pre-fill google form from google apps script

问题

I have a student registration form, there's student id which is a required field. I have a google apps script function which tells if this student is registered for any class or not. Is there a way to auto-fill the field course registered via calling the google apps script function yes or no.

Yes you can create a pre filled response with the forms ID, not that the pre filled fields are showed in the URL

Function formPrefill(formId){
    var form = FormApp.openById(formId);
    try{
    var items = form.getItems();
    var formResponse = form.createResponse();
    // Prefill SessionId
    var formItem = "SOMETHING HERE"
    var response = formItem.createResponse(sessionId);
    formResponse.withItemResponse(response);

    //--------ANOTHER FIELD-------------
    formItem = items[4].asMultipleChoiceItem();
    response = formItem.createResponse('YOUR FIELD NAME');
    formResponse.withItemResponse(response);

    }catch(e){catch an error here}


}
