Find object's value
<p>Is there any <strong>not loop-based</strong> approach in <strong>JavaScript</strong> or <strong>JQuery</strong> that can check presence of some VALUE from object's properties. I mean here if I have </p>

<pre><code>obj = { prop1:val, prop2:val2 }
</code></pre>

<p>is that possible with maybe one statement check is <strong>val2</strong> presence among values of <strong>obj</strong> ?</p>

<p><strong>UPDATE 1:</strong> The loop here is not the key! I can use loop if it is wrapped in some <strong>JQuery</strong> predefined function!</p>

<p><strong>UPDATE 2:</strong> 
Writing a hand-made function is not so elegant, I think. I would like to find some library based solution for such a common and usual problem.</p>
