Data validation is more and more important for web browser form submission.JsJava offers many validators for data validation,with which you can validate number,url,email,date,scale and so on.

The libraray for validation is jsorg.eob.validator.Except for common validators such as BooleanValidator,EmailValidator,IP4Validator,JsJava offers localization validators according to language.Take china for example.In jsorb. eob.validator.language.zh,JsJava offers localization validators such as OicqValidator, ZipValidator,IDCardValidator and so on.

How to use these validators? We take some examples:

e.g.1 NumberScaleValidator <script src="jsjava-2.0.js"></script> <script> document.write(NumberScaleValidator.validateBetween(35,34,36)+"<br>"); document.write(NumberScaleValidator.validateLargerThan(35,50)); </script> e.g.2 IP4Validator <script src="jsjava-2.0.js"></script> <script> document.write(IP4Validator.validate("300.16.4.176")+"<br>"); document.write(IP4Validator.validate("192.16.4.176")+"<br>"); </script> e.g.3 IDCardValidator <script src="jsjava-2.0.js"></script> <script> document.write(IDCardValidator.validate("13182919600375221x")+"<br>"); document.write(IDCardValidator.validate("131829196003752215")+"<br>"); document.write(IDCardValidator.validate("1318291960037522157")+"<br>"); </script>
