jQuery append and remove dynamic table row

I can add many rows for a table, but I can't remove many rows. I only can remove 1 row per sequential add.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
    $("#addCF").click(function(){
        $("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" id="remCF">Remove</a></td></tr>');
        $("#remCF").on('click',function(){
            $(this).parent().parent().remove();
        });
    });
});
</script>

<table class="form-table" id="customFields">
<tr valign="top">
    <th scope="row"><label for="customFieldName">Custom Field</label></th>
    <td>
        <input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp;
        <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp;
        <a href="javascript:void(0);" id="addCF">Add</a>
    </td>
</tr>
</table>

You can see the code at http://jsfiddle.net/3AJcj/

I need help.

You only can have one unique ID per page. Change those IDs to classes, and change the jQuery selectors as well.

Also, move the .on() outside of the .click() function, as you only need to set it once.

http://jsfiddle.net/samliew/3AJcj/2/

$(document).ready(function(){
    $(".addCF").click(function(){
        $("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');
    });
    $("#customFields").on('click','.remCF',function(){
        $(this).parent().parent().remove();
    });
});

You can dynamically add and delete table rows like this in the image using jQuery..

Here is html part...

<form id='students' method='post' name='students' action='index.php'>

    <table border="1" cellspacing="0">
      <tr>
        <th><input class='check_all' type='checkbox' onclick="select_all()"/></th>
        <th>S. No</th>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Tamil</th>
        <th>English</th>
        <th>Computer</th>
        <th>Total</th>
      </tr>
      <tr>
        <td><input type='checkbox' class='case'/></td>
        <td>1.</td>
        <td><input type='text' id='first_name' name='first_name[]'/></td>
        <td><input type='text' id='last_name' name='last_name[]'/></td>
        <td><input type='text' id='tamil' name='tamil[]'/></td>
        <td><input type='text' id='english' name='english[]'/> </td>
        <td><input type='text' id='computer' name='computer[]'/></td>
        <td><input type='text' id='total' name='total[]'/> </td>
      </tr>
    </table>

    <button type="button" class='delete'>- Delete</button>
    <button type="button" class='addmore'>+ Add More</button>
    <p>
    <input type='submit' name='submit' value='submit' class='but'/></p>
</form>

Next need to include jquery...

<script src='jquery-1.9.1.min.js'></script>

Finally script which adds the table rows...

<script>
  var i=2;
  $(".addmore").on('click',function(){
    var data="<tr><td><input type='checkbox' class='case'/></td><td>"+i+".</td>";
        data +="<td><input type='text' id='first_name"+i+"' name='first_name[]'/></td> <td><input type='text' id='last_name"+i+"' name='last_name[]'/></td><td><input type='text' id='tamil"+i+"' name='tamil[]'/></td><td><input type='text' id='english"+i+"' name='english[]'/></td><td><input type='text' id='computer"+i+"' name='computer[]'/></td><td><input type='text' id='total"+i+"' name='total[]'/></td></tr>";
        $('table').append(data);
        i++;
});
</script>

Also refer demo & tutorial for this dynamically add & remove table rows

Change ID to class :

$("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');

$(".remCF").on('click',function(){
            $(this).parent().parent().remove();
        });

http://jsfiddle.net/7BHDm/1/

In addition to the other answers, I'd like to improve the removal, to something more generic:

$(this).closest('tr').remove();

This would be much better than using $(this).parent().parent().remove();, because it doesn't depend on the depth of the element. So, the structure of the row becomes much more flexible.

There are multiple problems here

Id should be unique in a page
For dynamic elements, you need to use event delegation using .on()

$(document).ready(function(){
    $("#addCF").click(function(){
        $("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" id="remCF">Remove</a></td></tr>');
    });

    $("#customFields").on('click', '#remCF', function(){
        $(this).parent().parent().remove();
    });

});

Demo: Fiddle

See this demo where id properties are removed.

$(document).ready(function(){
    $("#addCF").click(function(){
        $("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');
    });

    $("#customFields").on('click', '.remCF', function(){
        $(this).parent().parent().remove();
    });

});

Please try that:

<script>
$(document).ready(function(){
    var add = '<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td>';
                add+= '<input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" />&nbsp;&nbsp;&nbsp;';
                add+= '<input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" />&nbsp;';
                add+= '<a href="javascript:void(0);" class="remCF">Remove</a></td></tr>';

    $(".addCF").click(function(){ $("#customFields").append(add); });

    $("#customFields").on('click','.remCF',function(){
        var inx = $('.remCF').index(this);
        $('tr').eq(inx+1).remove();
    });
});
</script>

vary simple way you can solve it ..... take a look my new collected code.

 $(document).ready(function(){
            $(".add-row").click(function(){
                var name = $("#name").val();
                var email = $("#email").val();
                var markup = "<tr><td><input type='checkbox' name='record'></td><td>" + name + "</td><td>" + email + "</td></tr>";
                $("table tbody").append(markup);
            });

            // Find and remove selected table rows
            $(".delete-row").click(function(){
                $("table tbody").find('input[name="record"]').each(function(){
                    if($(this).is(":checked")){
                        $(this).parents("tr").remove();
                    }
