What would be the best way to dynamically add a set of rows to a table using JQuery?

I have a following table using MVC that shows number of items the user has.

 <table border = "1" id="tblItems">
            <%
                var itemnum = 1;
                foreach (var item in Model.Items)
            {%>

                <tr>
                    <td colspan="2" bgcolor="Silver"><strong>Item#<%=itemnum%></strong></td>
                    <td><%=Html.ActionLink("Delete", "DeleteItem", "Item", new { id = item.ID })%></td>

                </tr>
                <tr>
                    <td><strong>Name:</strong></td>
                    <td><%=Html.TextBox("ItemName_" + itemnum, item.Name)%></td>
                </tr>
                <tr>
                    <td><strong>Description:</strong></td>
                    <td><%=Html.TextBox("ItemDescription_" + itemnum, item.Description)%></td>
                </tr>


                <%itemnum++;
           } %>
        </table>

I will have a button that will Add New Item that will dynamically add identical structure.

Also, How would I assign a unique ID to each of the input controls? In my controller I need to loop through total number of items and get a value from each input control by Request.Form.Get("Name_" + i);

Any ideas on what is the best way to do this using JQuery?

Thanks for all the suggestions!

user(then a big number) :)

take a look at jqote (a jquery templating library). very small and can do exactly as you mention above. in fact, here's a small example doing just what you're after:

good luck - i've used it with great success.

You can use jQuery to duplicate the last row:

$("#tblItems tr:last").clone().appendTo("#tblItems");

But that will carry over your inputs with the same names as the last row, not a great out-of-the-box solution. You can add some extensive jQuery manipulation to re-name the inputs, or, as Dan Diplo pointed out, there are some jQuery extensions that can do this for you.

You can do this in raw jQuery using the .clone() method, but as Chris Pebble points out it doesn't rename your element names and Ids. However, there are a couple of jQuery plug-ins that help make this easy, so check out:

http://plugins.jquery.com/project/dupeIt

"dupeIt is a jquery plugin that allows you to duplicate and remove DOM elements and their children with one click. dupeIt smartly renames duplicated elements by appending the iteration number, ex. "txt_mytextfield" duplicate would be "txt_mytextfield2".

http://plugins.jquery.com/project/clonefield

"jQuery.cloneField is a plugin that provides you with easy, dynamic form field (or any other DOM element, really) duplication and removal."
