vue中过滤数据小数点前使用千位分隔符 小数点后不使用且保留位数_vue千位逗号分隔符与小数点

import Vue from 'vue'

//全局过滤器，金额千分位
Vue.filter('moneyFormat', function (value) {
  if (value != undefined) {
    return value.toFixed(2).toString().replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,");
  }
})
//全局过滤器，数量2位
Vue.filter('qtyFormat', function (value) {
  if (value != undefined) {
    return value.toFixed(2);
  }
})
// bit小数位
Vue.filter('customFormat', function (value,bit) {
  if(!value){
    value = 0
  }
  if (value != undefined) {
    var valueCopy =Number(value).toFixed(bit).toString()
    // 截取小数点前的数据
    var intNumber = valueCopy.substring(0,valueCopy.indexOf("."));
    // 小数点前的数据使用千位分割
    intNumber =intNumber.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,");
    // 截取小数点后的数据
    var laterNumber =valueCopy.replace(/\d+\.(\d*)/,"$1")
    //有负数的数据重截取
    laterNumber =laterNumber.replace('-','')
    // return Number(value).toFixed(bit).toString().replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,");
    return intNumber+"."+laterNumber;
  }
})

Vue.filter('timestampToTime' ,function(timestamp) {
  // 计算年月日时分的函数
  var date = new Date(timestamp)
  var Y = date.getFullYear() + '-'
  var M = (date.getMonth() + 1) + '-'
  var D = date.getDate() + ' '
  var h = date.getHours() + ':'
  var m = date.getMinutes() + ':'
  var s = date.getSeconds()
  return Y + M + D + h + m + s
})
Vue.filter('deptLevel' ,function(value) {
  console.log(value)
  // 计算年月日时分的函数
  var dept = []
  for (let index = 0; index < value.length; index++) {
    if(value[index].deptLevel == "1"){
      dept.push(value[index])
    }
  }
  return dept;
})

代码中使用

 <el-table-column label="成本总价" align="center" prop="stockCost">
            <template slot-scope="scope">
              <p>{{form.detailList[scope.$index].stockCost | customFormat(2)}}</p>
            </template>
          </el-table-column>
 <el-table-column label="总售价" align="center" prop="sellingSum">
            <template slot-scope="scope">
              <p>{{form.detailList[scope.$index].sellingSum | customFormat(2)}}</p>
            </template>
