博客出现弹出式窗口1次

Question

需要你的帮助。 我想让我的博客仅在1个IP地址上弹出一次新标签。 我找到了代码，并尝试应用但不起作用。 对不起，我不是很好。 我在这里找到的代码：

function Set_Cookie(name, value, expires, path, domain, secure) {
    var today = new Date();
    today.setTime(today.getTime());

    if (expires) {
        expires = expires * 1000 * 60 * 60 * 12;
    }
    var expires_date = new Date(today.getTime() + (expires));

    document.cookie = name + "=" + escape(value) +
    ((expires) ? ";expires=" + expires_date.toGMTString() : "") +
    ((path) ? ";path=" + path : "") +
    ((domain) ? ";domain=" + domain : "") +
    ((secure) ? ";secure" : "");
}

function Get_Cookie(name) {

    var start = document.cookie.indexOf(name + "=");
    var len = start + name.length + 1;
    if ((!start) &&
    (name != document.cookie.substring(0, name.length))) {
        return null;
    }
    if (start == -1) return null;
    var end = document.cookie.indexOf(";", len);
    if (end == -1) end = document.cookie.length;
    return unescape(document.cookie.substring(len, end));
}

function Delete_Cookie(name, path, domain) {
    if (Get_Cookie(name)) document.cookie = name + "=" +
    ((path) ? ";path=" + path : "") +
    ((domain) ? ";domain=" + domain : "") +
    ";expires=Thu, 01-Jan-1970 00:00:01 GMT";
}

function popunder() {
    if (Get_Cookie('vnsTraGopLT6')) {
        return false;
    } else {
        Set_Cookie('vnsTraGopLT6', 'vnsTraGopLT PopUnder', '1', '/', '', '');
        urls = ["http://noithathopphat.vn"]
        var url = urls[Math.floor(Math.random() * urls.length)]
        params = 'width=' + screen.width;
        params += ', height=' + screen.height;
        params += ', top=0, left=0,scrollbars=yes'
        params += ', fullscreen=yes';

        pop = window.open(url, 'window', params).blur();
        window.focus();
        return false;
    }
}
