Google Script not splitting array at comma

Question

var String = "One,Three,Eight";

var temp = String.split(",");

var test = (temp[1][0]);

Browser.msgBox(''+test+'', Browser.Buttons.OK_CANCEL);

I've searched high and wide for why this won't return:

"One" as (temp[0][0])

"Three" as (temp[1][0])

"Eight" as (temp[2][0])

They are only returning O, T and E respectively in the message box. I want each word to be its own array index, is it something to do with a limit?

Thanks

Answer 1

You can test the code by using Logger.log().

function sandbox() {
  var String = "One,Three,Eight";
  var temp = String.split(",");
  Logger.log(temp);
}

This will show you the following value for temp: [One, Three, Eight]

If you log the elements of the array:

temp[0] = 'One'

temp[1] = 'Three'

temp[2] = 'Eight'

If you use temp[1][0] you get the first letter from 'Three'.
