My first EWB app works perfectly after just a few hours, Kudos for a brilliant system for Delphi developers.

But I would like to pass a parameter to my EWB app from another web page that calls it.  How do I get parameters from the calling URL?

My guess was that someone mentioned windows.location, but I get errors when I try to reference it, how do I reference a global variable like Window?  

Or maybe something like ParamStr(), but that didn't seem to work either.

Thanks in advance.

My attempt so far gets me the data, but also an error:
I added webdom to the uses clause
then
showmessage( window.location.search );
which gives the correct parameter string, but then gives the error:
 Error executing request: access to restricted URI denied

I forget the exact line but it is something like window.something.search

It has been discussed here before, and is a standard browser thing. Google
or the EWB source will lead you to the proper items.

I see you got it. Just assign it to a string. I've not had trouble with it
as you describe.

Seems to work fine here  - is your code trying to access anythign else
(to cause the error) ?

Or what exactly are you passing in as param(s) ?


Something like this works fine here without any errors:

procedure TForm1.Form1Create(Sender: TObject);
begin
   MultiLineEdit1.Lines.add(window.location.search);
end;

and shows the expected URL param string in edit window.

::Seems to work fine here  - is your code trying to access anythign else

Yes, that works fine now.  Just as it should.
