Question

I’m retrieving data from mysql like this structure =>

echo "<table id='postI" . $chat_row['id'] . "'>";
echo "<tr>";
      echo "<td><p class='post_author'>" . $chat_row['user_name'] . "</p><a href='javascript: void(0)' class='edit_post_a'><div class='edit_post'></div></a></td>";
echo "</tr>";
echo "<tr>";
      echo "<td><p class='posted_on'>" . $chat_row['posted_on'] . "</p></td>";
echo "</tr>";
echo "<tr>";
      echo "<td><br></td>";
echo "</tr>";
      echo "<tr>";
echo "<td><p class='posted_msg'>" . $chat_row['message'] . "</p></td>";
      echo "</tr>";
echo "</table>";

and I can get the table id with this expression =>

$(".edit_post_a").bind("click",function(){
    var tb_id = $(this).closest("table").attr("id"); //  works , gets the id of the table
    alert($(tb_id + ".posted_msg").text()); // don't work, gets nothing , just alert box 
    });

My problem is that want to know text of the third p, what I’ve tried =>

alert($("#" +tb_id + ".posted_msg").text());
alert($("#" +tb_id).find("p").last().text());
alert($("#" +tb_id + " p:nth-child(3)").text());

nothing works , get empty alert box , I’ve no idea whats wrong ? how can I fix it ? thanks

HTML code =>

<table id='postI245'>
<tr>
    <td><p class='post_author'>USER</p><a href='javascript: void(0)' class='edit_post_a'><div class='edit_post'></div></a>
    </td>
</tr>
<tr>
    <td><p class='posted_on'>DATE</p></td>
</tr>
<tr>
    <td><br></td>
</tr>
<tr>
    <td><p class='posted_msg'>MSG</p></td>
</tr>
</table>

and so on …

Answer 1

Your selector selects nothing, you should add # for selecting an element by id.

var txt = $('#'+tb_id + " .posted_msg").text();

or:

var txt = $(this).closest("table").find("p:eq(2)").text()
