数字类型转千分位

		let number = 2323234355.99;
		function f(num){
			const reg = /\B(?=(\d{3})+$)/g,
			 n = num.toString().split('.');
			return `${n[0].replace(reg, ',')}.${n[1]}`
		}
		console.log(f(number))

 

　　

// 千分位格式

    return "---";
  }
  val = Number(val).toLocaleString();

  }
  return val;
  // return (val + "").replace(/(\d{1,3})(?=(\d{3})+(?:$|\.))/g, "$1,");
