How can I write this Code Block as an Arcade expression
You are missing a couple of curly brackets. Each return statement needs to be enclosed by curly brackets. Also, you need to use a double equals sign when checking if something is equal to a value. A single equals sign is used for assigning variables.
if($feature.MAJOR_ST == 'Farm'){ return "No" } else { return "Yes" }
Refer to If - else | ArcGIS Arcade | ArcGIS Developers for info on if-else syntax.
Refer to Operators | ArcGIS Arcade | ArcGIS Developers for operators, which discusses = vs ==.
For straight forward if-else statements, arcade also has an IIF function, which can be a little easier to create:
IIF($feature.MAJOR_ST == "Farm", "No", "Yes")
Logical functions | ArcGIS Arcade | ArcGIS Developers
That worked!
Thank you so much!
Hi,
I tried looking for a solution in the link you provided but wasn't successful. What I am trying to do is write a simple Arcade expression to find all streets in my map with a Street type of Farm and return a value of "No" but if Street type is not = to Farm then return a value of "Yes".
This is all I can come up with but it doesn't verify
Can you help me with this?
I know just enough coding to stumble my way through an expression in VB. I have never used Arcade. I will try your link and see if I can find something. Thanks
https://developers.arcgis.com/arcade/ has all kinds of resources. Your question isn't very specific, though. Is there a particular part you're having trouble with?
Arcade follows many of the conventions of JavaScript, so familiarity with that will help.
// defining a function function myExpression(some_param) { // do something here return 'some value' } // an if-else block If (some_condition) { // do something } else if (another condition) { // do something else } else { // do this if nothing else worked }
