Good day honorable adobe forum members,

 

I am looking for the method to use to check if a value is in a list

 

i.e.:

 

var list = ["A","B","C"]

if ("a"  in list) {
//dothings
}

 

Hoe does one do this effectively?

 

Thank you in advance for any and all trouble to be taken

Yes, using the indexOf method. See: https://www.w3schools.com/jsref/jsref_indexof_array.asp

I see I typed "a" instead of "A" , I hope this doesn't cause confusion (the example should say "A")
