javascript - How to avoid page reload in php form submission

I am currently using php in my html page and there is an action in the same page which gets executed upon form submission. Currently whole form gets reloaded while I want the php action to be run in the background with out reloading. How do I do it. I would also want to clear the text box after submit button is clicked. Following is the code I am currently using

<html>
<head>
</head>

<body>
    <form action="index.php" method="post"  role="form">
        <input type="email" placeholder="Enter email"  name="email_address">
        <button class="btn btn-primary custom-button red-btn">Sign Up</button>
    </form>

<?php



if(isset($_POST['email_address'])  !(trim($_POST['email_address']) == ''))

// do some action
}

?>
</body>

</html>

Note: Following code worked for me

<script type="text/javascript">
    $('#contactForm').submit(function () {
       $.post("mailer.php",$("#contactForm").serialize(), function(data){
       });
        return false;
    });
</script>

You need to use AJAX for this, for without reloading. Or, if you want to do it without disturbing the page, you need to set target.

Using AJAX

$("form").submit(function(){
  $.post($(this).attr("action"), $(this).serialize());
  return false;
});

Using target

<form action="index.php" method="post" role="form" target="_blank">
