复制代码代码如下:function addCommas(nStr){nStr += '';x = nStr.split('.');x1 = x[0];x2 = x.length > 1 ? '.' + x[1] : '';var rgx = /(\d+)(\d{3})/;while (rgx.test(x1)) {x1 = x1.replace(rgx, '$1' + ',' + '$2');}return x1 + x2;}//数字格式化就可以变成var num = 123456.4231;num = num.toFixed(2);num =addCommas(num);// num = 123456.42
