count values of checked checkbox
<p>I want to get the total value of all checked checkboxes. What i've tried is this:</p>

<pre><code>$("input[type=checkbox]:checked").each(function() {
            total_modules += parseFloat($(this).val());
        });
        $("#total_modules").text(total_modules.toFixed(2));
</code></pre>

<p>This didn't work.</p>

<p>I hope someone can help me.</p>

<p>Thanks in advance!</p>

<p>PS: I fixed it, this is my new code:</p>

<pre><code>function calculation()
    {
    $("input[type=checkbox]:checked").each(function() {
            total_modules += parseFloat($(this).val());
        });
        $("#total_modules").text(total_modules.toFixed(2)); 
    }
    calculation();

    $("input[type=checkbox]").click(function()
    {
        calculation();
    });
</code></pre>

<p>Thank you all</p>
