Lze v popisku v ArcGIS Online použít příkaz If Then Else?

durshe

Snažím se přidat do vrstvy v AGOLu následující výraz, ale nedaří se mi ho zprovoznit...

Takhle to mám nastavené v ArcGIS Desktopu a funguje to...

Function FindLabel ( [InspectionOrigin], [ClockFromTrans], [ClockFrom] )

if ( [InspectionOrigin] <> "D") then
FindLabel = ( [ClockFromTrans] )

elseif ( [InspectionOrigin] <> "U") then

FindLabel = [ClockFrom]
end if

End Function

Snažím se to zopakovat v AGOLu pro jednu ze svých vrstev, ale nedaří se mi to zprovoznit.

Vyzkoušel jsem několik možností, ale žádná zřejmě nefunguje.

Možnost 1

IIf($feature.InspectionOrigin = Text($feature.InspectionOrigin, 'U'), $feature["ClockFromTrans"], $feature["ClockFrom"])

Možnost 2

IIf($feature.InspectionOrigin = 'U'), $feature["ClockFromTrans"], $feature["ClockFrom"])

Možnost 3

IIf($feature.InspectionOrigin <> 'D'), $feature["ClockFromTrans"], $feature["ClockFrom"])

Napadá někoho, čím by to mohlo být?

Díky!

There are a couple way of doing this. First would be to use an If statement

if ( $feature.InspectionOrigin != "D") {
  $feature.ClockFromTrans
}
else if ( $feature.InspectionOrigin != "U") {
  $feature.ClockFrom
}‍‍‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

You can also use the logical function IIF

iif <SPAN class="punctuation token">(</SPAN>$feature<SPAN class="punctuation token">.</SPAN>InspectionOrigin <SPAN class="operator token">!=</SPAN> <SPAN class="string token">"D"</SPAN><SPAN class="punctuation token">,</SPAN> $feature<SPAN class="punctuation token">.</SPAN>ClockFromTrans<SPAN class="punctuation token">,</SPAN> $feature<SPAN class="punctuation token">.</SPAN>ClockFrom<SPAN class="punctuation token">)</SPAN>‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>
