google app script: on form response, check which tab of the sheet collects the responses

Question

I am trying to automate some extra data generated to a form response using Google App Script; (in particular, a unique identifier). I can trigger a script on a form response, but I have multiple forms connected to this sheet document, so I need to make sure that the correct form is triggering the response, and then I would like to write the values to the correct sheet of the document.

How do I check which form is being triggered, and how can I find the sheet that collects it's responses?

Answer 1

I assume you've already set up the function on the sheet to capture the "on submit" event. You can get the [sheet] object from the e (event) argument.

//make sure to set up the form submit trigger from
//your script menu: Edit -> Current Project's Triggers

function onSubmit(e) {
   var range = e.range
   var sheet = range.getSheet();

   //then do something with [sheet] object

}

I'm pretty sure you can only connect one form to a sheet, so knowing which sheet got written to will tell you which form was submitted.

Check out more about event triggers in the documentation.
