请求url

var validateUrl = "/api/order/checkProduct"; // 校验请求controller

var validateReq = {
    "arrivalDate": arrivalDate,
    "departureDate": $("#inputDepartureDate").val(),
    "hotelId": $("#inputHotelId").val(),
    "roomTypeID": $("#inputRoomTypeId").val(),
    "ratePlanId": $("#inputRatePlanId").val(),
    "earliestArrivalTime": (nextHour.substring(0,1) == "0"
        ? arrivalNextDate: arrivalDate) + " " + nextHour + ":00",
    "latestArrivalTime": ($('#btnArrivalTime').attr("value").substring(0,1) 
        == "0"? arrivalNextDate: arrivalDate) + " " + $('#btnArrivalTime').attr("value"),
    "numberOfRooms": $("#btnRoomNum").attr("value"),
    "totalPrice": parseFloat($('#inputTotalRate').val())
};

js请求后端

// 请求校验参数
var validateResult = ajaxCommonForJson(validateUrl, "POST", validateReq);

// 通过则继续下单，否则提示错误
if (validateResult != null) {
    if (validateResult.validate) {
        if (validateResult.message != null && validateResult.message != "") {
            if( !confirm( validateResult.message)) {
                return;
            }
        }
    } else {
        alert(validateResult.errorMessage);
        return;
    }
