jQuery syntax error
<p>I am trying to set saveData when there is at least one field filled in:</p>

<pre><code>    $(document).ready(function () {
        $(":input").each(function() {
            if($(this).val() != "") 
                window.setInterval(saveData, 5000);
        }
    });
</code></pre>

<p>There is a syntax error <code>Expected ')'</code> in this code.</p>

<p>What am I missing here?</p>
