Return the content from textarea with element inside
<p>I would like to make a script that would extract me everything within a defined element. In this exemple it's the <code>&lt;u&gt;</code> element.</p>

<p><strong>HTML</strong></p>

<pre><code>&lt;textarea cols="75" rows="25" id="textShit"&gt;&lt;u&gt;sd&lt;/u&gt;&lt;/textarea&gt;&lt;br&gt;
    &lt;input type="submit" name="submit" id="submit"/&gt;
    &lt;div id="res"&gt;&lt;/div&gt;
</code></pre>

<p><strong>JS</strong></p>

<pre><code>$(function(){
    $('#submit').on('click',function(){
        $('textarea:contains("u")').each(function() {
            //$('#res').html($(this).val()+'&lt;br&gt;');
            alert($(this).val());
        })
    });
});
</code></pre>

<p>I would like when I hit submit, in the <code>&lt;div class="res"&gt;</code>  it returns what's inside every <code>&lt;u&gt;</code>. </p>

<p>How to achieve this ?</p>
