Email validating regular expression

It won't go to the very basics of regexps since there are some very good tutorials available in the web.

This article focuses on using regexp to validate email addresses.

The period separated character sequences in the local-part can now include all the special characters defined in the RFC.

Characters "$", "*", " " "^", "{" and "|" all have their special meanings in regular expressions so they must be escaped with a backslash.

The fully compliant RFC-822 email regex is nothing to be trifled with; in fact, it is a behemoth.

As such, I recommend using only a simple regular expression for this task.

So I updated the Java regular expression to validate email address.

I am pretty sure that the following Java regular expression will validate any email address.

If it doesn't find any matches then it will fail the validation and the function will return false, if the match returns true then the email will be of a correct format and the function will return true.On the final line we call test method for our regular expression and pass the email address as input.If the input email address satisfies our regular expression, ‘test’ will return true otherwise it will return false. You can call this method whenever you want to validate email address.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.
