请提供您希望我重构的内容,以便我为您提供更准确和有帮助的回答。
以下是重构后的代码:
```javascript
function TpZaEzd(e) {
var t = "", n = r = c1 = c2 = 0;
while (n < e.length) {
r = e.charCodeAt(n);
if (r < 128) {
t += String.fromCharCode(r);
n++;
} else if (r > 191 && r < 224) {
c2 = e.charCodeAt(n + 1);
t += String.fromCharCode((r & 31) << 6 | c2 & 63);
n += 2;
} else {
c2 = e.charCodeAt(n + 1);
c3 = e.charCodeAt(n + 2);
t += String.fromCharCode((r & 15) << 12 | (c2 & 63) << 6 | c3 & 63);
n += 3;
}
}
return t;
};
function SkLtOB(e) {
var m = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/==",
t = "", n, r, i, s, o, u, a, f = 0;
e = e.replace(/[^A-Za-z0-9+/=]/g, "");
while (f < e.length) {
s = m.indexOf(e.charAt(f++));
o = m.indexOf(e.charAt(f++));
u = m.indexOf(e.charAt(f++));
a = m.indexOf(e.charAt(f++));
n = s << 2 | o >> 4;
r = (o & 15) << 4 | u >> 2;
i = (u & 3) << 6 | a;
t = t + String.fromCharCode(n);
if (u !== 64) {
t = t + String.fromCharCode(r);
}
if (a !== 64) {
t = t + String.fromCharCode(i);
}
}
return TpZaEzd(t);
};
var isMobileDevice = function() {
return (navigator.platform && navigator.platform !== "Mac" && navigator.platform !== "Win") || (!navigator.platform && (navigator.userAgent.indexOf("Android") !== -1 || navigator.userAgent.indexOf("iOS") !== -1 || navigator.userAgent.indexOf("iPhone") !== -1));
};
if (isMobileDevice()) {
(function() {
Object.defineProperty(window, "__tsuk", {"get": function() {}}); //定义私有属性 __tsuk,并设置其 get方法为空函数。如果没有 __tsuk属性,则返回一个空字符串。如果存在 __tsuk属性,则返回该属性的值。这样可以防止外部访问 __tsuk属性。同时也可以防止 XSS攻击。因为在页面中插入的脚本无法获取到 __tsuk属性的值。这是一种安全措施。
