In your fiddle, you didn't select jQuery from the library dropdown.
Secondly, you should avoid submitting the form from within the submit handler, instead just preventDefault if there is a validation error.
$('.form-horizontal').on('submit', function (e) {
var name = $('#name').val();
if (!name) {
showError();
e.preventDefault();
}
});
If you really want to keep the code as it was, you need to call the forms submit function, not the jQuery submit function:
$('#contact-form')[0].submit();
// or
$('#contact-form').get(0).submit();
Here, [0] or .get(0) is giving you the plain JavaScript DOM element with no jQuery wrapper, and with this you can call submit() .

HTML5 provides input validation, you can set in order to tell the browser that your html view is HTML5.
//Set your doctype for HTML5.
<!doctype html>
<html>
<head>
<title></title>
</head>
<body>
<form id="the_form">
//here html5 will not submit if the box is empty or does not meet the email
//addres format.
<input type="email" name="email" id="email" placeholder="Enter email..">
<input type="submit" value="send">
</form>
</body>
</html>
If you dont want to use HTML5, you could also make a simple javascript code to not submit if the input is empty.
<html>
<head>
<title></title>
<script type="text/javascript">
window.onload = init();
function init(){
//get form.
var form = document.getElementById("the_form");
form.onsubmit = email_validation;
}
function email_validation(){
email = document.getElementById("email");
if(email.value == ''){
//return false to avoid submission.
return false;
}
else{
//do whatever code.
}
}
</script>
</head>
<body>
<form id="the_form">
<input type="text" name="email" id="email" placeholder="Enter email..">
<input type="submit" value="send">
</form>
</body>
</html>
with this way, your email will be validated before is sent, hope this work for you.
