jQuery "required email" is the method to validate or check email if the element is empty (text input) or wrong email type entered

jQuery Email Validation :

jQuery "required email" is the method to validate or check email  if the element is empty (text input) or  wrong email type entered .We can validate our email in another type by writing the "email: true" in the rules tag. Like as in this example.

<script type="text/javascript">

$(document).ready(function() {

$("#commentForm").validate({

rules: {

field: {

required: true,

email: true

}

}

});

</script>

Getting Started with jQuery "required email" :

In this example there are the following steps which are used to make jQuery "required email". This example  Makes "field" always required. Nothing, blanks and wrong email type are invalid.

Step 1: In the first step we make css to create the text field background, height, width and other things

cmxform.css :

form.cmxform {

width: 370px;

font-size: 1.0em;

color: #333;

}

form.cmxform legend {

padding-left: 0;

}

form.cmxform fieldset {

border: none;

border-top: 1px solid #C9DCA6;

background-color: #F8FDEF;

}

form.cmxform label.error, label.error {

color: red;

font-style: bold

}div.error { display: none; }input {border: 1px solid black; }

Step 2: In the second step we make the connection with jquery plugins which are jquery1.js , jquery.validate.js and connection with css page.

<link rel="stylesheet" type="text/css" media="screen" href="../../plugin/cmxform.css" />

<script src="../../plugin/jquery1.js" type="text/javascript"></script>

<script src="../../plugin/jquery.validate.js" type="text/javascript"></script>

Step 3: In the third step we will make the HTML part, the HTML required for  the front end for this text field .With the help of this text field we check that the required field should not be empty and it should not be wrong email type.

<html>

<body>

<form class="cmxform" id="commentForm" method="post" action="">

<fieldset>

<p>

E-Mail:<input id="email" name="email" class="required email" />

</p>

<p>

<input class="submit" type="submit" value="Submit"/>

</p>

</fieldset>

</form>

</body>

</html>

Step 4: In the last step we will make the jQuery part , the jQuery required for  the checking the validation for specified  text field .With the help of this jQuery  we check that the required field should not be empty and validated field should be of the email type.

<script type="text/javascript">

$(document).ready(function() {

$("#commentForm").validate();

});

</script>

After using the following steps the the required text field will validated and we can check the validation by clicking on the submit button.
