Having a form submit on every keypress
<p>I have a currency calculator that requires buttons to convert to/from currencies. I'd like to make it so that it converts (runs the form) as soon as anything is typed in. Currently, my jQuery that handles the button click looks like this (this is one of two click handlers):</p>

<pre><code>        $('#convertFromButton').click(function() {
            $("#currencySelectValue2").val($("#currencySelect").val());
            $("#btcValueForm").val($("#btcValue").val());
            $.post("php/convertFromForm.php", $("#convertFromForm").serialize(), function(data){ 
                $('#fromCurrencyValue').removeClass('intra-field-label');
                $('#fromCurrencyValue').val(data);
            });
        });
</code></pre>

<p>The first text field is <code>#fromCurrencyValue</code> and the 2nd one is <code>#btcValue</code>.</p>

<p>How can I get it to work in the manner I described?</p>
