从表中获取ID

Question

I have a table of data from mysql to php

echo"<table id='tableedit'>"

echo"<tr>";
echo"<td class='get'>";
echo $id;
echo $title;
echo"<tr>";
echo"<td>";

echo"<tr>";
echo"<td class='comments'>";
echo $comments;
echo"</tr>";
echo"</td>";

So the information looks like:

ID:1
Title:something
Comments:something..

And there are more as the user inputs them. I am trying to enable the user to edit their comments using an inline edit:

 $(document).ready(function() {


    $('#tableedit tr td.comments').click(function () {
     var html = $(this).text();
     var input = $('<input type="text"; />');
    input.val(html);
               $(this).replaceWith(input);
                          $('#tableedit input').focus();
                            $('#tableedit input').blur(function () {

                              var review =(this.value);
               $(this).replaceWith(review);                                   
             //$.post('editcomments.php',{review:review});

            });                              
       });
  });

The inline text edit is working fine but the problem is i want to post the comments to mysql data via ajaxhowever i want to get the $idvalue of each comments from the table. I have tried this which gives me a null value

    var id = $(this).(html).parent('#tableedit').find('tr td #get');
alert(id);  //gives a null value

Any advice?

You could add the id as an attribute:

echo "<td data-id='$id' class='comments'>";

and then you could easily retrieve it with:

var id = $(this).data('id');
