How come my JQuery script doesn't work?

I am not sure why this doesn't work, all the articles I read online make it seem like this should work. Well, here's my html code: ()

<!doctype html>
<html>
<head>
<script src = "http://code.jquery.com/jquery-latest.min.js" type = "text/javascript"></script>
<script src = "showmotto.js" type = "text/javascript"> </script>
</head>

<body>

<table>

<?php

    $pdo = new PDO('mysql:host=localhost;dbname=test', 'root', '');
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);  
    $sth = $pdo->query('SELECT * from users');
    $sth->setFetchMode(PDO::FETCH_ASSOC);   

    while( $row = $sth->fetch() )
    {
        echo "<tr><td class = \"users\" data-motto = '{$row['motto']}' >{$row['username']}</td></tr>";      
    }

    $pdo = null;

?>

</table>

</body>

</html>

And here is show-motto.js. My goal is to alert the user when they mouseover on the table with the information in data-motto. But I haven't gotten that far yet, because for some reason the mouseover event isn't working

$('td.users').live('mouseover', function()
    alert(0);
});

I've also tried $('.users') but it doesn't work either.

What am I doing wrong?

In the latest version of jQuery, live has been removed.

What you can do is this :

$(document).on('mouseover', 'td.users', function() {
    alert(0);
});

or, as the elements are all created initially :

$(function(){
   // put all your code inside this block
   $('td.users').on('mouseover', function() {
      alert(0);
   });
});

Another solution, similar to the second one, would be to have all your JS code in a script element located at the end of the body (that is after the table).

You also add a missing opening bracket. This problem you should have detected using the console of your browser where all errors are displayed.

Because live function is deprecated from the recent versions of jquery ...instead of that use on like

$(function(){
    $('td.users').on('mouseover', function()
        alert(0);
    });
})

or 

$(document).ready(function(){
    $('td.users').on('mouseover', function()
        alert(0);
    });
})
