Question

I have the following question.

I have a table, like the example below. The plan is to copy a row but not with a new class. The class should change in a remove class. Example in jsfiddle: http://jsfiddle.net/klaas3/wgRYR/ The goal is to keep the last row always green and the others red.

<table class="test">
<thead>
    <tr>
        <td>header 1</td>
        <td>header 2</td>
        <td>header 3</td>
        <td>header 4</td>
    </tr>
</thead>
<tbody>
    <tr class="1">
        <td>data 1</td>
        <td>data 2</td>
        <td>data 3</td>
        <td class="remove"></td>
    </tr>
    <tr class="2">
        <td>data 1</td>
        <td>data 2</td>
        <td>data 3</td>
        <td class="remove"></td>
    </tr>
    <tr class="new">
        <td>data 1</td>
        <td>data 2</td>
        <td>data 3</td>
        <td class="new"></td>
    </tr>
</tbody>

I use the last column(with the new and remove class or red and green colors) as a button.

I have the following allready, but something seems to go wrong:

$("table.test tr.new:last td.new").click(function(){
$('table.test tr.new:last  td.new').removeClass('new').addClass('remove').fadeIn("fast");
$('table.test tr.new:last').clone(true).insertAfter('table.test tr.new:last');
});

Mind you, I am not a very experienced jquery user. Also when the cell class is changed I will change the table row class as well with a db id. (But that I will try myself with a working sample).

EDIT:

You need to clone the element before changing the classes

Also to turn off/remove the click event handler use .off()

$("table.test tr.new:last td.new").click(function(){
    var x = $('table.test tr.new:last').clone(true);
    // you can use "this" instead of $('table.test tr.new:last  td.new') since you are inside it's event handler
    $(this).removeClass('new').addClass('remove').off('click');// <-- removes handler from current td 
    x.insertAfter('table.test tr.new:last');
});​
