Google表单/ Google表格的JavaScript验证

Question

It's been a while since I've done JavaScript, but I could just be having issues with Google Scripts...

I'm trying to validate a response to a Google Form. Essentially, we send out a form asking for a name, email and code word given at the end of a webinar. If the user responds correctly, we want to send them an email with a URL to a form with ethics credit. If incorrect, we want to send them an email with their incorrect response. Currently, I can pull all the data, but for some reason, cannot change valid to false...So far, I know that everything before "var valid = false" works. Can someone tell me what I'm doing wrong here? Thanks.

/* before this section - gets values from separate Google sheet
   and gets other responses from the Google Form */

var submission = itemResponses[2].getResponse(); // gets code word response from form

var newSubmission = submission.toLowerCase().trim(); // format submission;

var valid = false;
var month = "";
var url = "";


for(var i; i < range.length; i++) {
   if(range[i][1] == newSubmission) { // range is the range in the spreadsheet. 
                                      // [i][1] is the second col of selection.
     valid = !valid;
     month += range[i][0];
     url += range[i][2];
     break;
   }
}

After this, it just sends the email. I do receive emails, but they always come as the false response...

Answer 1

如果要让循环开始更改此行，则必须将值设置为i：for（var i; i <range.length; i ++）{by for（var i = 0; i <range.length; i ++）{

Yeah, sorry, I forgot to take this down. You were correct, ClemT. Here's the full code, if anyone would like to view it.
