Format as currency in Javascript
提问by Liam
I have a variable which is made up of a multiplication of 2 more variables
我有一个变量，它由 2 个以上变量的乘积组成
var EstimatedTotal = GetNumeric(ServiceLevel) * GetNumeric(EstimatedCoreHours);
Is it possible, and if so how, or what is the function called to format this as currency? I've been googling only I cant find a function and the only ways I've seen are really, really long winded
是否可能，如果可能，如何或调用什么函数将其格式化为货币？我一直在谷歌搜索，只是我找不到一个功能，我看到的唯一方法真的非常冗长

Taken from here: http://javascript.internet.com/forms/currency-format.html. I've used it and it works well.
取自此处：http: //javascript.internet.com/forms/currency-format.html。我已经使用过它并且效果很好。
function formatCurrency(num)
{
num = num.toString().replace(/$|\,/g, '');
if (isNaN(num))
{
num = "0";
}
sign = (num == (num = Math.abs(num)));
num = Math.floor(num * 100 + 0.50000000001);
cents = num % 100;
num = Math.floor(num / 100).toString();
if (cents < 10)
{
cents = "0" + cents;
}
for (var i = 0; i < Math.floor((num.length - (1 + i)) / 3); i++)
{
num = num.substring(0, num.length - (4 * i + 3)) + ',' + num.substring(num.length - (4 * i + 3));
}
return (((sign) ? '' : '-') + '$' + num + '.' + cents);
}

If you are looking for a quick function which would format your number (for example: 1234.5678) to something like: $1234.57 you may use .toFixed(..) method:
如果您正在寻找一个快速函数，它将您的号码（例如：1234.5678）格式化为类似：$1234.57，您可以使用 .toFixed(..) 方法：
EstimatedTotal = "$" + EstimatedTotal.toFixed(2);
The toFixed function takes an integer value as the argument which means the number of trailing decimals. More information about this method can be found at http://www.w3schools.com/jsref/jsref_tofixed.asp.
toFixed 函数将一个整数值作为参数，这意味着尾随小数的数量。有关此方法的更多信息，请访问 http://www.w3schools.com/jsref/jsref_tofixed.asp。
Otherwise, if you would like to have your output format as: $1,234.57 you need to implement your own function for this. Below are two links with implementation:
否则，如果您希望输出格式为：$1,234.57，您需要为此实现您自己的函数。以下是两个与实现的链接：

May not be perfect, but works for me.
可能不完美，但对我有用。
if (String.prototype.ToCurrencyFormat == null)
String.prototype.ToCurrencyFormat = function()
{
if (isNaN(this * 1) == false)
return "$" + (this * 1).toFixed(2);
}

There are no in-built functions for formatting currency in Javascript.
在 Javascript 中没有用于格式化货币的内置函数。
There are a number of scripts that you can find online that will help you with writing your own, however, here's one:
您可以在网上找到许多脚本来帮助您编写自己的脚本，但是，这里有一个：
