answer is " + the_evaled_answer);
[解决办法]
这是用来干嘛的哦。搞得是英文又不是英文的。
[解决办法]
eval 计算一个表达式
那段代码是混淆后的代码。
可以找个js 美化工具，重新排下版，就好读了

[解决办法]
eval是强制执行传入的字符串参数,被指不安全很多年了,跟之前的go to什么的差不多 该被废弃的东西.
一般在压缩过的js或是混淆的js里能看到.参数名 方法名都被简化成了abcdef什么的.
匿名函数一般后面肯定要有个()来执行.可以大概看一下闭包
eg.
1.(function(n){alert(a);})(123);
2.(function(n){
alert(n)
(function(n){
alert(n);
})(n+1);
})(123);
