使用JavaScript以印度格式显示数字

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);
