cookie的存取

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=/";

}
