Using jQuery to build table rows from AJAX response(json)

Question

Possible duplicate Nested elements

I'm getting from server-side ajax response (Json) and I'm trying to dynamically create table rows and append them to an existing table with id=records_table.

I tried to implement the solution in possible duplicate but it failed.

My response looks like that:

    '[{
      "rank":"9",
      "content":"Alon",
      "UID":"5"
     },
     {
       "rank":"6",
       "content":"Tala",
       "UID":"6"
    }]'

the require result is something like that:

<tr>
   <td>9</td>
   <td>Alon</td>
   <td>5</td>  
</tr>
<tr>
   <td>6</td>
   <td>Tala</td>
   <td>5</td>  
</tr>

I want to do something without parsing the Json so I tried to do the following, which of course was a disaster:

    function responseHandler(response)
    {

        $(function() {
            $.each(response, function(i, item) {
                $('<tr>').html(
                    $('td').text(item.rank),
                    $('td').text(item.content),
                    $('td').text(item.UID)
                ).appendTo('#records_table');

            });
        });


    }

From my solution I get only one row with the number 6 in all cells. What am I doing wrong?

Use .append instead of .html

var response = "[{
      "rank":"9",
      "content":"Alon",
      "UID":"5"
     },
     {
       "rank":"6",
       "content":"Tala",
       "UID":"6"
    }]";

// convert string to JSON
response = $.parseJSON(response);

$(function() {
    $.each(response, function(i, item) {
        var $tr = $('<tr>').append(
            $('<td>').text(item.rank),
            $('<td>').text(item.content),
            $('<td>').text(item.UID)
        ); //.appendTo('#records_table');
        console.log($tr.wrap('<p>').html());
    });
});
