1、转成千分位,保留两位

comdify(n) {
  let num = Number(n);
  let re = /\d{1,3}(?=(\d{3})+$)/g;
  let n1 = num.toFixed(2).replace(/^(\d+)((\.\d+)?)$/, function (s, s1, s2) {
    return s1.replace(re, "$&,") + s2;
  });
  return n1;
},

2、去除千分位

delcommafy(num){//去除千分位中的‘,’
  if(num&&num!='undefined'&&num!='null'){
    let numS = num;
    numS = numS.toString();
    numS = numS.replace(/,/gi, '');
    return numS;
  }else {
    return num;
  }
},
