getCorrectlyPaddedNumber: function(number) { number = String(number); if(gs.nil(number)) return number; var grNumber = new GlideRecord("sys_number"); grNumber.addQuery("category", "=", "kb_knowledge"); grNumber.query(); if (grNumber.next()) { this.PREFIX = grNumber.prefix + ''; this.DIGITS = grNumber.maximum_digits; } if (number.length == (this.DIGITS + this.PREFIX.length)) return number; number = number.replace(this.PREFIX, ''); //Remove prefix number = number.replace(/^0+/, ''); // Remove leading zeros number = number.padStart(this.DIGITS, '0'); // Pad with zeros to meet the required length return this.PREFIX + number; //Add the prefix back }, 3. Save the script include.
