如何将php变量传递给jquery AJAX?

I have started learning jquery AJAX. I have run into a problem, and was wondering if you guys could help me. I am trying to pass a php variable back to jquery, but it displays as [object Object]. I will be posting my code below.

index.html:

<!DOCTYPE html>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<script>
$(document).ready(function(){
    $("button").click(function() {
        $("p").text($.get("return.php"));
    });
});
</script>
</head>

<body>
<p>This is a test!</p>
<button>Click Here</button>
</body>
</html>

return.php:

<?php 
    $message = "Another test!";
    echo $message;
?>

So what is it that I need to do to pass php variable $message into the paragraph using jquery ajax?

I know I could simply do if I changed index.html to index.php, but then if $message later changes, I have to reload the page. I am trying to learn how to make dynamic content without having to reload the page.

Thanks ahead of time for any help you provide! :-)

    You'll have to wait until the data is returned before you can use it:

    $(document).ready(function(){
        $("button").click(function() {
            $.get("return.php", function(data) {
                 $("p").text(data);
            });
        });
    });
