Using JavaScript to read the Cookie_javascript techniques set by ASP

Copy Code code as follows:

<%
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;
}


Gets and returns the cookie value
does not differentiate between cookiename and uppercase
Dfltvalue is the default return value
No Child keys considered
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 ("Read cookies with Name ab ..." + requestcookies ("Cookie1"). Get ("Key1");
