Sumit button value cannot be fetched

Question

I have a aui-form with a two submit buttons. For each button I have a if condition. I tried getting the button value but its returning null(checked in debug mode). Can anyone explain me why is this happening and what's the solution?

Answer 1

(This is all just educated guessing as you didn't provide much information - see the comment of Parkash Kumar)

If you have placed your submit button in an if tag (taglib), the button might not be there due to the if statement, hence returning null when you try to access it via JavaScript.
