title: How to get input text value from inside td
body: <pre><code>&lt;tr&gt;
   &lt;td&gt;
        &lt;input type="text" name="desc[]"&gt;
   &lt;/td&gt;
   &lt;td&gt;
        &lt;input type="text" name="duration[]"&gt;
   &lt;/td&gt;
   &lt;td&gt;
        &lt;input type="text" name="start[]" class="start"&gt;
   &lt;/td&gt;
   &lt;td&gt;
         &lt;input type="text" name="wait[]"&gt;
   &lt;/td&gt;
   &lt;td&gt;
         &lt;input type="text" name="end[]"&gt;
   &lt;/td&gt;
   &lt;td&gt;
        &lt;input type="text" name="phone[]"&gt;
   &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>I have such multiple rows. I need to fetch the values off all tds on keyup event on the td with input name start(and i also need to avoid values of desc[] and phone[]). Since they are many i cannot go with ids, need help in parent child approach with jquery.</p>
  
  <p>I was able to reach parent tr on keyup event on the above mentioned td but not able to access values of input field in other tds. the jquery code i used</p>
  
  <pre><code>$(document).ready(function(){
      $(".start").keyup(function(){
          alert($(this).parent().get(-3).tagName);
      })
  });
  </code></pre>
