I need to send ajax data to the PHP POST method, but I get undefined index "name". I have tried including dataType: json in ajax and json_encode().
In console, I am getting the whole HTML code when logging success: function(data){}.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<?php
echo $_POST["name"];
?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script type="text/javascript">
var name="KO";
$.ajax({
type:"POST",
url: 'ajax.php',
data:{ "name": name},
success: function(data){
console.log(data);
}
});
</script>
</body>
</html>
