Can I add to a javascript object once its defined?
<p>I have the following javascript code:</p>

<pre><code>var oLink = {
        title:   $link.attr('title') || '',
        row:     $link.attr('data-row') || ''
    }
</code></pre>

<p>Is it possible to add another field <strong>once these fields have already been defined</strong> so as to achieve:</p>

<pre><code>var oLink = {
        viewUrl: $link.attr('data-href') || '',
        title:   $link.attr('title') || '',
        row:     $link.attr('data-row') || ''
    }
</code></pre>
