<%
Response.Cookies("Cookie1")("key1") = "KeyValue2"
%>

<script language="javascript">

String.prototype.get   =   function(name){
var   reg = new RegExp("(^|&|//?)" + name + "=([^&]*)(&|$)"),r;
if(r=this.match(reg))
return unescape(r[2]);
return null;
}

//获取并返回 cookie 值
//不区分 cookieName 的大小写
//dfltValue 为默认返回值
//不考虑子键
function RequestCookies(cookieName)
{
    var lowerCookieName = cookieName.toLowerCase();
    var cookieStr = document.cookie;

    if (cookieStr == "")return "";


    var cookieArr = cookieStr.split("; ");
    var pos = -1;
    for (var i=0; i<cookieArr.length; i++){
        pos = cookieArr[i].indexOf("=");
        if (pos > 0) {
            if (cookieArr[i].substring(0, pos).toLowerCase() == lowerCookieName)
            {
                return unescape(cookieArr[i].substring(pos+1, cookieArr[i].length));
            }
        }
    }

    return "";
}

document.write("读取名称为 ab 的 cookie..." + RequestCookies("Cookie1").get("key1"));
