Check for blank input in api

kirby-jewett

I am writing an new api transaction and have an input field defined as 1 numeric (Type=N, Length=1).
The input value is used to update a field in a table but only if the user has entered a value (valid values are 0 to 4) -- in other words, if the user enters a blank (space) or nothing at all (null), the table field will not be updated.

I have control of the null value:
if (mi.in.get("PDCC") == null) updateField = false

But I'm having trouble catching the blank value.
I have tried the following but it didn't work.
String s = mi.inData.get("PDCC") == null ? "" : mi.inData.get("PDCC").trim()
if (s == "") updateField = false

Does anybody have a suggestion?

Hi Kirby, I prefer to keep it null.

iPDCC = mi.inData.get("PDCC")

Then condition if statements later e.g.

if (iPDCC != null) {

}

You could also do the following to detect if a value has been provided and set iPDCC as a global variable set to 0.

if (mi.inData.get("PDCC").toString()?.trim()?.size() > 0) {

iPDCC = mi.inData.get("PDCC").toInteger()

}
