cookie 的相关操作

// 设置cookiefunction setCookie(name, value) { var curDate = new Date(); //当前时间戳 var curTamp = curDate.getTime(); //当日凌晨的时间戳,减去一毫秒是为了防止后续得到的时间不会达到00:00:00的状态 var curWeeHours = new Date(curDate.toLocaleDateString()).getTime() - 1; //当日已经过去的时间（毫秒） var passedTamp = curTamp - curWeeHours; //当日剩余时间 var leftTamp = 24 * 60 * 60 * 1000 - passedTamp; var leftTime = new Date(); leftTime.setTime(leftTamp + curTamp); document.cookie = name + "=" + escape(value) + ";expires=" + leftTime.toGMTString();}

//删除cookiefunction delCookie(name) { var exp = new Date(); exp.setTime(exp.getTime() - 1); var cval = getCookie(name); if (cval != null) document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();}

// 取出cookiefunction getCookie(name) { var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)"); if (arr = document.cookie.match(reg)) return unescape(arr[2]); else return null;}
