我的表单看起来像这样：

<table id="productTable" class="table table-striped table-condensed">
     <thead>
        <tr>
         <th>Product</th>
         <th>Datum</th>
         <th>Tijd</th>
         <th>Minuten</th>
        </tr>
     </thead>
    <tbody>   
     <tr>
        <td><input id="products" class="input-medium" name="products[]" type="text" /></td>
        <td><input id="date" class="datepick input-mini" name="date[]" type="text" /></td>
        <td><input id="time" class="input-mini" name="time[]" type="text" /></td>
        <td><input id="minutes" class="input-mini" name="minutes[]" type="text" /></td>
        <td><a id="addnew" href=""><i class="icon-plus"></i></a></td>
      </tr>
    </tbody>
</table>

我有的jquery,看起来像这样：

$(function(){
        // start a counter for new row IDs
        // by setting it to the number
        // of existing rows
        $('.datepick').datepicker();

        var newRowNum = 0;

        // bind a click event to the "Add" link
        $('#addnew').click(function(){
            // increment the counter
            newRowNum = $(productTable).children('tbody').children('tr').length +1;

            // get the entire "Add" row --
            // "this" refers to the clicked element
            // and "parent" moves the selection up
            // to the parent node in the DOM
            var addRow = $(this).parent().parent();

            // copy the entire row from the DOM
            // with "clone"
            var newRow = addRow.clone();

            // set the values of the inputs
            // in the "Add" row to empty strings
            $('input',addRow).val('');

            // insert a remove link in the last cell
            $('td:last-child',newRow).html('<a href="" class="remove"><i class="icon-minus"><\/i><\/a>');

            // insert the new row into the table
            // "before" the Add row
            addRow.before(newRow);

            // add the remove function to the new row
            $('a.remove',newRow).click(function(){
                $(this).closest('tr').remove();
                return false;               
            });

            $('#date',newRow).each(function(i){
                var newID = 'date_' + i;
                $(this).attr('id',newID);
            });

            // prevent the default click
            return false;
        });
