Incrementing an Alphabetic Field

[Former Community Member]

Is there a way to increment a letter field? That is, on a specific event, change the field to "B" if it is now "A"; change to "C" if it is now "B", etc.

In JavaScript:



var char = TextField1.rawValue + "";

var asciiCode = char.charCodeAt(0);

var lastChar = "Z"; // Don't let them go past Z



if (asciiCode < lastChar.charCodeAt(0)) {

var nextCode = asciiCode + 1;

TextField1.rawValue = String.fromCharCode(nextCode);

} else {

// Throw error or ignore?

}

Thanks,

Seems to work as desired.
