I am using jQuery. How to enable or disable textbox inside a table when checkbox checked. This is my edit.cshtml.

   <table id="scDetails" class="dataTable">
            <thead>
                <tr>
                    <th>RItem</th>
                    <th>IChecked</th>
                    <th>Notes</th>
                </tr>
            </thead>
            <tbody>
                @foreach (var fback in Model.Fbacks)
                {
                    <tr>
                        <td @Html.DisplayFor(m => fback.RItem)</td>
                        <td>@Html.CheckBoxFor(m => fback.IChecked)</td>
                        <td>@Html.TextBoxFor(m => fback.Notes)</td>
                    </tr>
                }
            </tbody>
        </table>

What i have tried is:

 $('td :checkbox').change(function () {
            var parentTx = $(this).closest('tr').find(input[type = "text"]);
            if (this.checked) {
                parentTx.attr("disabled",false);
            } else {
                parentTx.attr("disabled", true);
            }
        });

Where am doing wrong? I dont want to use any classes on the controls to achieve this.

You missed the quotes, and you could simply your code with:

$('td input[type="checkbox"]').change(function () {
  $(this).closest('tr').find('input[type="text"]').prop('disabled', !this.checked);
}).change();
