Sometimes we want to send form data but we don't want to reload page. In this case best option is send data by ajax and jQuery. In this example we used version 1.10.2 of jQuery.
HTML code:
<form id="FORMID" accept-charset="UTF-8" action="action.php" method="POST">
<input type="text" name="username" id="username" placeholder="Write username">
</form>;
Javascript code:
$('#FORMID').on('submit', function(e) {
$.post(
$(this).prop('action'),
{
"username": $(this).find('input[name=username]').val()
},
function(data) {
alert(data.result);
},
'json'
);
return false;
});
php (action.php) code:
<?php
$username = $_POST['username'];
$ret = array();
$ret['result'] = 'OK';
return json_encode($ret);
Best regards!
