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,$2") } return num; } 执行下,效果不错,收藏记录
JS数字千分: 1.例子:1000--->1,000 2.实现如下: salesToFormat: function (num) { var num = (num || 0).toString(), result = ''; while (num.length > 3) {//拿掉num的最后三位给result result = ',' + num.slice(-3) + result; num = num.slice(0, num.length - 3); } if (num) { resu
可以通过缩放来进行分到元的转换,同时使用正则对处理后的数字进行千分位格式化 方法1:(不丢失精度) function Fen2Yuan( num ) { if ( typeof num !== "number" || isNaN( num ) ) return null; return ( num / 100 ).toFixed( 2 ); } 方法2: var num = 370825 num=num*0.01;//分到元 num+='';//转成字符串 var reg=num.in
JS 添加千分位,测试可以使用 <script language="javascript" type="text/javascript">function comdify(n){ var re=/\d{1,3}(?=(\d{3})+$)/g; var n1=n.replace(/^(\d+)((\.\d+)?)$/,function(s,s1,s2){return s1.replace(re,"$&,")+s2;}); ret
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(/
