Passing Variable to Javascript

[Wajeed]

Newbie to unigui and javascript,

I am trying to pass variable from a unigui form to javascript.I tried two methods as discussed in forum

First method

on Mainform.oncreate
 Self.WebForm.JSInterface.JSAssign('myvar', [2356]);

on same form button1 clientevents(ExtEvents) , I tried to access the variable

function click(sender, e, eOpts)
{
  var n1 = MainForm.windows.myvar;
  alert(n1);
}

nothing happens.

-----------------

Second method
on Mainform button click

procedure TMainForm.UniButton2Click(Sender: TObject);
begin
UniApplication.UniSession.AddJS('var myVar = 1');
end;

clientside(Extevents)
function click(sender, e, eOpts)
{
  var n1 = uniVars.myVar ;
  alert(n1);
}

i get undefined alert message at runtime when i click the button.

Correct - var n1 = MainForm.window.myvar;
