適用於Flash的AS3 Flash CurrencyFormatter

Question

我需要擴展適當字符串的幫助嗎？ 將我的數字步進器和/或文本顯示字段格式化為貨幣格式。 您可以從CS5 Flash FLA HERE下載FLA 。 謝謝

嘿，我希望這會有所幫助，

myTextField1.text = formatCost(String(4813.134),2,"$",0);// result: $ 4,813.13

該函數非常簡單，我們將其formatCost()函數。

如果只想將其格式化為0 formatCost(value as string,0) ，請使用formatCost(value as string,0)
如果您需要貨幣，則將其添加為第三個參數。
如果需要在數字后面顯示符號，請將位置設置為1
所以...

formatCost(String(8/35*100),1,"%",1);// will give "22.9 %"

如果需要，您可以進一步增加公式，以便第5個變量可以是分隔符，以便可以將其從“，”更改為“”。 （對於法語）或空格“”

public function formatCost(v:String, 
           decimal_places:int = 2, 
           currency_symbol:String = "", 
           placement:int = 0){
        v = String(Number(v).toFixed(decimal_places));
        var result:String = new String();
        if(decimal_places == 0){
        }else{
            result = v.substr(-1-decimal_places);
            v = v.substr(0, v.length-1-decimal_places);
        }
        while( v.length > 3 ){
            result = "," + v.substr(-3) + result;
            v = v.substr(0, v.length-3);
        }
        if(v.length > 0){
            if(placement == 0){
                result = currency_symbol + " " + v + result;
            }else if(placement == 1){
                result = v + result + " " + currency_symbol;
            }else{
                result = v + result;
            }
        }
        return result;
    }//closes formatCost

貨幣格式的一種更好的替代方法是使用Adobe類flash.globalization.CurrencyFormatter

public static function getDollars(value:Number):String{

        var targetFormatter:CurrencyFormatter = new CurrencyFormatter("en-US");
        return targetFormatter.format(value, true);

    }

此類非常靈活，可讓您自定義語言環境的貨幣外觀。

問題是您沒有注意變量類型。

this.payrollOut-是一個文本字段

this.payrollOut.text-是該文本字段中包含的文本

無法為this.payroll.value分配文本字段或文本值

因此，您必須將其轉換為期望的類型-在這種情況下為數字。

this.payroll.value = Number(this.payrollOut.text);

cf.format也需要Number值，並且將返回String。

用法示例可能是：

var payrollAmount:Number = 400;
var payrollCurrencyAmount:String = cf.format(payrollAmount);

我看到的代碼還有其他問題-payrollOut沒有價值-因此它仍然無法按預期運行，但這解決了緊迫的問題。
