Regular expression for validating name in javascript local dating in wiltshire

The Len & Mid bits are to stop initials, or people putting in "S J ". And no single person has more than three or four names total?

There is probably a more elegant way of doing this but I'm rather fresh to REGEX. And no doubt the same person will forever be identifiable by the same name?

So how are regular expressions implemented in Java Script? 2) When you need to dynamically construct the regular expression, via the The Reg Exp() method allows you to dynamically construct the search pattern as a string, and is useful when the pattern is not known ahead of time.

To use regular expressions to validate a string you need to define a pattern string that represents the search criteria, then use a relevant string method to denote the action (ie: search, replace etc).

Last month I wrote about regular expressions in Java, today I’ll show you how to use regular expression in Java Script to validate email address.

Here is the code to validate email address in Java Script using regular expression.

On the final line we call test method for our regular expression and pass the email address as input.

The goal of is to provide a cross framework and cross language way of validating data.

provides a declarative way of validating javascript objects.

It is unit tested with 100% code coverage and can be considered fit for production.

Once you master the pattern language, most validation tasks become trivial.

You can perform complex tasks that once required lengthy procedures with just a few lines of code using regular expressions.
