"cookies“和关闭函数的过期时间
"cookies“和关闭函数的过期时间
提问于 2018-06-16 01:54:47
我希望当我点击"Cookies“按钮时，消息不会再次显示。当"cookies“被接受时，他们就有时间存储设备了。我需要你的帮助。:)
这是一个html和js代码：
$(document).ready(function(){
setTimeout(function () {
$("#cookieConsent").fadeIn(200);
}, 4000);
$("#closeCookieConsent, .cookieConsentOK").click(function() {
$("#cookieConsent").fadeOut(200);
});<div id="cookieConsent">
<div id="closeCookieConsent">x</div>
This website is using cookies. <a href="files/c11bg_cookie_policy.pdf" target="_blank">More info</a>. <a class="cookieConsentOK">I agree!</a>
</div>

存储cookie并检查页面加载，如果它没有什么可做的话。
$(document).ready(function() {
$('#cookieConsent').hide();
if(getCookie('cookieAccepted') == null) {
setTimeout(function () {
$("#cookieConsent").fadeIn(200);
}, 4000);
$("#closeCookieConsent, .cookieConsentOK").click(function() {
setCookie('cookieAccepted', 'cookieAccepted', 90);
$("#cookieConsent").fadeOut(200);
});
}
});
function setCookie(cname, cvalue, exdays, domain) {
var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = "expires=" + d.toUTCString();
var cookieString = cname + "=" + cvalue + ";" + expires + ";path=/;";
if(domain && domain != '') {
cookieString += "domain="+domain+";"
}
document.cookie = cookieString;
}
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.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 null;

<div id="closeCookieConsent">x</div>

您可以将cookie放在用户的浏览器上，如果cookie存在，则检查页面的加载情况，如下面的代码所示。当你点击x或者点击‘我同意！’链接，则不会再次显示该消息。
您可以重新加载它不再显示的页面。
您必须删除cookie才能再次看到消息，因此我添加了一个按钮来删除cookie并重新加载页面。如果你点击"Click for delete cookie"，cookie就会消失，消息也会消失。
