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

Anonymous User

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

<SPAN class="keyword token">if</SPAN> <SPAN class="punctuation token">(</SPAN><SPAN class="token function">IndexOf</SPAN><SPAN class="punctuation token">(</SPAN>myList<SPAN class="punctuation token">,</SPAN> feature<SPAN class="punctuation token">.</SPAN>$Number<SPAN class="punctuation token">)</SPAN> <SPAN class="operator token">></SPAN> <SPAN class="operator token">-</SPAN><SPAN class="number token">1</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">{</SPAN>
  <SPAN class="keyword token">return</SPAN> <SPAN class="string token">"Matched"</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="punctuation token">}</SPAN> <SPAN class="keyword token">else</SPAN> <SPAN class="punctuation token">{</SPAN>
  <SPAN class="keyword token">return</SPAN> <SPAN class="string token">"No Match"</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="punctuation token">}</SPAN>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
