Delete Table Row Except in First Row

Question

I have a form which allows the user to add a new table row via a button in the bottom row which all is working well. I now need to also add the functionality to have an additional button to allow them to delete a table row.

I gather the simplest method would be to use:

$(this).closest('tr').remove();

but I'm having trouble integrating this into the existing functionality. I also only need the "delete" button to appear on all rows except the first row (i.e. users can delete all rows except the first one). I've setup a jsfiddle here that demonstrates my current functionality:

http://jsfiddle.net/fmdataweb/daayf/1/

So in my example when the user clicks the "Add another activity" button it should create the new table row as it currently does but also add the "delete" button which deletes that row. I've currently hard-coded the "delete" button to the first row as I'm now sure how to make it appear only for new rows created via the "add new activity" button.

Answer 1

Few changes

In the starting markup, add the classes addbtn and delbtn also hide the delete button

<td>
    <input type="button" class="button mt5 addbtn" value="Add another activity" id="button1" name="button2" />
</td>
<td>
    <input type="button" class="button mt5 delbtn" value="Delete" id="deleteRowButton" name="deleteRowButton" style="display: none"/>
</td>

Then

$('#lastYear').on('click', '.delbtn', function () {
    $(this).closest('tr').remove()
});

var newIDSuffix = 2;
$('#lastYear').on('click', '.addbtn', function () {
    var thisRow = $(this).closest('tr')[0];
    $(thisRow).find('.delbtn').show();

    var cloned = $(thisRow).clone();
    cloned.find('input, select').each(function () {
        var id = $(this).attr('id');
        id = id.substring(0, id.length - 1) + newIDSuffix;
        $(this).attr('id', id);
    });

    cloned.insertAfter(thisRow).find('input:text').val('');
    cloned.find('.delbtn').hide();
    cloned.find("[id^=lastYearSelect]")
    .autocomplete({
        source: availableTags,
        select: function (e, ui) {

            $(e.target).val(ui.item.value);
            setDropDown.call($(e.target));
        }
    }).change(setDropDown);

    $(this).remove();
    newIDSuffix++;
});
