JS cookie中文乱码解决方法

复制代码 代码如下:
function Setcookie(name, value) {
        var exp = new Date();
        exp.setTime(exp.getTime() + 3 * 24 * 60 * 60 * 1000); //3天过期
        document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString();
        return true;
    };

    function getcookie(name) {
        var arr = document.cookie.match(new RegExp("(^| )" + name + "=([^;]*)(;|$)"));
        if (arr != null) return arr[2]; return null;
    };

复制代码 代码如下:
 var currentServiceAliasName = getcookie("appName");
        var displayName = "";
        if (currentServiceAliasName != null && currentServiceAliasName != "" && currentServiceAliasName != "undefined")
            displayName = decodeURIComponent(currentServiceAliasName) + " . " + counterName;
        else
        displayName = counterName;

decodeURIComponent 用这个转换一下
