<p>If you want to do it in pure javascript,<br> then pass <code>this</code> to your <code>ajax_answer</code> function from <code>onclick</code> event like below </p> <pre><code><?php while( $u = mysql_fetch_array( $result ) ) { ?> <tr> <td><?php echo $u['question_id'];?></td> <td><?php echo $u['question'];?></td> <td> <input type="hidden" value="<?php echo $u['question_id'];?>" /> <input type="text" /> <a href="#" onclick="ajax_answer( this );">Send Answer</a> </td> </tr> <?php } ?> </code></pre> <p>and your javascript will be... </p> <pre><code><script type="text/javascript"> function ajax_answer( elem ) { var question_id = elem.parentElement.children[0].value; var answer = elem.parentElement.children[1].value; /// do your request here return false; } </script> </code></pre> <p>And the same with jQuery.<br> Add <code>name</code> attribute to those input elements, and add a <code>classname</code> to <code>anchor</code> element</p> <pre><code><?php while( $u = mysql_fetch_array( $result ) ) { ?> <tr> <td><?php echo $u['question_id'];?></td> <td><?php echo $u['question'];?></td> <td> <input type="hidden" name="question_id" value="<?php echo $u['question_id'];?>" /> <input type="text" name="answer" /> <a href="#" class="send_answer">Send Answer</a> </td> </tr> <?php } ?> </code></pre> <p><strong>Javascript</strong><br> add the <code>onclick</code> event handler dynamically. Now your function <code>ajax_answer</code> accepts two parameters <code>question_id</code> and <code>answer</code>, we will pass those two parameters through the <code>click</code> event handler</p> <pre><code><script type="text/javascript"> $(function() { $("a.send_answer").on("click", function( event ) { event.preventDefault(); var td = $(this).parents("td:first"); var qid = $("input[name=question_id]", td).val(); var ans = $("input[name=answer]", td).val(); ajax_answer( qid, ans ); }); }); function ajax_answer( question_id, answer ) { /// do your request here } </script> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
