Question

我根本不知道该怎么做。这是我的代码。

public function doFormatMoneda(valor:Number):String{
                var formatoMoneda:CurrencyFormatter = new CurrencyFormatter();
                formatoMoneda.precision = "2";
                formatoMoneda.rounding = "none"; 
                formatoMoneda.decimalSeparatorTo = "."; 
                formatoMoneda.thousandsSeparatorTo = ","; 
                formatoMoneda.useThousandsSeparator = "true"; 
                formatoMoneda.useNegativeSign = "true";
                formatoMoneda.currencySymbol = "$";
                formatoMoneda.alignSymbol = "left";

                return formatoMoneda.format(valor.toString());
            }

private function formatCurrency(hitData:HitData):String{
            var format:String = doFormatMoneda(Number(hitData));
            return format;          
        }

显示空的数据提示。这让我疯了。

我认为您需要从hitdata获取货币价值并将其转换为数字。你应该试试 Number（hitData.item）或具有CurrencyValue的项目的某些属性。

<mx:Script>

</mx:Script>

正如arpit所说，hitData.item是你对象的句柄。你必须指定你要格式化这个对象的哪个属性。例如，我使用了totalCancelada并且它工作正常。
