Javascript for validating web site address

If the entered data follows all of the specified rules, it is considered valid; if not, it is considered invalid.

When an element is valid, the following things are true: Adds a custom error message to the element; if you set a custom error message, the element is considered to be invalid, and the specified error is displayed.

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.

Because you're already using Java Script, using a polyfill isn't an added burden to your website or web application's design or implementation.

Let's see how to use this API to build custom error messages.

This is building on my previous post on how to use regular expressions with j Query. Update 12/05/13: Separated into versions for testing.

//reported to validate incorrectly: [email protected] as true /[A-Z0-9._% -] @[A-Z0-9-] .

For legacy browsers, it's possible to use a polyfill such as Hyperform to compensate for the lack of support for the constraint validation API.

If the information is correct, the application allows the data to be submitted to the server and (usually) saved in a database; if the information isn't correct, it gives you an error message explaining what needs to be corrected.

Form validation can be implemented in a number of different ways.

The argument to this method is the email address you want to validate.

In the method body we define a variable (’email Pattern’) and assign a regular expression to it.
