Check if an object (not an element) really exists with js/jQuery
<p>I got this string of code, data is value returned inside a success callback in an ajax environment:</p>

<pre><code>$('#cpt_rspp_value').text(data.Payload.Clerks.rspp.full_name)
$('#cpt_ddl_value').text(data.Payload.Clerks.ddl.full_name)
$('#cpt_rls_value').text(data.Payload.Clerks.rls.full_name)
$('#cpt_mc_value').text(data.Payload.Cler.mc.full_name)
$('#cpt_se_value').text(data.Payload.Clerks.se.full_name)
</code></pre>

<p>If, <code>rspp</code> really exists inside the DB the object <code>data.Payload.Clerks.rspp.full_name</code> will be  present, so I can put it in right place (i.e: <code>#cpt_rspp_value</code>).
But, alas, if that object doesn't exist, the js interpreter will stop, and so, even if next objects <code>data.Payload.Clerks.ddl.full_name</code>, <code>data.Payload.Clerks.rls.full_name</code> and so on, will be present, that row will never been processed. </p>

<p>I should "if" any lines, but how? <code>if(data.Payload.Clerks.rspp.full_name)</code> and <code>if(data.Payload.Clerks.rspp.full_name != null)</code> don't resolve the issue. 
What can I do?</p>
