Question

I am working on dynamically allowing a user to add or remove table rows which contain form fields.

there are two main issues I am having- which entail being able to use a selector to capture the second element of a table (in hopes of ignoring the header row)

and second working with jQuery and the disabled attribute. When calling it initially I cannot change the attribute there after with a js if statement.

my code is here for review: http://jsfiddle.net/Jcortes/BE5Lr/792/

If anyone could help it’d be appreciated.

$(document).ready(function() {
$('#DelBtn').attr('disabled', 'disabled');
var count = 1;
//*******************************************************************    
$('#AddBtn').click(function() {
    //problem is below, the selector is not returning the other elements. (ex=second)
    $("table tr:first").clone().find("input").each(function() {
        $(this).val('').attr('id', function(_, id) {
            return id + count;
        });
    }).end().appendTo("table");
    count++;
    if (count == 2) {
        $('#DelBtn').attr('disabled', '');
    }        
    if (count == 5) {
        $('#AddBtn').attr('disabled', 'disabled');
    }
}); //end AddBtn Function
//*******************************************************************    
$('#DelBtn').click(function() {
    $("table tr:last").remove();
    count--;
    if (count == 1) {
        $('#DelBtn').attr('disabled', 'disabled');
        $('#AddBtn').attr('disabled', '');
    }
}); //end DelBtn Function
//*******************************************************************    
}); //end DOM Ready

The reason the attr('disabled', '') call fails i because you are using jQuery 1.7. jquery 1.7 now properly differentiates between attributes and properties. Disabled is a property. Use the .prop() method instead.

$('selector').prop('disabled', 'disabled');
$('selector').prop('disabled', '');

Ah, I see second problem now. You can use nth-child selector to get second row.

$('table tr:nth-child(2)').clone();
