问题描述：

如题，需要在 java 代码中执行 js, 使用的是 java8 自带引擎； ScriptEngine engine = new ScriptEngineManager().getEngineByName("nashorn"); 解析如下 js 代码时，发现结果 与 浏览器执行结果不一致；

js:

 function DeCode() { this.OO0O00OO00OO = function (a, b) { return b > 0 ? a.substring(0, b) : null; }, this.OO00OO0O00O0 = function (a, b) { return a.length - b >= 0 && a.length >= 0 && a.length - b

b.charCodeAt(c).toString(); } for (d = Math.floor(k.length / 5), e = parseInt(k.charAt(d) + k.charAt(2 * d) + k.charAt(3 * d) + k.charAt(4 * d) + k.charAt(5 * d)), f = Math.round(b.length / 2), g = Math.pow(2, 31) - 1, h = parseInt(a.substring(a.length - 8, a.length), 16), a = a.substring(0, a.length - 8), k += h; k.length > 10; ) { k = (parseInt(k.substring(0, 10)) + parseInt(k.substring(10, k.length))).toString(); } for (k = (e * k + f) % g, i = "", j = "", c = 0; c < a.length; c += 2) { i = parseInt(parseInt(a.substring(c, c + 2), 16) ^ Math.floor(255 * (k / g))), j += String.fromCharCode(i), k = (e * k + f) % g; } return j; }, this.O0O000O0OO00O = function () { var
