Passing HTML form data from View to Controller in ASP.NET MVC

Question

I am pretty new to JavaScript and I am trying to get my form data and built it into a JSON object. Then make an AJAX call to get the form's results and pass display the form results within a ajax.done() function. Right now I have the values of the form data just being "alerted". How do I go about creating a JSON Object and adding it to my AJAX call?

HTML

<div class="container">
<form action="" id="sasTokenOptions" method="post">
    <div class="row">
        <div class="col-xs-6">
            <div class="card">
                <div class="card-title">SAS Token Duration</div>
                <p></p>
                <p>Please select a the duration of the SAS Token.</p>
            </div>

            <div class="container">
                <div class="radio" id="">
                    <label><input type="radio" name="optradio" value="1" />1 hour</label>
                </div>
                <div class="radio">
                    <label><input type="radio" name="optradio" value="24" />24 hours</label>
                </div>
                <div class="radio">
                    <label><input type="radio" name="optradio" value="720" />30 days</label>
                </div>
            </div>
        </div>

        <div class="col-xs-6">

            <div class="card">
                <div class="card-title">SAS Token Access Permission</div>
                <p></p>
                <p>Please select the SAS Token's permission.</p>
            </div>
            <div class="container">
                <div class="checkbox">
                    <label><input type="checkbox" name="optcheck" value="1">Read</label>
                </div>
                <div class="checkbox">
                    <label><input type="checkbox" name="optcheck" value="2">Write</label>
                </div>
                <div class="checkbox">
                    <label><input type="checkbox" name="optcheck" value="8">List</label>
                </div>
                <div class="checkbox">
                    <label><input type="checkbox" name="optcheck" value="4">Delete</label>
                </div>
            </div>
        </div>
    </div>
    <div class="col-xs-6">
        <button type="button" class="btn btn-primary btn-sm" id="btn-genSas">Generate SAS Token</button>
    </div>
</form>
</div>

JavaScript

$(".sasToken").hide();

$(document).ready(function () {

$('input[name=optradio]').on('change', function () {
    alert($('input[name=optradio]:checked', '#sasTokenOptions').val());
})

$('input[name=optcheck]').on('change', function () {
    var result = null; 
    $('input[name=optcheck]:checked', "#sasTokenOptions").each(function () {

        switch ($('input[name=optcheck]:checked', "#sasTokenOptions").val()) {
            case( $('input[name=optcheck]:checked', "#sasTokenOptions") == 1 || "1"):
                result = "Read";
                break;
            case ($('input[name=optcheck]:checked', "#sasTokenOptions") == 2 || "2"): 
                result = "Write";
                break;
            case ($('input[name=optcheck]:checked', "#sasTokenOptions") == 8 || "8"):
                result = "List";
                break;
            case ($('input[name=optcheck]:checked', "#sasTokenOptions") == 4 || "4"):
                result = "Delete";
                break;
        }

        alert(result);
    })
});




$("#btn-genSas").click(function () {
    $.ajax({
        url: "/GenerateSasController/GenerateSas",
        method: post,
        data: data
    }).done(function (responce) {
        var token = FormData(responce);
        $("#SasToken").text(token).show();
    });
    $(".sasToken").show();
    //generate a SAS and display it to screen
});

});

Controller

 public class GenerateSasController : Controller
{
    // GET: GenerateSas
    public ActionResult Index()
    {
        return View(new GenerateSasViewModel());
    }

    [HttpPost]
    public ActionResult GenerateSas(string optradio, string optcheck)
    {
        //if (ModelState.IsValid)
        //{
        //    var connection = new GenerateSas()
        //    {
        //        SasDuration = viewModel.SASDuration,
        //        SasPrivilages = viewModel.SASPermissions
        //    };
        //}

        string connectionString = "DefaultEndpointsProtocol=https;AccountName=;AccountKey=;";

        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);

        CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

        CloudBlobContainer container = blobClient.GetContainerReference("publiccontainer");

        var sasToken = container.GetSharedAccessSignature(new SharedAccessBlobPolicy()
        {
            //cast the enum to an int 

            Permissions =  SharedAccessBlobPermissions.Read
        });

        return View();
    }
}

I would create the JSON object like this:

var data = {
    optradio: "",
    optcheck: "",
}

Then all you would need to do is set the JSON objects properties based on the selected values of your radio buttons/checkboxes in your change events. i.e.

data.optradio = $('input[name=optradio]:checked', '#sasTokenOptions').val();

The data that you are passing into your ajax call would be your object that you set and sent up to the server.

Create public shared method (VB) or public static method (C#) using the WebMethod directive. This will make your method accessible like a web service. Then use jQuery to make the ajaxCall pointing to your webservice. In that ajax call you will provide the data in between curly brackets...this will be converted to a JSON object.
