Pass a parameter from page to controller without apex:param in visualforce

Question

The function apex:param only works if there is rerender attribute present with action-function, but I don't want to use rerender as because I have used apex:inputfile on the page, which is causing an error, if there is a rerender attribute. Can suggestions how I can able to do that?

Answer 1

If you don't want to use apex:param then you should use JavaScript Remoting to pass parameters from VisualForce to Apex. Also, you can use apex:actionRegion tag.

I hope this will help.
