不正确放置逗号

我有一个表格，每行都有一个文本输入。用户可以在每个文本框中指定一个美元金额。我的代码遍历每个文本输入并简单地总结这些值。我的问题是，当用户输入超过> = 1,000,000的值时，总和就会变得不正确。例如，当用户输入1,000,000时，总和为1,000。不正确放置逗号

function init_icheck() { 
    $('#datatable input[type=checkbox]').iCheck({ 
     checkboxClass: 'icheckbox_square-blue', 
     increaseArea: '10%' 
    }); 
} 

// When Pay in Full Checkbox is Checked fill in Pay This Time Field with Invoice Amount Due Value 
function paynow() { 
    var payFull = $('input[type="checkbox"].payfull'); 
    payFull.on('ifChecked', function(event) { 
     $(this).parents('tr').find('.paynow').val($(this).val().replace('$', '')); 
     CalcFooter(); 
    }); 
} 

// If Pay in Full Unchecked then remove value from respective Pay This Time Input 
// Only bind the ifUnchecked event if the checkbox is checked 
function remove_checkbox() { 
    var payFull = $('input[type="checkbox"].payfull'); 
    payFull.on('ifUnchecked', function(event) { 
     if ($(this).parents('tr').find('.paynow').val() == $(this).val().replace('$', '')) { 
      $(this).parents('tr').find('.paynow').val(''); 
      CalcFooter(); 
     } 
    }); 
} 

// If Pay This Time changes recalculate total 
function recalc_total() { 
    $('.paynow').keyup(function() { 
     var $ThisCheck = $(this).parents('tr').find('.payfull'); 
     // Add Commas if # is over 1,000 
     $(this).val(addCommas($(this).val().replace(/,/g, ''))); 
     if ($(this).val() == $ThisCheck.val().replace('$', '')) { 
      $ThisCheck.iCheck('check'); 
     } else { 
      $ThisCheck.iCheck('uncheck'); 
     } 
     CalcFooter(); 
    }); 
} 


// Recalc Function 
function CalcFooter() { 
    var amtPage = 0; 
    var amtTotal = 0; 

    var Sum = 0; 
    $('.paynow').each(function(index, Obj) { 
     var value = parseFloat($(this).val().replace(',', '')); 
     if (!isNaN(value)) amtPage += value; 
    }); 

    $('#datatable').DataTable().$('.paynow').each(function(index, Obj) { 
     var value = parseFloat($(this).val().replace(',', '')); 
     if (!isNaN(value)) amtTotal += value; 
    }); 

    $('#amounttopay').text(
     'Page: $' + addCommas(amtPage.toFixed(2)) + 
     '/Total: $' + addCommas(amtTotal.toFixed(2)) 
    ); 
} 

// Add Commas if value > 1,000 
addCommas = function(input) { 
    // If the regex doesn't match, `replace` returns the string unmodified 
    return (input.toString()).replace(
     // Each parentheses group (or 'capture') in this regex becomes an argument 
     // to the function; in this case, every argument after 'match' 
     /^([-+]?)(0?)(\d+)(.?)(\d+)$/g, 
     function(match, sign, zeros, before, decimal, after) { 
      // Less obtrusive than adding 'reverse' method on all strings 
      var reverseString = function(string) { 
       return string.split('').reverse().join(''); 
      }; 
      // Insert commas every three characters from the right 
      var insertCommas = function(string) { 
       // Reverse, because it's easier to do things from the left 
       var reversed = reverseString(string); 
       // Add commas every three characters 
       var reversedWithCommas = reversed.match(/.{1,3}/g).join(','); 
       // Reverse again (back to normal) 
       return reverseString(reversedWithCommas); 
      }; 
      // If there was no decimal, the last capture grabs the final digit, so 
      // we have to put it back together with the 'before' substring 
      return sign + (decimal ? insertCommas(before) + decimal + after : insertCommas(before + after)); 
     } 
    ); 
}; 

// Reinitialize iCheck on Pagination Change 
$('#datatable').on('draw.dt', function() { 
    init_icheck(); 
    paynow(); 
    recalc_total(); 
    remove_checkbox(); 
    CalcFooter(); 
}); 

// Initialize Datatables 
$('#datatable').dataTable({ 
    "stateSave": true, 
    "oLanguage": { 
     "sSearch": "Search Results:" 
    } 
});

我有一个简单的jsfiddle来说明这个问题。我提前感谢你指引我朝着正确的方向前进。
