How to give mail pattren using jquery

You can use jQuery to validate and format email addresses using various plugins and methods. Here are a few examples:

Method 1: Using a regular expression

function validateEmail(email) {
  var re = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;
  return re.test(email);
}

// Example usage:
var email = "[email protected]";
if (validateEmail(email)) {
  console.log("Email is valid");
} else {
  console.log("Email is not valid");
}

This regular expression checks for the following:

^ matches the start of the string
[a-zA-Z0-9._%+-]+ matches one or more characters that are letters (both uppercase and lowercase), numbers, dot (.), hyphen (-), underscore (_), percent (%), or plus sign (+)
@ matches the @ symbol
[a-zA-Z0-9.-]+ matches one or more characters that are letters (both uppercase and lowercase), numbers, dot (.), or hyphen (-)
\. matches a period (.) character
[a-zA-Z]{2,} matches the domain extension (it must be at least 2 characters long)
$ matches the end of the string

Method 2: Using a jQuery plugin

// Include the jQuery validation plugin
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/jquery.validate.min.js"></script>

// Example usage:
var email = "[email protected]";
if ($.validator.methods.email.test(email)) {
  console.log("Email is valid");
} else {
  console.log("Email is not valid");
}

This method uses the jQuery Validation plugin, which provides a built-in method for validating email addresses.

Method 3: Using a custom jQuery function

$.fn.email = function(email) {
  var re = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;
  return re.test(email);
};

// Example usage:
var email = "[email protected]";
if ($("#email").email()) {
  console.log("Email is valid");
} else {
  console.log("Email is not valid");
}

This method defines a custom jQuery function called email that takes an email address as an argument and returns a boolean indicating whether the email address is valid.

Method 4: Using a jQuery library

// Include the jQuery library
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

// Include the jQuery email library
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/jquery.email.min.js"></script>

// Example usage:
var email = "[email protected]";
if ($.email(email)) {
  console.log("Email is valid");
} else {
  console.log("Email is not valid");
}

This method uses the jQuery Email library, which provides a simple way to validate email addresses.

Remember to adjust the regular expression or plugin settings according to your specific requirements.
