用法:
一、设置cookie
var cookie = new JSCookie();
// 普通设置
cookie .SetCookie("key1","val1");
// 过期时间为一年
var expire_time = new Date();
expire_time.setFullYear(expire_time.getFullYear() + 1);
cookie .SetCookie("key2","val2",expire_time);
// 设置域及路径,带过期时间
cookie .SetCookie("key3","val3",expire_time,".cnblogs.com","/");
// 设置带子键的cookie,子键分别是k1,k2,k3
cookie .SetCookie("key4","k1=1&k2=2&k3=3");
二、读取cookie
// 简单获取
cookie .GetCookie("key1");
cookie .GetCookie("key2");
cookie .GetCookie("key3");
cookie .GetCookie("key4");
// 获取key4的子键k1值
cookie .GetChild("key4","k1");
三、删除
cookie .Expire("key1");
cookie .Expire("key2");
cookie .Expire("key3");
cookie .Expire("key4");
示例:
用正则的方法读取cookie值
由于asp的cookie是经过url编码的,所以读之前要unescape一下。
下面是我用正则的方法取cookie,包括单值和多值:
/**************************************************
参数说明:
sMainName Cookie名
sSubName Cookie子键名,留空表示单值Cookie
**************************************************/
function GetCookie(sMainName, sSubName)
{
var re = new RegExp((sSubName ? sMainName + "=(?:.*?&)*?" + sSubName + "=([^&;$]*)" : sMainName + "=([^;$]*)"),"i");
return re.test(unescape(document.cookie)) ? RegExp["$1"] : "";
}
