Hi,

Are you opening a link or html file? If the link, is the link on the same domain?

HI,

I test my program and linked page in my localhost (127.0.0.1 Apache on Windows) Both Program (.dll) and Page are in the root of localhost.

Can you try this?

procedure TMainForm.UniButton1Click(Sender: TObject);
begin
  UniURLFrame1.JSInterface.JSCode(#1'.iframe.contentWindow.yourFunction();');
end;

Thank you very much, the code work fine.

I wonder where can I find the document or example of the JSInterface  like this, so I can study them myself, thank you.

@Sherzod, can you do the same for a UniHTMLFrame?

When I do this:

UniHTMLFrame1.JSInterface.JSCode(#1'.iframe.contentWindow.nextStep();');

I get the following error:

Never mind, I figured it out, one can call the function directly for a UniHTMLFrame since it isn't in a iFrame.

This worked:

UniHTMLFrame1.JSInterface.JSCode('nextStep();');
