用于 Flash 的 AS3 flash 货币格式化程序

Question

我需要帮助来扩展正确的字符串？将我的数字步进器和/或文本显示字段格式化为货币格式。您可以从此处的 CS5 flash FLA 下载 FLA。谢谢

嘿，我希望这会有所帮助，

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

该函数非常简单，我们调用函数 formatCost()

如果您只想将其格式化为 0 位小数，formatCost(value as string,0)< /代码>
如果您需要货币，请将其添加为第三个参数。
如果您需要符号出现在数字后面，请将位置设置为 1
所以...

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

如果需要，您可以在公式中添加更多内容，以便第 5 个变量可以是间隔符，这样您就可以将其从“，”更改为“。” （法语）或作为空格“”

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

货币格式化的更好替代方法是使用 Adob​​e 类 flash.globalization.CurrencyFormatter

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

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

    }

该类非常灵活，允许您自定义区域设置的货币外观。

问题是您没有注意变量类型。

this.payrollOut - 是一个文本字段

this.payrollOut.text - 是该文本字段中包含的文本

this.payroll.value 不能分配文本字段或文本值

因此您必须转换为它期望的类型 - 在本例是一个数字。

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

cf.format 也需要一个数字值，并将返回一个字符串。

一个使用示例可能是：

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

我看到的代码还有其他问题 - payrollOut 没有价值 - 因此它仍然无法按预期运行，但这解决了眼前的问题。
