How to combine an IF statement inside a for loop in Arcade ?

Anonymous User — Tue, 30 Jun 2020 20:29:02 GMT

Hello,

I have an array of numbers (around 800 numbers) var mylist = [604703,607006,607606,607607,.................]

and I have a Number datatype field in one of my layers. I want to see if the data inside this field match any of the numbers in mylist? and when it does it will say for example " Matched " if does not " No Match".

Thank you.

You can use IndexOf to determine whether an item is found in array

if (IndexOf(myList, feature.$Number) > -1){
  return "Matched";
} else {
  return "No Match";
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Not that this is any better than Ken's answer, just a slightly different code structure:

IIf(IndexOf(myList,feature.$Number) > -1, "Matched", "No Match");‍
