[Javascript] Cookies smell good!

[Steve Hearne]

Yeah!  

That works fine - i put in;

var cookiestring=document.cookie

and i'm on my way to grabbing the portion i want.  Now, I'd like to be able to save this info. so that i can use it later on.  I suppose that i can't save it as a cookie because this document already has a cookie - the one i grabbed the info. from.  So - can i save it, or refer to it from future pages?  Unfortunately, i can't do any ASP stuff yet because this page MUST be HTML - the Portal software dictates this.

Any ideas please?
Thanks again for all the help so far btw.
Steve

Oops.

This script returns the asterisk character (change it to something else and
see).

<SCRIPT LANGUAGE="JavaScript">

// the string to parse
var cookiestring = "|usrsvr*booga|";

// find the beginning of "usrsvr" and then go to the end
var position = cookiestring.indexOf("usrsvr") + "usrsvr".length;

 // use the substr function, feeding it the start position and the desired
length of the result
alert(cookiestring.substr(position,1));

</SCRIPT>

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=1 to len of the cookie string
   if mid(cookiestring,j,6)="usrsvr" then
     username=mid(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 = location.search;
var y =new Array();
y = x.split('&');

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

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

and the username is in variable 'username'.
