Difference between ('#ID') and $('#ID') selectors in jquery
<p>What is the difference between these two selectors: <code>('#ID')</code> and <code>$('#ID')</code> in jQuery? </p>

<p>When I am calling my function <code>checkSpecialChars('#txtCreateSet')</code>, it does not work and shows the following error message:</p>

<pre><code>error Object doesn't support this property 
</code></pre>

<p>However, when I call my function like the following: <code>checkSpecialChars($('#txtCreateSet'))</code>, it works. Why is this the case?</p>
