Js操作Cookie的代码,下边的代码内有详细注释,这里就不再多说了,直接上代码:
/* *设置与获取Cookie */ var Cookie = {} //写入Cookie,key为键,value是值 //duration过期时间(天为单位,默认1天) Cookie.write = function (key, value, duration) { Cookie.remove(key); var d = new Date(); if (duration <= 0) duration = 1; d.setTime(d.getTime() + 1000 * 60 * 60 * 24 * duration); document.cookie = key + "=" + encodeURI(value) + "; expires=" + d.toGMTString() + ";path=/"; }; //移除Cookie,key为键 Cookie.remove = function (key) { var d = new Date(); if (Cookie.read(key) != "") { d.setTime(d.getTime() - (86400 * 1000 * 1)); document.cookie = key + "=;expires=" + d.toGMTString(); } }; //更多教程:Veryhuo.Com //读取Cookie,key是键 //不存在返回空字符串"" Cookie.read = function (key) { var arr = document.cookie.match(new RegExp("(^| )" + key + "=([^;]*)(;|$)")); if (arr != null) return decodeURIComponent(arr[2]); return ""; }; (编辑:好传媒网)
