通過JAVASCRIPT讀取ASP設定的COOKIE

複製代碼 代碼如下:<%
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;
}

//擷取並返回 cookie 值
//不區分 cookieName 的大小寫
//dfltValue 為預設傳回值
//不考慮子鍵
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("讀取名稱為 ab 的 cookie..." + RequestCookies("Cookie1").get("key1"));
-->
</script>
