PHP 讀寫cookie的語句:
setcookie("user", "Lilu", time()+3600);echo $_COOKIE["user"];
javascript讀寫cookie代碼:
function SetCookie(name,value)//兩個參數,一個是cookie的名子,一個是值{ var Days = 30; //此 cookie 將被儲存 30 天 var exp = new Date(); //new Date("December 31, 9998"); exp.setTime(exp.getTime() + Days*24*60*60*1000); document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();}function getCookie(name)//取cookies函數 { var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)")); if(arr != null) return unescape(arr[2]); return null;}function delCookie(name)//刪除cookie{ var exp = new Date(); exp.setTime(exp.getTime() - 1); var cval=getCookie(name); if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();}SetCookie ("lilu", "it‘s me")alert(getCookie(‘lilu‘));
頁面用不同的瀏覽器訪問cookie就存放在不同的地方,比如IE瀏覽器的cookie存放在
C:\Users\[your computer name]\AppData\Roaming\Microsoft\Windows\Cookies
在同一瀏覽器下 javascript產生的cookie和php產生的cookie可以互相訪問比如:
alert(getCookie(‘user‘));
echo $_COOKIE["lilu"];
