Enter on X or N/A in a text field

Then I would write a document JavaScript level function for the custom keystroke or validation and call that function or functions in the custom keystroke or validation as needed.

I would use the following Custom KeyStroke script  to convert each key entered to upper case:

if(!event.willCommit)

{

event.change = event.change.toUpperCase();

}

I would create a document level function that verifies a string is either an empty string, an "X", or "N/A". It returns logical true value if either of those conditions is met. This returned value can be used to set the return code for a validation script.

function XNA(cString)

{

var RC = true;

cString = cString.toUpperCase();

if(cString != "X" && cString != "N/A" && cString != "")

{

  app.alert("Enter 'X' or 'N/A'", 1, 0);

  RC = false;

}

return RC;

} // end function XNA which tests a String for being X, N/A or a null string;

I can then have a validation script like:

event.rc = XNA(event.value);
