I need assistance with auto-formatting the postal code entered by the user. The rule for the postal code is to use the format A0A 0A0 or 12345. If the user inputs a code like L9V0C7, it should automatically reformat to L9V 0C7. However, if the postal code consists only of digits, such as 12345, it should remain unchanged. The maximum length should be 6 characters when the code includes both numbers and letters, and 5 characters when it contains only numbers. Can you help me troubleshoot this handlePostalCode method?
The problem I am encountering is that when I input L9V0, the '0' disappears and I am unable to continue entering the postal code.

handlePostalCode() {
if (this.postal_code.match(/^[0-9]+$/) != null) {
var replacedInput = this.postal_code.replace(/\D/g, '').match(/(\d{0,3})(\d{0,2})/);
this.postal_code = !replacedInput[2] ? replacedInput[1] : replacedInput[1] + '' + replacedInput[2];
}
else {
var replacedInput = this.postal_code.match(/(\w{0,3})(\w{0,3})/);
console.log(replacedInput)
this.postal_code = !replacedInput[2] ? replacedInput[1] : replacedInput[1] + ' ' + replacedInput[2];
}
}
