Cookie网页缓存信息

js中：

/** 记录Cookie */
function setCookie(name, value, expireHours) {
    var cookieString = name + "=" + encodeURIComponent(value);
    //判断是否设置过期时间
    if (expireHours > 0) {
        var date = new Date();
        date.setTime(date.getTime() + expireHours * 3600 * 1000);
        cookieString = cookieString + "; expire=" + date.toGMTString();
    }
    document.cookie = cookieString;
}

/** 获取Cookie */
function getCookie(name) {
    var cookies = document.cookie;
    var list = cookies.split("; ");      // 解析出名/值对列表
    for (var i = 0; i < list.length; i++) {
        var arr = list[i].split("=");   // 解析出名和值
        if (arr[0] == name) {
            return decodeURIComponent(arr[1]); // 对cookie值解码
        }
    }
    return "";
}

/** 清除Cookie */
function delCookie(name) {
    setCookie(name, "", 0);
}
