如何在javascript或jquery中设置千位分隔符 [英] How to set thousand separator in javascript or jquery

问题描述

我有号码，我必须申请一千个分隔符



ex如果我的号码



double num = 123454545.125871656



结果应该像



123,454,545.125871656



我的尝试：



num.toString（）。replace（/ \B（ ？=（\d {3}）+（？！\d））/ g，，）;



结果如果有纯正的话会变得正确整数值，如12345789



12,345,789



但是当我得到双倍价值时如123454545.125871656

i得到123,454,545.125,871,656 ---->这个worng

i have number for which i have to apply a thousand separator

ex if my number

double num = 123454545.125871656

the result should be like

123,454,545.125871656

What I have tried:

num.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");

the result getting correct if have pure integer value like 12345789

12,345,789

but when i get double value like 123454545.125871656
i am getting 123,454,545.125,871,656 ---->this worng

推荐答案

你可以先取小数部分，正则表达整数部分，然后把它们放进去再次一起。

You can take out the decimal part first, regex the integer part, then put them together again.
