JS金额保留两位小数

 

// handlePrice(0)  输出0.00
// handlePrice(1.9898)  输出1.98
// handlePrice(123456798)  输出123,456,798.00


handlePrice(value){
	console.log("value",value)
	if(value){
		var intPart = Number(value) | 0; //获取整数部分
		var intPartFormat = intPart.toString().replace(/(\d)(?=(?:\d{3})+$)/g, '$1,'); //将整数部分逢三一断
		var floatPart = ".00"; //预定义小数部分
		var value2Array = value.toString().split(".");
		//=2表示数据有小数位
		if (value2Array.length == 2) {
			floatPart = value2Array[1].toString(); //拿到小数部分
			if (floatPart.length == 1) { //补0,实际上用不着
				return intPartFormat + "." + floatPart + '0';
			} else {
				return intPartFormat + "." + floatPart;
			}
		} else {
			return intPartFormat + floatPart;
