Question

我不是关于regex的专家,我需要一些帮助来编排数字格式。

这就是我所拥有的:

TheNumber = TheNumber.toString().split(/(?=(?:d{3})+(?:.|$))/g).join(",");

基本上,我要用逗号格式化《数字》格式化,将千分之3小数精确度与点相分离,如果是小数,则用点表示小数。它也应该使用负数。

此刻,我并不远只处于此

3234234.223512 becomes 3,234,234.223,512

谢谢你的帮助

Answer 1

我找到了这个 Javascript 库< a href=""http://josscrowcroft.github.com/count.js/#download" rel="nofollow" count.js

As mentioned in description.
Accounting.js is a tiny JavaScript library for number, money and currency formatting, with optional excel-style column rendering (to line up symbols and decimals). It s lightweight, fully localisable and has zero dependencies.

它和你的要求一样,甚至更多一些。

Answer 2

d 用两块而不是一个正则表达式来解决这个问题。

remove the decimal point and any following numbers from the string first
User your reg exp (minus the decimal part) to add commas to the first part
concatenate back the removed decimal point
