Almost any web application we develop has a bit of JavaScript validations that we code into it. But it would really be a re-inventing of the same wheel putting the same logic over and over again. Also, it brings along with it, the difficulties of maintaining multiple code sets, consistency and a lot of problems. I was searching for some JavaScript validations and came across a JavaScript Validation library called fValidate which we can download for free from http://www.peterbailey.net/fValidate/
The Validation Library is very customizable and you can also precisely say how do you want the error messages to be displayed like Scripting Alert Popup, inline DHTML Message (similar to ASP.NET RequiredFieldValidator and ValidationSummary for Microsoft Internet Explorer and uplevel browsers) etc.
Since this library is also a freeware downloadable and quite easy to configure, I hope it would be very useful for development fraternity of web-based applications worldwide.
