Question

post methot:

function PostChartValues(meter_id, range_type_id, start_date, end_date) {
var values = $("#type_selection").val();
//values = expected values as string array
$.ajax({
    url: '/Widget/GetMeterReadingsTimeSeries',
    type: 'POST',
    data: { MeterType: meter_id, DateRangeType: range_type_id, StartDate: start_date, EndDate: end_date, Parameters: values },
    beforeSend: function () {
        $("#chart_loading_div").show();
    },
    complete: function () {
        $("#chart_loading_div").fadeOut();
        $(".grids").jqGrid('GridUnload');
        grid(meter_id, range_type_id, $("#start_date").val(), $("#end_date").val());
    },
    success: function (result) {
        $("#chart").html(result);
    },
    error: function (result) {
        alert("Seçilen kritere uygun veri bulunamadı!");
    }
});   //end ajax
} //end PostChartValues

action method:

public ActionResult GetMeterReadingsTimeSeries(int MeterType, int DateRangeType, DateTime? StartDate, DateTime? EndDate,string[] Parameters)
{
    // ...
    return PartialView("_TimeSeries", chart);
}

I debugged it. only Parameters array is null. Is there an other way to post array with jquery post?

Thanks.

You can post selected values as string then you parse it back to array. I have created basic sample below,

Markup

<script src="~/Scripts/jquery-1.7.1.js"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $('#someButton').click(function () {
            var selectedValues = [];
            $('#MyDiv input:checked').each(function () {
                selectedValues.push($(this).val());
            });
            console.log(selectedValues);
            $.ajax({
                url: 'someurl',
                type: 'POST',
                data: { values: selectedValues.join(",") }
            });
        });
    });
</script>
<button id="someButton">Do Ajax</button>
<div id="MyDiv">
    <input type="checkbox" value="test1" />
    <input type="checkbox" value="test2" />
    <input type="checkbox" value="test3" />
</div>

Controller

public class HomeController : Controller
    {       
       public void Test(string values)
        {
            string[] selectedValues = values.Split(',');
        }
    }
