How to validate forms in jQuery
Here are a few example of how the jQuery Validation can be used to validate forms. These examples were coded to demonstrate the possibilities and results that can be achieved using this JavaScript plugin. It is for you to decide how to skin and customize the functionalities of your form(s).
Example:-
———————————-
<html>
<head>
<link href=”//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.no-icons.min.css” rel=”stylesheet”>
<script src=”//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js”></script>
<link href=”runnable.css” rel=”stylesheet” />
<!– Load jQuery and the validate plugin –>
<script src=”//code.jquery.com/jquery-1.9.1.js”></script>
<script src=”//ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js”></script>
<!– jQuery Form Validation code –>
<script>
// When the browser is ready…
$(function() {
// Setup form validation on the #register-form element
$(“#register-form”).validate({
// Specify the validation rules
rules: {
firstname: “required”,
lastname: “required”,
email: {
required: true,
email: true
},
password: {
required: true,
minlength: 5
},
agree: “required”
},
// Specify the validation error messages
messages: {
firstname: “Please enter your first name”,
lastname: “Please enter your last name”,
password: {
required: “Please provide a password”,
minlength: “Your password must be at least 5 characters long”
},
email: “Please enter a valid email address”,
agree: “Please accept our policy”
},
submitHandler: function(form) {
form.submit();
}
});
});
</script>
</head>
<body>
<h1>Register here</h1>
<!– The form that will be parsed by jQuery before submit –>
<form action=”” method=”post” id=”register-form” novalidate=”novalidate”>
<div class=”label”>First Name</div><input type=”text” id=”firstname” name=”firstname” /><br />
<div class=”label”>Last Name</div><input type=”text” id=”lastname” name=”lastname” /><br />
<div class=”label”>Email</div><input type=”text” id=”email” name=”email” /><br />
<div class=”label”>Password</div><input type=”password” id=”password” name=”password” /><br />
<div style=”margin-left:140px;”><input type=”submit” name=”submit” value=”Submit” /></div>
</form>
</body>
