How handle 'null' values in a json search
<p>still new to JavaScript, I am searching for numbers in my JSON, but the JSON has a lot of null values. How can I ignore the null values in my search?</p>

<pre><code>$.each(geojson.features, function (i, v) {
    if (v.properties.code.toString().search((/2/i)) != -1) {
        Count++;
    }
});
</code></pre>

<p>Thanks for the help in advance. </p>
