Javascript计算器-逗号问题

Question

I am very new to Javascript; as in about 3 days new... I am working on creating a calculator to extract data from three input fields and then calculates out to a rough monthly and yearly total. It then uses this total to dynamically build out a table.

For the most part I have everything working, with one exception. If someone types a comma into the input fields it will only recognize the value before the comma. So for example if they type 10,000; it will read it as 10. I've tried to place in a Regex based replace, but it doesn't seem to be working. I may be placing it in the wrong place, but I tried it a few different ways, so now sure.

Below is the portion of the code that I am having trouble with.

    <input onblur="findTotal();" type="text" name="qty" id="qty1"/>
    <input onblur="findTotal();" type="text" name="qty" id="qty2"/>
    <input onblur="findTotal()" type="text" name="qty" id="qty3"/>

    <input disabled type="text" name="totalyr" id="totalyr"/>
    <input disabled type="text" name="totalmo" id="totalmo"/>

    <script type="text/javascript">
    function findTotal(){
        var getqty = document.getElementsByName('qty');
        var tot=0;
        for(var i=0;i<getqty.length;i++){
            if(parseInt(getqty[i].value))
                (tot += parseInt(getqty[i].value));
        }
        document.getElementById('totalmo').value = tot*4;
        document.getElementById('totalyr').value = tot*52;
    }
    </script>

I've tried making the inputs numbers as well, but that did nothing.

Any advice would be greatly appreciated!

Had this yesterday, this is what worked for me

    var getqty = document.getElementsByName('qty').value.replace(/,/g, "");

alternatively something like

    var getqty = +document.getElementByName("qty").value.replace(/[^\de.-]/gi, "");
