How to Fill in Google Form Using Javascript

[Ganee]

I have a field Day in Google Form.

I would like to use this JavaScript 

var arrayOfWeekdays = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]

var dateObj = new Date()

var weekdayNumber = dateObj.getDay()

var weekdayName = arrayOfWeekdays[weekdayNumber]

This entire code doesn't work in the variable tab. I tried putting this into the JavaScript field tab, but I can't get the input field name in Google Form. Any help?

What type of field is Day? (e.g., dropdown, text)

Can you provide link to this form?

It's a text field.

The form is -  https://docs.google.com/forms/d/e/1FAIpQLSc4C8J09Vq1NgfzglyQNVDLFSP52Vlupx9ajmGV3AGn2xZcow/viewform?fbzx=714933301789700178

The field name is "HARI". It's the name of the day. So basically, I am trying to get today's date and get the name of the day.

You have uncovered a bug in Autofill where you cannot have a space before or after "=" in your JS code. This will be fixed in the next release. In the meantime, this will work -- enter in Variables tab:

day = javascript:let aDays=['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']; aDays[(new Date()).getDay()]

Thanks a lot! It works beautifully. 

I would like to find out if the variable section only allows a single line of JavaScript? I can't create multiple lines of function in there?

[Autofill Chrome Extension]

That is correct, variable assignment is limited to one line per variable (treat a variable like a bookmarklet).

This bug has been fixed in v10.
