Code for validating email in javascript

Our validation script will ensure that the user enters their name before the form is sent to the server. Try pressing the Send Details button without filling anything in the "Your Name" field.

There are two main methods for validating forms: (usually done using Java Script).

At the end, there's a little exercise to keep you busy too!

Form validation is the process of checking that a form has been filled in correctly before it is processed.

Great for "required fields" such as email addresses!

This tutorial will show you how to create a Java Script-enabled form that checks whether a user has filled in the form correctly before it's sent to the server. First we'll explain why form validation is a useful thing, and then build up a simple example form, explaining things as we go along.

A while ago I put up a Password Strength Checker using Java Script and Regular Expressions.

On that same note, you can also check the structure of an email address utilizing the same regular expression (regex) methodology.

Let's build a simple form with a validation script.

The form will include one text field called "Your Name", and a button.

If your form element has the id=”emailaddress” and you add a form on Submit=”return check Email();“, this is a Javascript function that you can utilize to return an alert if the email address has a valid structure or not:()[]\.,;:[email protected]"]+)*)|(".+"))@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-z A-Z-0-9]+.)+[a-z A-Z]{2,}))$/; if (!

Shows you how to write a script that ensures your form is filled in correctly before it's sent to your server.
