通過JAVASCRIPT讀取ASP設定的COOKIE_javascript技巧

<%
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) {

    return "";

document.write("讀取名稱為 ab 的 cookie..." + RequestCookies("Cookie1").get("key1"));
