select only 1st level of nested elements
<p>We have the following html:</p>

<pre><code>&lt;div&gt;
&lt;div class="bord" id="1"&gt;
    parent1
    &lt;div class="bord"&gt;
        child1
        &lt;div class="bord"&gt;
            subchild1
        &lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
-----------
&lt;span&gt;
&lt;div class="bord" id="2"&gt;
    parent1
    &lt;div class="bord"&gt;
        child1
        &lt;div class="bord"&gt;
            subchild1
        &lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;
&lt;/span&gt;
</code></pre>

<p>need to have function that will select with call</p>

<pre><code>a=$('.bord').new_function();
</code></pre>

<p>only elements marked in sample as id="1" and id="2";
if after that:</p>

<pre><code>b=a.new_function();
</code></pre>

<p>it should select child1s only</p>

<pre><code>b.new_function(); 
</code></pre>

<p>should be able to select subchild1s</p>

<p>I tried several ways and have no ideas now. </p>
