js千分位处理

Posted 2022-01-02 muyeh

一.去掉千分位

 function removeThousands(num)
 
    var x = num.split(‘,‘);
    return parseFloat(x.join(""));
 

二.添加千分位

 

  function addThousands(num) 
   var reg = /\d1,3(?=(\d3)+$)/g; 
   if ( num &&num.toString().indexOf(‘.‘) == -1) 
     return (num + ‘‘).replace(reg, ‘$&,‘); 
    else 
        return num.toString().replace(/(\d)(?=(\d3)+\.)/g, function ($0, $1) 
            return $1 + ",";
             );
