[Javascript] Half-baked cookies

[javascript@xxxxxxxxxx (Steve Hearne)]

Okay - i admit it, i'm cheating.  My JavaScript is a bit poor....Could you =
please, please, please give me a bit of code?

I know that immediately previous to the item i want to grab in the string =
is the value ;

....<ESC?>usrsvr<ESC?>

After this is the username of the peson who is logged into the machine =
(this cookie is made by portal software - and this seems to be the only =
way which i can retrieve the users name).  So, i imagine that i need the =
following code;

for j=3D1 to len of the cookie string
   if mid(cookiestring,j,6)=3D"usrsvr" then
     username=3Dmid(cookiestring,j+7,10) // this assumes that the username =
is 10 chars long, i can cut it out better later on
  end if
next j

But i'm really not sure how to do this in JavaScript.

Please help if you can,
Steve

    Can you suck in one of those unknown values by grabbing one that has a
known position in the string?  Then you could just walk your way through =
the
string based on the wacky delimiters (which I think was your objective
anyway).

Phew.  I wouldn't have thought cookies could be so haaaaaard! Please help =
me
as i am struggling.

I would like to read the 20th item in a cookie when a user hits the page
which generates that cookie.

The items appear to be separated with ''ESC' characters (they appear as
black squares in Notepad) but I am not to sure.

Any help gratefully received.
Thanks,
Steve

Thanks for the help so far.  I've just realised that, because my page is
split into 3 frames, i'm not sure which of these frames will have access =
to
the URL - if any?

Sure

var x =3D location.search;
var y =3Dnew Array();
y =3D x.split('&');

Now the array y contains the name/value pairs of the query string. To find
the user name, do

for (i=3D0;i<y.length;i++)
{
  if (y[i].indexOf('user') =3D=3D 0)
  {
    var z =3D new Array();
    z =3D y[i].split('=3D');
   username =3D z[1];
  }
}

and the username is in variable 'username'.
