Arcade syntax question: checking if value is in a list

Katie_Clark

Hello,

I am hoping this is a fairly simple question but I'm just a bit unclear on the syntax for Arcade and haven't been able to find the answer I need.

I want to return a certain value based on whether the county name is in a predefined list or not.

Something like this:

var counties = ['County1', 'County2']
if ( $feature.NAME IN counties ) {
return "Processed"
}
else {
return "Not Processed"
}<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Thanks in advance for any guidance!

Cheers,

KC

Not sure if this is the offical way of doing this but if you use indexOf(list, value) and the value isn't in the list it returns a -1, so you can set up a little switch using it! See below:

<SPAN class="keyword token">var</SPAN> counties <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN><SPAN class="string token">'County1'</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'County2'</SPAN><SPAN class="punctuation token">]</SPAN>

<SPAN class="token function">IIF</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="token function">indexOf</SPAN><SPAN class="punctuation token">(</SPAN>counties<SPAN class="punctuation token">,</SPAN> $feature<SPAN class="punctuation token">.</SPAN>NAME<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="string token">"Processed"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"Not Processed"</SPAN><SPAN class="punctuation token">)</SPAN>‍‍‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
