JS操作Cookie大全

SCRIPT language=javascriptfunction setCookies(name,value){ var Days =
30; //此 cookie 将被保存 30 天 var exp= new Date(); //new Date(December
31, 9998); exp.setTime(exp.getTime() + Days*24*60*澳门新葡亰3522平台游戏,60*1000);
document.cookie = name + =+ escape(value) +;expire*=+
**p.toGMTString();}function getCookies(name){ var arr =
document.cookie.match(new RegExp((^| )+name+=([^;]*)(;|$))); if(arr
!= null) return unescape(arr[2]); return null;}function getcookies(){
document.form1.UserName.value=getCookies(Loginusername);
把你要表单初始化放在这}function delCookies(name){ var exp = new
Date(); exp.setTime(exp.getTime() – 1); var cval=getCookie(name);

复制代码 代码如下:

//JS操作cookies方法!
//写cookies
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();
}
//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();
}
//使用示例
setCookie(“name”,”hayden”);
alert(getCookie(“name”));
//如果需要设定自定义过期时间
//那么把上面的setCookie 函数换成下面两个函数就ok;
//程序代码
function setCookie2(name,value,time){
var strsec = getsec(time);
var exp = new Date();
exp.setTime(exp.getTime() + strsec*1);
document.cookie = name + “=”+ escape (value) + “;expires=” +
exp.toGMTString();
}
function getsec(str){
alert(str);
var str1=str.substring(1,str.length)*1;
var str2=str.substring(0,1);
if (str2==”s”){
return str1*1000;
}else if (str2==”h”){
return str1*60*60*1000;
}else if (str2==”d”){
return str1*24*60*60*1000;
}
}
//这是有设定过期时间的使用示例:
//s20是代表20秒
//h是指小时,如12小时则是:h12
//d是天数,30天则:d30
//暂时只写了这三种
setCookie2(“name2″,”hayden2″,”s20”);
alert(getCookie(“name2”));
