Question

I have a controller defined as:

        [AcceptVerbs(HttpVerbs.Post)]
        public JsonResult PostMoreData(DataContracts.Address address, DataContracts.GeoLocation geoLocation)
        {
            return Json("test");
        }

where DataContracts.Address and DataContracts.GeoLocation are complex types.

From my View i’m trying to post using jQuery as such:

        function PostMoreData() {

            var JsonAddress = {

                "Building": $('Building').val(),
                "UnitNumber": $('UnitNumber').val(),
                "StreetNumber": $('StreetNumber').val(),
                "StreetName": $('StreetName').val(),
                "StreetType": $('StreetType').val(),
                "Suburb": $('Suburb').val(),
                "State": $('State').val(),
                "Postcode": $('Postcode').val(),
                "MonthsAtAddress": $('MonthsAtAddress').val()

            };

            var JsonGeoLocation = {
                "Latitude": $('Latitude').val(),
                "Longitude": $('Longitude').val()
            };


            jQuery.post("/AddressValidation/PostMoreData", {address: JsonAddress, geoLocation: JsonGeoLocation}, function(data, textStatus) {
                if (textStatus == "success") {
                    var result = eval(data);
                    if (result.length > 0) {
                        alert(result);
                    }
                }
            }, "json");
        } 

However, on the controller, I get nulls.

It works if my Controller takes just 1 argument and I post just one object.

        [AcceptVerbs(HttpVerbs.Post)]
        public JsonResult PostMoreData(DataContracts.Address address)
        {
            return Json("test");
        }

        function PostMoreData() {

            var JsonAddress = {

                "Building": $('Building').val(),
                "UnitNumber": $('UnitNumber').val(),
                "StreetNumber": $('StreetNumber').val(),
                "StreetName": $('StreetName').val(),
                "StreetType": $('StreetType').val(),
                "Suburb": $('Suburb').val(),
                "State": $('State').val(),
                "Postcode": $('Postcode').val(),
                "MonthsAtAddress": $('MonthsAtAddress').val()

            };


            jQuery.post("/AddressValidation/PostMoreData", JsonAddress, function(data, textStatus) {
                if (textStatus == "success") {
                    var result = eval(data);
                    if (result.length > 0) {
                        alert(result);
                    }
                }
            }, "json");
        } 

Any ideas how i can post more than one object?

Thank you everyone for your input on this issue.

At this stage, we have departed from using jquery to post complex types to controllers. Instead we use the ms ajax framework to do that. ms ajax post nicely binds the complex types automatically out of the box.

So our solution now uses a mix of jquery and ms ajax framework.
