在Google Form应用程序脚本中运行onload函数

Question

I have a Google Form and a script and a script bound to the form. I'm trying to get a function to run when a user fill in the form.

But the only function I get to run is when a hook it to the OnFormSubmit trigger. No other function is running, no matter what I try.

Can I run a function i Google App Script on initial load when a user is filling the form? Is this possible?

Thanks

More details (I'll accept some other way to accomplish the task):

the function should capture some url parameters I pass to the form, and send it over to Google Analytics... I believe that part is solved here: Google Forms & The Measurement Protocol

As the form has several pages, the parameters I pass to the first page gets lost when the user goes to next pages, so I cannot capture them when submitting the form - therefore I'm trying to do it whenever the users first edits the form.

I tried to add the params as prefilled fields on a hidden page, but if it is hidden then it too gets lost on submitting...

Since Sandy did not write out an answer, I will.

You cannot execute Apps Script as part of a form when the user visits it. You can't modify a form as the user is filling it out (Dynamic form...etc). If you need this type of behavior, you will need to create your own form as part of a Apps Script Web App.
