Validating an email address with javascript

If you use the following script and Perl source you will know how to validate an entire form at once, displaying a series of error messages that your reader can then go back and fix.By Bill Evjen Reuters December 2003 Applies to: Microsoft® ASP. NET validation server controls that are at your disposal.This takes a lot of resources and makes for a slower-paced form for the user.Nothing is more annoying to a user who is on a dial-up connection than clicking the Submit button on the form and then waiting for 20 seconds to find out that they didn't enter their password correctly.You can check for many types of information, as you learn in the rest of this article.Data collection on the Internet is one of its most important features, so you must make sure that the data you collect has value and meaning.After the user enters data into a Web form, clicks the Submit button, and sends the form data to the server as a request, you can perform server-side validation on the data.If the data is incorrect or not valid, you can send back a response stating this.

This can make filling out the form tedious, and people might stop in the middle.

Obviously, this may cause people to leave your site for another.

The bad thing about server-side validation is that it requires trips back and forth to the server.

You ensure this by eliminating any chance that the information collected does not abide by the rules you outline. NET don't know the difference between client-side and server-side validation.

You must understand these two different ways of validating the data users input into a Web form.

This paper focuses on a series of controls that stand out from the rest—.
