Hi All,

In my web application, I'm creating some cookie using VBScript and later I'm reading those cookie using JavaScript.

The problem is whenever there space in cookie value, the space is getting converted to "+" when I read the same cookie in javascript code.

For example in the below code the "LastName MiddleName FirstName" cookie value is getting printed as "LastName+MiddleName+FirstName" when I read the cookie value using JavaScript.

How can I avoid this ? Please note that  unescape(document.cookie) and document.cookie returns the same value in the current example

Thanks,
Lilupat

<%@ Language=vbScript%>
<%
     'create a cookie in VBScript
     Response.Cookies("name") = "LastName MiddleName FirstName"
     Response.Cookies("name").Path = "/"
      
Response.Write("In VBScript Cookie Value: " & Request.Cookies("name"))

%>

<html>
<head>
<script language="javascript">
   alert("In JavaScript Cookie Value:" + unescape(document.cookie));
</script>
</head>
</html>

lilupat,
Why don't you just use Replace() function to eliminate the extra "+" sign?
Eg:
VBScript
----------
<%
..
Response.Write("In VBScript Cookie Value: " & Replace(Request.Cookies("name"),"+"," ")
%>

Javascript
-----------
<script language="javascript">
   alert("In JavaScript Cookie Value:" + (document.cookie).replace('+',' ');
</script>

lilupat,
Then, you need to use escape() before store any value into the cookies. When you need to retrieve, you can use unescape(). This sure be work for you.

Hi x_com,

That won't help me either.

As I know we should not escape the cookie value when we create a cookie in VBScript because ASP(script) automatically takes care escaping the same. One more thing if I escape the value in VBScript, how I will unescape the same in Javascript.

For example if I create a cookie value in VBScript like
Response.Cookies("test") = escape("What is your FirstName?")

Then if I read the same in JavaScript, the value I get after unescape the cookie value is "what%20is%20your%20FirstName%3F"

lilupat,

If you want to store the value for lastname, middlename, firstname,
why don't you just store the value into this way in cookies?
Eg:

Response.Cookies("user")("lastName") = "LastName"
Response.Cookies("user")("middleName") = "MiddleName"
Response.Cookies("user")("firstName") = "FirstName"

lilupat ,
>>VBScript
-You need to do like this :
<%
 'vbscript
 Response.Cookies("user")=escape("lastname middlename firstname")
 Response.Write(unescape(Request.Cookies("user")))  
%>

if you set cookies use vbscript, when you retrieve the cookies value in jscript, you need to replace() the cookies with "%" to " "
or

if you set cookies use jscript, when you retrieve the cookies value in vbcript, you need to replace() the cookies with "+" to " "

But, my best advice is you try to store the value into an array in single cookies, like this :
<%
Response.Cookies("user")("lastName") = "LastName"
Response.Cookies("user")("middleName") = "MiddleName"
Response.Cookies("user")("firstName") = "FirstName"
%>

-this method sure be work for vbscript and jscript without doing any extra job for escape() or unescape().

I got an idea, instead of creating the cookie in VBscript, I can set the same in Javascript inside the ASP page, like

Response.write("<script language='Javascript'>")
Response.write("document.cookie ='cookie_name=" & cookie_value & "'")
Response.write("</script>")

I think this will solve my problem.

Thanks x_com for replying to my query.
