Javascript code for validating email address

I'm sure there's a few more things you can do to improve the quality.

If the data entered by a client was incorrect or was simply missing, the server would have to send all the data back to the client and request that the form be resubmitted with correct information.

This was really a lengthy process which used to put a lot of burden on the server.

With the two methods, CGI and Java Script, you've validated an HTML form so that more of the parts that are sent to you are accurate.

This comes up often:… You can look up great references from Douglas Crockford on some Do's and Don'ts of Javascript to also improve your skills. You Tube will have many of his lectures for review.

There's a number of advantages doing that, including improved debugging if you realize a specific parameter doesn't have a value passing through properly, or setting specific behavior if NULL is returned from is Valid Email.

Form validation normally used to occur at the server, after the client had entered all the necessary data and then pressed the Submit button.
