Question

I have been trying to use nextAll() and siblings() but those functions never return anything and I can only presume that it has to do with the form inputs being nested in other html elements (table cells).

// This works like I would expect but obviously returns all the input elements
$("input.tbDate").each( function(index) {
    alert('class selector : Index=' + index + ' id=' +  $(this).attr("id") );
});

// these next ones do not work, I only need elements after currently selected input
$(obj).siblings().each( function(index) {
    alert('sibings() : Index=' + index + ' id=' +  $(this).attr("id") );
});

$(obj).nextAll().each( function(index) {
    alert('nextAll() : Index=' + index + ' id=' +  $(this).attr("id") );
});

So I want to get all of the sibling elements that are after the currently selected element

UPDATE :
So this would work in my specific situation – see answer below
$(this).parent().parent().nextAll().find('input')...

But this is what I had already done to get my page working

$("input.tbDate").each( function(index) {
    if (endDate != null) 
    {
        if ( $(this).attr("id").indexOf("StartDate") != -1 )
        {
            endDate.setDate( endDate.getDate() + 1);
            var dayOfTheWeek = endDate.getDay();
            if (dayOfTheWeek==6)
            {
                endDate.setDate(endDate.getDate()+2);
            }
            else if (dayOfTheWeek==0)
            {
                endDate.setDate(endDate.getDate()+1);
            } 
        }
        endDateString = endDate.getMonth() + 1 + "/" +  endDate.getDate() + "/" +  endDate.getFullYear();
        $(this).val( endDateString );
    }
    // Found input text box and grabbing
    if ( $(this).attr("id") ==  $(obj).attr("id"))
    {
        endDate = new Date( $(obj).val() );
    } 
});

Is there a gotcha doing it the way I did it? Is one way of selecting elements preferred (faster/better) than another?

If the inputs are inside <td> wrappers you’d need to first grab the parent <td> then grab all the next sibling <td>‘s and traverse into them:

$('input.tbDate').parent().nextAll().find('input').css('border','3px solid red');

Try that to put a border around the elements you seek and you’ll know if JQuery is acknowledging them.

Test case HTML:

<table>
    <tr>
        <td>
            <input type="text" class="test" />
            <input type="text" class="test" />
            <input type="text" class="test" />
        </td>
        <td>
            <input type="text" class="test" />
            <input type="text" class="test" />
            <input type="text" class="test" />
        </td>
        <td>
            <input type="text" class="test" />
            <input type="text" class="test" />
            <input type="text" class="test" />
        </td>
    </tr>
</table>

Test case CSS:

.red {
    border:2px solid red;
}

Test case JQuery:

$(function(){
    $('.test').click(function(){
        $('.test').removeClass('red');
        $(this).nextAll().addClass('red');
        $(this).parent().nextAll().find('input').addClass('red');
    }); 
});
