<form action="submit.php" method="post" id="registerSubmit">
    <input type="text" name="name" id="name" placeholder="Name">
    <button id="submit" type="submit">Submit</button>
</form>
<div id="result"></div>

$(document).ready(function(){
    $("#registerSubmit").submit(function( e ) {
    e.preventDefault();
        $.ajax({
            url: "load.php",
            method: "post",
            data: "",
            dataType: "text",
            success: function(Result) {
                $('#result').text(Result)
            }
        })

    });

<?php
$name = $_POST['name']; 
echo $name;
?>
