Is there a custom validation script for a Canadian Postal Code (form was created in Acrobat XI)? Thanks much.

I spent hours trying to find the perfect script that worked exactly as I wanted. I wanted to be able to enter it a1a1a1, A1A1A1 or a1a 1a1 and they all auto correct to A1A 1A1. This was a far bigger struggle than it should have been, ChatGPT and I had quite the morning. Anyway, I'm pasting my script here in case anyone else is struggling.

event.value = event.value.toUpperCase(); // Convert to uppercase

// If the field is empty, allow it without any further validation
if (event.value === "") {
event.rc = true;
} else {
// Automatically insert space after the third character if missing
if (event.value.length === 6) {
event.value = event.value.substring(0, 3) + " " + event.value.substring(3);
}

// Validate against the Canadian postal code format (excludes invalid letters: D, F, I, O, Q, U)
var pattern = /^(?!.*[DFIOQU])[A-VXY][0-9][A-Z] [0-9][A-Z][0-9]$/;

if (!pattern.test(event.value)) {
app.alert("Please enter a valid Canadian postal code (Format: A1A 1A1)", 3);
this.resetForm([event.target.name]); // Clears the field if invalid
}
}

Okay, I finally got it to work. I had to remove "comb 6 characters" under the Appearance tab. The Postal Code fields in this form have separate slots for each character -- this is essentially for users who prefer to print and complete the form by hand. Unfortunately the Postal Code JavaScript won't work with a "comb of characters"; so I set the alignment to "center" instead. It looks a little awkward -- but it works. Attached is a screenshot.

Thanks, gkaiseril.

It should work. the length is not 6 but 7 since a space is a character.

One possible solution that includes validation for the Postal District, the Forward Station Area, and the Local Delivery Area:

event.value = event.value.toUpperCase();

if(event.value != "")

{

// validate Canadian postal code;

event.rc = /^(?!.*[DFIOQU])[A-VXY][0-9][A-Z] [0-9][A-Z][0-9]$/.test(event.value);

if(event.rc == false)

{

app.alert("Please enter a correct Canadian Postal code", 1, 0);

this.resetForm([event.target.name]);

}

Note there are only 18 valid Postal Districts. The negative look ahead eliminates the 6 alphabetical characters form anywhere in the string.

See Postal Codes in Canada for more information about the structure of the Canadian Postal Code.

The form field is reset incase a previous correct Postal Code is replaced with an invalid code and the correct Postal Code is not retained as the value of the field.

Hi gkaiseril,

Thanks very much for your reply. I don't know JavaScript - but it doesn't seem to matter what postal code I enter, I get an error message; and the letters don't appear in uppercase.
