Google Script: getActiveSheet() when there is no Active Sheet? - google-sheets

Question

I've been working on this for a couple on days, and I can't find any answer to this issue.
I don't have a programmer background, so it might be an easy question for some of you.
The issue:
I have 5 Google Forms that fill 5 different Sheets in 1 Master Google Sheet.
--> When Google Form 1 is filled, there is a new line in sheet1
--> When Google Form 2 is filled, there is a new line in sheet2
--> When Google Form 3 is filled, there is a new line in sheet3
--> When Google Form 4 is filled, there is a new line in sheet4
--> When Google Form 5 is filled, there is a new line in sheet5
Now, I would need to be able to run some script (different ones) when a new line is added to each sheets.
The idea is:
--> When a new line is added to sheet1, do this.
--> When a new line is added to sheet2, do this.

I tried something like this (see below). But it doesn't return anything since there is no "Activesheet" when the google form is filled and add a new row by himself to Google sheet.
function onChange(event) {
var s = event.source.getActiveSheet();
var sName = s.getName();
Browser.msgBox(sName);
}
Question:
In other words, do you have a idea about how I can get the sheet that was edited by the google form, so that I can run specific script for each sheet when it gets modified ?

Answer 1

the onChange trigger does not fire on form submission, use the FormSubmit trigger instead
The related event objects are specified here.
The event object source is not available, but instead you can use the event object range in combination with getSheet().
Sample:
function onChange(event) {
var s = event.range.getSheet();
var sName = s.getName();
Browser.msgBox(sName);
}
