Question

I want after remove one of the rows (Ex: Row 2) in html code changed to in name element by jQuery.

For example we first have in html as:

Row 1: name=”check[0][]”
Row 2(removed): name=”check[1][]”
Row 3: name=”check[2][]”
Row 4: name=”check[3][]”

Now if we remove the second row, In fact, after removed the row 2, we have rows like this:

Row 1: name=”check[0][]”
Row 3: name=”check[2][]”
Row 4: name=”check[3][]”

But i want it in result (after remove one of rows ex: row 2) as:

Row 1: name=”check[0][]”
Row 3: name=”check[1][]”
Row 4: name=”check[2][]”

I tried as (see my full code) but Don’t work: http://jsfiddle.net/k3wne/

Js:

$('.remove_input').live('click', function (e) {
    e.preventDefault();
    var remove = $(this).closest($class);
    remove.fadeOut('slow', function () {
        $('.add_units').each(function (idx, val) {
            var num = $('.add_units').length;
            NumIdx = (num - (num - idx));
            //for(var i = 0; i < num-1; i++){
            $(this).closest($class_guide).next($class_guide).each(function (idx, val) {
                $('.add_units input[type="checkbox"]').attr('name', function (idx, str) {
                    var int = parseInt(str.match(/\d+/)[0], 10);
                    return str.replace(int, NumIdx);
                })
            });
            //}
        })
    });)
}​

DEMO

$('.remove_input').live('click', function (e) {
    e.preventDefault();
    var remove = $(this).closest('.RowCheck');
    remove.fadeOut('slow', function () {
        $(this).remove(); // or change next line to  $('.RowCheck:visible')
        $('.RowCheck').each(function (idx) {
            var checkBoxes = $('input[type="checkbox"]',this);
            checkBoxes.each(function(i) {
              var str = $(this).attr('name');  
              var currentIdx = parseInt(str.match(/\d+/)[0], 10);  
              $(this).attr('name', str.replace(currentIdx,idx));
           })
        });
    });
});​

This code will work if you either

1. remove the row for real – also suggested by Explosion Pills or
2. test for visible like Simon did
