js操作Cookie的方法

function SetCookie(name, value, expires, path, domain, secure) { var today = new Date(); today.setTime(today.getTime()); if(expires) { expires *= 86400000; } 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 GetCookie(name) { var cookies = document.cookie.split( ';' ); var cookie = '';

for(var i=0; i<cookies.length; i++) { cookie = cookies[i].split('='); if(cookie[0].replace(/^\s+|\s+$/g, '') == name) { return (cookie.length <= 1) ? "" : unescape(cookie[1].replace(/^\s+|\s+$/g, '')); } } return null;}

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