jQuery – on（'click'）追加似乎无效

Question

http://jsfiddle.net/D6be5/

HTML

<table class="example" border="1">
    <tr>
        <td>
            <label>Enter text</label>
            <textarea>Enter text</textarea>
        </td>
    </tr>
    <tr class="clone"></tr>
</table>

<p><button id="add-row">Add Row</button></p>​

jQuery

$(document).ready(function() {
    $(this).on('click', function(event) {
        if ( ! $(event.target).closest('table').hasClass('example')) {
            $('table label').show();
            $('table textarea').hide();
        }
    });

    $('table td').on('click', function() {
        $('table label').show();
        $('table textarea').hide();
        $(this).find('label').hide();
        $(this).find('textarea').show();
    });

    $('#add-row').on('click', function() {
        _this = $('table tr.clone')
            .clone()
            .removeClass('clone')
            .insertBefore('.clone');

        _this.append('<td><label>Enter text</label><textarea>Enter text</textarea></td>');
    });                
});​

CSS

table textarea {
    display: none;
}

table .clone {
    display: none;
}​

The link above explains what I'm trying to do.

Basically the problem is this. I have a label and textarea within a td , the textarea is hidden and only the labels show at start. When the user clicks on the cell of the table it hides the label and shows the textarea , which works fine until you try and add a clone of the row then it doesn't do anything.

Edit : Forgot to mention why I'm cloning the row and adding the cells afterwards. In my actual code I allow for column creation as well and I do a count of the rows and add the cells after.

Thank you very much for any help =)

Answer 1

Another Method.

$('table').on('click', "td", function() {

})

Answer 2

Change the click handler to

$(document).on('click', 'table td', function() {
//Your code
}

Answer 3

You may want to try using the .on() method on your $('table td').click() event:

$('table td').on('click', function() {
    $('table label').show();
    $('table textarea').hide();
    $(this).find('label').hide();
    $(this).find('textarea').show();
});

Hope that helps
