1.最简单的内置format函数: >>> format(1234567890,',') '1,234,567,890' 2.正则表达式: import re def formatNum(num): num=str(num) pattern=r'(\d+)(\d{3})((,\d{3})*)' while True: num,count=re.subn(pattern,r'\1,\2\3',num) if count==0: break return num if __name__=='
js脚本function: //js数字千分符处理 function commafy(num) { num = num + ""; var re = /(-?\d+)(\d{3})/ while (re.test(num)) { num = num.replace(re, "$1,$2") } return num; }
//js数字千分符处理 function commafy(num) { num = num + ""; var re = /(-?\d+)(\d{3})/ while (re.test(num)) { num = num.replace(re, "$1,$2") } return num; } 执行下,效果不错,收藏记录
一般在JavaScript中实现千分符,是使用切割+连接一顿操作 这里尝试一下使用正则快速实现千分符 let num0 = '12' let num1 = '123' let num2 = '1234' let num3 = '123456789' let num4 = '1234567890' let num5 = '12345678901' let num6 = '123456789012' let num7 = '1234567890123' let r0 = num0.replace(/
