JSAssign

[dkeene]

Hello

I am trying to pass variables from the delphi form to unigui Javascript and back. I have successfully created a variable called 'CurrentX' and in the delphi unigui form i execute: 

   Self.WebForm.JSInterface.JSAssign('CurrentX', [123456]); //some arbitrary number.

Then, from a component's ClientEvents (ExtEvents) i can view the variable value via:

   fmMyForm.windows.CurrentX  //value 123456.

I can set this variable to another value from within the ClientEvents (ExtEvents)

  fmMyForm.windows.CurrentX=654321;

 

My Question is: Back on the unigui form, how can I access this value?

Thank you

Doug

One possible solution, simply use with ajaxRequest:

fmMyForm.window.CurrentX=654321;
ajaxRequest(fmMyForm.window, 'setCurrentX', [...]);

Thank you; if there is a Self.WebForm.JSInterface.JSAssign, should there not be an opposite method to retrieve the value?

something like:

Self.WebForm.JSInterface.JSRetrieve('CurrentX', [aVariable]);

No...

The action must be from the client side.
