我要添加Cookie，显示一次仅在加载时弹出一次，而Cookie在1小时后过期

我尝试了很多文章，但也许​​我确实知道如何以正确的方式进行设置

任何人都可以帮我解决这个问题：）

1 个答案:

答案 0 :(得分：0)

您可以使用我在代码末尾添加的这两个函数来获取和设置cookie。 Cookie会按照您在60分钟内所说的那样过期。 页面加载时，我们检查是否可以获取所需的Cookie。如果可以的话，我们将以其他方式隐藏弹出窗口。

if(getCookie("age") != "")
{
$('#age-verify').addClass('hidden');
}
overAge = function () {
  setCookie("age", "overAge");
  $('#age-verify').addClass('hidden');
}

underAge = function () {
  $('#age-verify').addClass('under');
}

goBack = function () {
    window.history.back();
}

function setCookie(cname, cvalue) {
    var d = new Date();
    d.setTime(d.getTime() + (60 * 1000));
    var expires = "expires=" + d.toGMTString();
    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}

function getCookie(cname) {
    var name = cname + "=";
    var decodedCookie = decodeURIComponent(document.cookie);
    var ca = decodedCookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
