Question

WebBrowser checkbox value changed, but submit gets wrong status

Asked by: Povilas

var i, j : Integer; FormItem : Variant;
begin
 Result := false;
 if (WebBrowser.OleObject.Document.all.tags('FORM').length = 0) then exit; //no form on document
 for i := 0 to WebBrowser.OleObject.Document.forms.Length - 1 do
  begin
   FormItem := WebBrowser.OleObject.Document.forms.Item(i);
   for j := 0 to FormItem.Length - 1 do
    begin
     try if (FormItem.Item(j).name = fieldname) then
      begin
       FormItem.Item(j).Value := somevalue;
       if somevalue = 'TRUE' then
        begin
/////////////  Can I enable disabled checkbox?
         FormItem.Item(j).enabled := true;
/////////////  The status is actually changed for checkbox, before I submit a form
         FormItem.Item(j).checked := true;
        end;
       Result := true;
      end;  except exit; end;  end;  end; end;

The problem is that webpage changes CHECKBOX value to checked, but when I do submit it reads as the value is unchecked. Then I click back and submit again. Now everything works. Other fields as textbox on submit works fine.
by the way, can I change status (enabled/disabled) of checkbox?

yes you can.
what would be interesting to see is if there is some script (javascript?) present that is executed at submit and which might temper with that checkbox.
is there? if so, does it?

///////// I've changed my function a little bit and it worked (looks like) ////////
if somevalue = 'TRUE' then
 begin
  // FormItem.Item(j).enabled := true;
  FormItem.Item(j).checked := true;
end
else FormItem.Item(j).Value := 'new value';

It looks like when you set a value for CHECKBOX and then mark it as checked, the form gets something incorrect. When I change only status checked, it works. (no idea why setting parameter value is harmful).

ciuly, There are some scripts, but as long as I can change the status of checkbox to checked (even on disabled one), and as log as the form submits everything as checked, I don't mind :-)
