Firebug: "The 'charCode' property of a keyup event should not be used. The value is meaningless."
<p>I'm building a calculator, and am using the following:</p>

<pre><code>jQuery(function($) {
    $('#Quantity').keyup(function() {
        console.log($(this).val());
    });
});
</code></pre>

<p>Q1: Is keyup() the right event to be using?</p>

<p>Q2: Why is Firebug telling me "The 'charCode' property of a keyup event should not be used.  The value is meaningless"?  I noticed that it's doing the same thing as I type this question into Stackoverflow, so I must not be doing something too awfully wrong.</p>
