ShowMask - JS Code

[herculanojs]

Hello friends. Necesito call showmask via JS code in situations which do not own visual component that will trigger by a user click.

 

Does anyone know tell me how could run it.

I use this simple approach for custom events    In JS code

MainForm.form.showMask('Loading...');
ajaxRequest(...);

In ajax event

try
  ...
finally
  UniSession.AddJS('MainForm.form.hideMask();');
end;

Actually you don't need to call hideMask()

fine, tanks brothers

On a 2nd thought. If object sending the ajaxRequest is different from object which is displaying the mask then you need to call hidemask().
