JS cookie乱码问题，啥也不说了，上代码

function getCookie(b) {var d = b + "=";var e = document.cookie.indexOf(d);if (e == -1) {return null;}var a = document.cookie.indexOf(";", e + d.length);if (a == -1) {a = document.cookie.length;}var c = document.cookie.substring(e + d.length, a);//乱码//return unescape(c);// 解决乱码问题return decodeURI(c);}
