cookie

最近任务要求某个项目有多个主题，要求某个主题不出现广告

//cookie
function setCookie(cname, cvalue, exdays) {//设置cookie方法
    var d = new Date();//获取当前时间
    d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));//格式化为cookie识别的时间
    var expires = "expires=" + d.toGMTString();
    document.cookie = cname + "=" + cvalue + "; " + expires;//设置cookie
}

function getCookie(cname) {//获取cookie方法
    var name = cname + "=";
    var ca = document.cookie.split(';');//将获得的cookie以"分号"为标识 将cookie保存到ca的数组中
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i].trim();
        if (c.indexOf(name) == 0) { return c.substring(name.length, c.length); }
    }
    return "";
}

function checkCookie() {
    var theme = getCookie("theme_bazihehun");
    if (theme == "30") {
        $("#publicFydNew").hide();
    }
}
checkCookie()
