cookie的存取
/写cookies 一路径为标准,Path – 路径
function setCookie(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() + ";path=/";
}
//设定cookies过期时间
function getsec(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;
}
else if (str2 == "m") {
return str1 * 30 * 24 * 60 * 60 * 1000;
}
}
//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() + ";path=/";
}
