My result in my jQuery gives NaN
<p>I am getting <code>NaN</code> as result and its beacuse my jquery is multiplying numbers that look like <code>"204,3 * 3"</code></p>

<p>How can I deal with it? </p>

<p>I cant change the price, so what can I do?</p>

<p><code>"234 * 2"</code> works fine as soon as the number have <code>','</code> I get <code>NaN</code>.</p>

<pre><code>&lt;script type="text/javascript"&gt;
    $('.quantity').keyup(function () {
        var parent = $(this).parent(),
            price = parent.find('.price').html(),
            quantity = parent.find('.quantity').val(),
            result = price * quantity;
        parent.find('.price2').html(result);
    });
&lt;/script&gt;

     &lt;span class="price"&gt;69,9&lt;/span&gt;
     &lt;input type="text" class="quantity"&gt;    
     &lt;span class="price2"&gt;69,9&lt;/span&gt;
     &lt;span class="total"&gt;Total:&lt;/span&gt;
     &lt;div class="line2"&gt;&lt;/div&gt;
</code></pre>
