JavaScript基础 跳出循环

javascript的foreach不能跳出循环 使用forin

var checkStatus = table.checkStatus('LAY-logistics-fee-order-manage')
                , checkData = checkStatus.data; //得到选中的数据
console.log("checkData", checkData);
let checkedLogisticsServiceId = checkData[0].logisticsServiceId;
let checkedSettleCurrency = checkData[0].settleCurrency;
let errorMsg = "";
for (const i in checkData) {
    if (checkedLogisticsServiceId !== checkData[i].logisticsServiceId){
        errorMsg = "请选择同一物流服务商";
        break;
    }
    if (checkedSettleCurrency !== checkData[i].settleCurrency){
        errorMsg = "请选择同一结算币种";
        break;
    }
}
if (errorMsg !== ""){
    layer.msg(errorMsg);
    return false;
}
