Question

I want to parse 2 strings (Just testing with one atm( consiting of a date from a datepicker and hour and minute from 2 textfields. But I cant figure out how to parse data from my ajax call to the method I call, I know its called as I checked with a breakpoint, but its parameter is just null.

My ajax:

$('.datein').change(function () {
    alert("datein changed");
    //send servervalidering ajax
    var result = false;
    $.ajax({ url: "Resource/isDateValid/",
            data: ($('#resource_datein').val() + "-" + $('#resource_hourin').val() + "-" + $('#resource_minutein').val()),
        type: "POST",
        sucess: ajaxsuccess(result)
    }
    );
});

My methodcall on success

function ajaxsuccess(result) {
    alert("ajax lykkes!" + result);
}

And the controller method which is part of public class ResourceController : DataTablesController

    [HttpPost]
    public bool isDateValid(string dateIn)
    {

        return true;
    }

string dateIn just returns null if I set a date

Answer 1

try something like

//js

var data = $("myform").serialize(); //Might be serializeArray() not on dev machine sorry

$.post("Resource/isDateValid/", data, function(data){
   alert(data.Success);
}, "json");

Controller (assuming Resource is a class because of the underscore in the ids…)

[HttpPost]
public JsonResult(Resource resource) //or (DateTime resource_datein, int resource_hourin)
{
    bool success = true;

    //Do something with posted data

    return Json(new { Success = success});
}

EDIT (re comment)

take the () off the AjaxSuccess function call in the $.post

$('.datein').change(function () {
            //send servervalidering ajax
            var data = $(".datein").serialize();
            $.post("Resource/isDateValid", data, ajaxsuccess, "text");
        });

with

function ajaxsuccess(data)
{
   alert(data.Success); // in your case alert(data); because it's "text"?
}

also because you are not serializing the entire form your data should be:

var data = {dateIn : $(".datein").val()};
