jquery sum of multiple input fields if same class in one input

Hello I need to sum the values of same class input in one input with class name total.

<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />

<input type="text" class="total" value="" />

Possible?

A working fiddle here

$(document).on("change", "qty1", function() {
    var sum = 0;
    $("input[class *= 'qty1']").each(function(){
        sum += +$(this).val();
    });
    $(".total").val(sum);
});

Answer

You pretty much had it, just needed to adjust your JQuery a little bit for the appropriate selectors

updated fiddle : http://jsfiddle.net/5gsBV/7/

$(document).on("change", ".qty1", function() {
    var sum = 0;
    $(".qty1").each(function(){
        sum += +$(this).val();
    });
    $(".total").val(sum);
});
