 s = s.TrimEnd(",".ToCharArray());

Answer 2

Using substring

var strNumber = "3623,3635,";

document.write(strNumber.substring(0, strNumber.length - 1));

Using slice

document.write("3623,3635,".slice(0, -1));

Using map

var strNumber = "3623,3635,";

var arrData = strNumber.split(',');

document.write($.map(arrData, function(value, i) {
  return value != "" ? value : null;
}).join(','));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Use Array.join

var strNumber = "3623,3635,";
var arrTemp = strNumber.split(',');
var arrData = [];

$.each(arrTemp, function(key, value) {
  //document.writeln(value);
  if (value != "")
    arrData.push(value);
});

document.write(arrData.join(', '));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

    strclean = $.trim(str.replace(/#/g, ''));

Answer 6

Use Array.join

var s = "";
n.each(function() {
    s += $(this).val() + ",";
});

becomes:

var a = [];
n.each(function() {
    a.push($(this).val());
});
var s = a.join(', ');
