我在印度编号系统中显示以下代码。
var x=125465778; var res= x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
正在获取此输出:125,465,778。
125,465,778
我需要这样的输出:12,54,65,778。
12,54,65,778
请帮我解决这个问题。
对于整数:
var x=12345678; x=x.toString(); var lastThree = x.substring(x.length-3); var otherNumbers = x.substring(0,x.length-3); if(otherNumbers != '') lastThree = ',' + lastThree; var res = otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree; alert(res);
对于浮点数:
var x=12345652457.557; x=x.toString(); var afterPoint = ''; if(x.indexOf('.') > 0) afterPoint = x.substring(x.indexOf('.'),x.length); x = Math.floor(x); x=x.toString(); var lastThree = x.substring(x.length-3); var otherNumbers = x.substring(0,x.length-3); if(otherNumbers != '') lastThree = ',' + lastThree; var res = otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree + afterPoint; alert(res);
