使用JavaScript以印度格式显示数字
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
。
我需要这样的输出:12,54,65,778
。
请帮我解决这个问题。
回答:
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);
