cookie很实用的一个功能,可以判断某个状态,在项目中使用率极高
function setCookie(name,value) { var Days = 30; var exp = new Date(); exp.setTime(exp.getTime() + Days*24*60*60*1000); document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString(); var strsec = getsec(time); var exp = new Date(); exp.setTime(exp.getTime() + strsec*1); document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString(); } //读取cookies function getCookie(name) { var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)"); if(arr=document.cookie.match(reg)) return (unescape(arr[2])); else return null; } //删除cookies function 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(); }
