The ajax request throws Invalid JSON primitive exception. So Pass the data using JSON.stringify(obj)

ajax请求抛出Invalid JSON原语异常。所以使用JSON.stringify(obj)传递数据

Ajax Request

    var prm = $("#prods").val();
    var obj = { prodID: prm };
    $.ajax({
        type: "POST",
        url: '@Url.Action("FilterCategeory", "Home")',
        contentType: "application/json; charset=utf-8",
        data : JSON.stringify(obj),
        dataType: "json",
        success: function (data) {
            alert('Success');
        },
        error: function () { alert('error'); }
    });
