Actionscript解析货币以获得数字

Question

我使用CurrencyFormatter将2个数字解析为其货币表示

currencyFormat.format（“10”+“。”+“99”）---＆gt; $ 10.99

我很好奇是否有办法将字符串“$ 10.99”解析回数字/ double？ 所以可以得到小数点左侧和小数点右侧的值。

感谢，

你可以通过多种方式做到这一点。这是我头顶的两个：

function currencyToNumbers($currency:String):Object {
    var currencyRE:RegExp = /\$([1-9][0-9]+)\.?([0-9]{2})?/;
    var val = currencyRE.exec($currency);
    return {dollars:val[1], cents:val[2]};
}


function currencyToNumbers2($currency:String):Object {
    var dollarSignIndex:int = $currency.indexOf('$');
    if (dollarSignIndex != -1) {
        $currency = $currency.substr(dollarSignIndex + 1);
    }
    var currencyParts = parseFloat($currency).toString().split(".");
    return {dollars:currencyParts[0], cents:currencyParts[1]};
}

var currency:Object = currencyToNumbers('$199.99');
trace(currency.dollars);
trace(currency.cents);

var currency2:Object = currencyToNumbers2('$199.99');
trace(currency2.dollars);
trace(currency2.cents);
