[Javascript] Getting info. from URL of a page that is in frames

[javascript@xxxxxxxxxx (Steve Hearne)]

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=20
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'.
