如何将数字格式化为货币字符串 [英] How to format numbers as currency strings

问题描述

我想用JavaScript格式化价格.我想要一个以 float 作为参数并返回格式如下的 string 的函数:

I would like to format a price in JavaScript. I'd like a function which takes a float as an argument and returns a string formatted like this:

"$ 2,500.00"

做到这一点的最佳方法是什么?

What's the best way to do this?

推荐答案

好吧，根据您的说法，我正在使用此代码:

Ok, based on what you said, I'm using this:

var DecimalSeparator = Number("1.2").toLocaleString().substr(1,1);

var AmountWithCommas = Amount.toLocaleString();
var arParts = String(AmountWithCommas).split(DecimalSeparator);
var intPart = arParts[0];
var decPart = (arParts.length > 1 ? arParts[1] : '');
decPart = (decPart + '00').substr(0,2);

return '£ ' + intPart + DecimalSeparator + decPart;

我愿意接受改进建议(我不希望不包含 YUI 就是这样做:-))

I'm open to improvement suggestions (I'd prefer not to include YUI just to do this :-) )

我已经知道我应该检测到.".而不只是将其用作小数点分隔符...

I already know I should be detecting the "." instead of just using it as the decimal separator...
