How to store a class in a cookie and retrieve?

[yootaeho]

Hi,
I have the following script
<%@LANGUAGE=Javascript%>
<%
var myClass = new LoginInfo();
myClass.sessionID = "1321312131";

Response.Cookies("testingCookies") = myClass;

var recievedCookies = new LoginInfo();
recievedCookies = LoginInfo(Response.Cookies("testingCookies"));

Response.Write(recievedCookies.sessionID);
Response.End();

function LoginInfo()
{var sessionID;}
%>

How to make it work?

Cheers

You need to enable your object to serialise and deserialise the state of the
object to a string.

For example (by no means a complete implementation and is air code). :-

function LoginInfo(vsStateIn)
{
var moState = vsStateIn ? eval(vsStateIn) : {}
vsStateIn = null

this.getSessionID = function() { return moState.sessionID; }
this.putSessionID = function(value) { moState.sessionID = value; }

this.serialise = function()
{
var sState = '{'
for (var key in moState)
{
if (sState.length > 1) sState += ', '
if (typeof(moState[key]) == 'string')
sState += key + ": '" + moState[key].replace(/([\\|\'])/g,
'\\$1') + "'"
else
sState += key + ": " + moState[key].toString()
}
sState += '}'
return sState
}
}


To store the object:-

var oLogin = new LoginInfo()
oLogin.putSessionID("1321312131")

Response.Cookies("testingCookies") = oLogin.serialise() ;


To retrieve the object:-

var oLogin = new LoginInfo(Request.Cookies("testingCookies").Item)
if (oLogin.getSessionID == "1321312131")
{

//is logged on

}
