Question

My question is about the parameter ‘e’ in server side handlers in GAS.

If i have a handler like

function handler(e)
{
}

I want to know what all is accessible using “e.parameter.”
What is e.parameter? Can i get the source widget that raised the handler?

Answer 1

What is e.parameter?

The e.parameter is an instance of the Object class which stores values of widgets which were added to the handlers internals using the ServerHandler.addCallbackElement method.

Can i get the source widget that raised the handler?

Yes, it is possible by defining the widgets ID by calling its setId method and using the parameter.source variable, which contains the caller id, and the UiInstance.getElementById method.
