Validation can be defined by many different methods, and deployed in many different ways.
Server side validation is performed by a web server, after input has been sent to the server.
That outside help can take the form of some server-side coding on your application, or a third party service that you can use directly from the browser.
Most often, the purpose of data validation is to ensure correct user input.
Validating email is a very important point while validating an HTML form.
An email address must contain at least a ‘@’ sign and a dot (.).
Also, the ‘@’ must not be the first character of the email address, and the last dot must at least be one character after the ‘@’ sign.
I have a requirement to validate an email address entered when a user comes out from the textbox.
I have googled for this but I got form validation JScript; I don't want form validation. I have written below JScript but "if email invalid it's not returning the same page".
In forms when using email ID fields it is a good idea to use client side validation along with your programming language validation.
