Get Distinct name of elements with a class using jquery
<p>I have the following HTML:</p>

<p>Radio button list(s):</p>

<pre><code>&lt;input name="rdLst163" class="required_Mandatory_RbtLst" id="rdLst163_1" onclick="fn("1631");" type="radio" value="1"/&gt;
&lt;input name="rdLst163" class="required_Mandatory_RbtLst" id="rdLst163_2" onclick="fn("1632");" type="radio" value="2"/&gt;
&lt;input name="rdLst163" class="required_Mandatory_RbtLst" id="rdLst163_3" onclick="fn("1633");" type="radio" value="3"/&gt;

&lt;input name="rdLst164" class="required_Mandatory_RbtLst" id="rdLst164_1" onclick="fn("1641");" type="radio" value="1"/&gt;
&lt;input name="rdLst164" class="required_Mandatory_RbtLst" id="rdLst164_2" onclick="fn("1642");" type="radio" value="2"/&gt;
&lt;input name="rdLst164" class="required_Mandatory_RbtLst" id="rdLst164_3" onclick="fn("1643");" type="radio" value="3"/&gt;
</code></pre>

<p>Checkbox list(s):</p>

<pre><code>&lt;input name="chLst165" class="required_Mandatory_ChkLst" id="chkLst165_1" onclick="fn("25");" type="checkbox" value="1"/&gt;
&lt;input name="chLst165" class="required_Mandatory_ChkLst" id="chkLst165_2" onclick="fn("25");" type="checkbox" value="2"/&gt;
&lt;input name="chLst165" class="required_Mandatory_ChkLst" id="chkLst165_3" onclick="fn("25");" type="checkbox" value="3"/&gt;

&lt;input name="chLst166" class="required_Mandatory_ChkLst" id="chkLst166_1" onclick="fn("25");" type="checkbox" value="1"/&gt;
&lt;input name="chLst166" class="required_Mandatory_ChkLst" id="chkLst166_2" onclick="fn("25");" type="checkbox" value="2"/&gt;
&lt;input name="chLst166" class="required_Mandatory_ChkLst" id="chkLst166_3" onclick="fn("25");" type="checkbox" value="3"/&gt;
</code></pre>

<p>and the following jQuery :</p>

<pre><code>&lt;script&gt;
$(document).ready(function () {
  $('.required_Mandatory_ChkLst[name!=]'); 
  $('.required_Mandatory_RbtLst[name!=]');
// result is fetching all 6 elements. I need only distinct element names [here 2 elements] in each class.
});
&lt;/script&gt;
</code></pre>

<p>how can I get distinct element names of class in jQuery?</p>

<p>Required result: </p>

<pre><code>["rdLst163", "rdLst164"]  
["chLst165", "chLst166"]
</code></pre>
