I had the need for a URL Validator for a Flex project, and couldn’t find one. So, here’s the code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | package org.iotashan.validators { import mx.validators.ValidationResult; import mx.validators.Validator; public class URLValidator extends Validator { public function URLValidator() { super(); } override protected function doValidation(value:Object):Array { // Clear results Array. var results:Array = []; // Call base class doValidation(). results = super.doValidation(value); // Return if there are errors. if (results.length > 0) return results; // match regex pattern var pattern:RegExp = new RegExp("^http[s]?\:\\/\\/([^\\/]+)\\/"); // run the pattern, but don't error if there is no value and this is not required if (!(!required && !value) && !pattern.exec(String(value))) { results.push(new ValidationResult(true, null, "notURL", "You must enter a valid URL.")); return results; } return results; } } } |
