$.get( ... don't work for me

Hello.
Here is 'test.html':


  1. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <script type="text/javascript" src="js/jquery.js"></script>
    </head>
    <body>

    <script>

    function loadBox()
    {
    $.get("test.php", function(data){
    alert("Data Loaded: " + data);
    });
    }
    </script>

    <form>
    <input name="a" type="button" OnClick="loadbox();" />
    </form></body>



















and content of test.php is simple:

  1. <?php
    echo 'Hi';
    ?>


But it don't even work.
Function alert("Data Loaded: " + data); is never called. Can you help me pls?
I know that will be "noob problem", but I just starts with jQuery, so thank you for any kind of help.
