Question

Read a cookie using javascript that has been set by a ASP script

Asked by: logicmedia

Hi there,

This is probaly a simple question, but javascript and cookies is not what I have been using the most so far.

I have a cookie which has been set by the ASP code below.

How do I retrieve the username and domain values fra client side javascript code on a different page?

Thanks in advance

Thomas

Hi there,

it works! Thanks.

I ended up with at modified script that can extract a parameter as well.

The second parameter is optinal

function getCookie(c_name, c_par)
{
  if (document.cookie.length>0)
  {
    c_start=document.cookie.indexOf(c_name + "=");
    if (c_start!=-1)
    { 
      c_start=c_start + c_name.length+1 ;
      c_end=document.cookie.indexOf(";",c_start);
      if (c_end==-1) c_end=document.cookie.length
 
			if (typeof(c_par) != "undefined") {
		  	return getPar(c_par, unescape(document.cookie.substring(c_start,c_end)));
		  } else {
			  return unescape(document.cookie.substring(c_start,c_end));
			}
    } 
  }
  return ""
}
