title: this + class selector?
body: <p>Currently, I have three input fields. When one has text in it, an anchor will show to the right. Currently though, when I type in one, the anchor will appear for all three input fields.</p>
  
  <p>What I need to know is, is there a this + class selector for jQuery? For example:
  <code>$(this + '.more')</code></p>
  
  <p>This is something I need right now and I can't seem to find it or anything similar in the jQuery API.</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;div id="max"&gt;
  
    &lt;span class="sub title"&gt;Max&lt;/span&gt;
    &lt;input type="text" /&gt;&lt;a class="more" href="" onclick=""&gt;...more&lt;/a&gt;
  
  &lt;/div&gt;&lt;div id="onepoint"&gt;
  
    &lt;span class="sub title"&gt;One Point&lt;/span&gt;
    &lt;input type="text" /&gt;&lt;a class="more" href="" onclick=""&gt;...more&lt;/a&gt;
  
  &lt;/div&gt;&lt;div id="leftover"&gt;
  
    &lt;span class="sub title"&gt;Leftover&lt;/span&gt;
    &lt;input type="text" /&gt;&lt;a class="more" href="" onclick=""&gt;...more&lt;/a&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>Javascript:</p>
  
  <pre><code>$('#max input[type=text], #onepoint input[type=text], #leftover input[type=text]').on('change', function() {
    if( $(this).val() == '' ) {
      $('.more').hide();
    } else {
      $('.more').show();
    }
  });
  </code></pre>
  
  <p>If I have the selector as just <code>$('.more')</code> all three toggle when I only want the right one too. How would I do this?</p>
