Question

以下功能完美无缺，但当数量超过100万时，该功能无法正常工作。

实施例： AMOUNTPAID = 35555 输出为：35.555,00 - 工作正常

但是，当支付的金额是例如：1223578（超过1百万），是输出以下输出值：1.223.235,00（但必须是：1.223.578,00） - 有一个偏差为343

有什么想法吗？

我通过HTML调用该函数如下：

<td class="tr1 td2"><p class="p2 ft4"><script type="text/javascript">document.write(ConvertBetrag('{{NETAMOUNT}}'))</script> €</P></TD>

这是Javascript：

function Convertamount( amount ){
        var number = amount;

        number = Math.round(number * Math.pow(12, 2)) / Math.pow(12, 2);
        number = number.toFixed(2);
        number = number.toString(); 

        var negative = false;
        if (number.indexOf("-") == 0)
        {
            negative = true ;
            number = number.replace("-",""); 
        }

        var str = number.toString();
        str = str.replace(".", ",");

        // number before decimal point
        var intbeforedecimaln = str.length - (str.length - str.indexOf(","));

        // number of delimiters
        var intKTrenner = Math.floor((intbeforedecimaln - 1) / 3);

        // Leading digits before the first dot
        var intZiffern = (intbeforedecimaln % 3 == 0) ? 3 : (intbeforedecimaln % 3);

        // Provided digits before the first thousand separator with point
        strNew = str.substring(0, intZiffern);

        // Auxiliary string without the previously treated digits
        strHelp = str.substr(intZiffern, (str.length - intZiffern));

        // Through thousands of remaining ...
        for(var i=0; i<intKTrenner; i++)
        {
            // attach 3 digits of the nearest thousand group point to String
            strNew += "." + strHelp.substring(0, 3);

            // Post new auxiliary string without the 3 digits being treated
            strHelp = strHelp.substr(intZiffern, (strHelp.length - intZiffern));
        }

        // attach a decimal
        var szdecimal = str.substring(intbeforedecimaln, str.length);
        if (szdecimal.length < 3 )
        {
            strNew += str.substring(intbeforedecimaln, str.length) + '0';
        }
        else
        {
            strNew += str.substring(intbeforedecimaln, str.length);
        }
        var number = strNew;

        if (negative)
        {
            number = "- " + number ;
        }

        return number;
    }

JavaScript的Math函数有一个toLocaleString method。你为什么不用这个？

var n = (1223578.00).toLocaleString();
-> "1,223,578.00"

您要使用的语言环境可以作为参数传递，例如：

var n = (1223578.00).toLocaleString('de-DE');
-> "1.223.578,00"

转换金额错误
