Ajax Question

Submit form using AJAX in Asp.Net mvc 4

I'm trying to learn asp.net and so far I can load other page contents without refreshing using

Ajax.Actionlink
and
AjaxOptions()
but I can't figure it out how to use ajax when submitting a form. I did a lot of googling but couldn't find the appropriate solution. Here are my codes,

Controller page

namespace CrudMvc.Controllers
{
public class HomeController : Controller
{
sampleDBEntities db = new sampleDBEntities();
//
// GET: /Home/

public ActionResult Index()
{
return View(db.myTables.ToList());
}

public PartialViewResult Details(int id = 0)
{
myTable Table = db.myTables.Find(id);
return PartialView(Table);
}

[HttpGet]
public PartialViewResult Create()
{
return PartialView();
}

[HttpPost]
public ActionResult Create(myTable table)
{
if (ModelState.IsValid)
{
db.myTables.Add(table);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(table);
}

protected override void Dispose(bool disposing)
{
db.Dispose();
base.Dispose(disposing);
}
}
}


Index
View page

@model IEnumerable<CrudMvc.Models.myTable>

@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}

<script src="~/Scripts/jquery-1.7.1.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>

<h2>Index</h2>

<p>
@Ajax.ActionLink("Add New", "Create", new AjaxOptions()
{
HttpMethod = "GET",
UpdateTargetId = "info",
InsertionMode = InsertionMode.Replace
})
</p>
<div id="main">
<table>
<tr>
<th>
@Html.DisplayNameFor(model => model.name)
</th>
<th>Action</th>
</tr>

@foreach (var item in Model) {
<tr>
<td>
@Html.DisplayFor(modelItem => item.name)
</td>
<td>
@Ajax.ActionLink("Details", "Details", new{ id=item.id}, new AjaxOptions()
{
HttpMethod = "GET",
UpdateTargetId = "info",
InsertionMode = InsertionMode.Replace
})
</td>
</tr>
}
</table>
</div>
<div id="info"></div>


Create
View Page

@model CrudMvc.Models.myTable

@{
ViewBag.Title = "Create";
Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Create</h2>

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)

<fieldset>
<legend>myTable</legend>

<div class="editor-label">
@Html.LabelFor(model => model.id)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.id)
@Html.ValidationMessageFor(model => model.id)
</div>

<div class="editor-label">
@Html.LabelFor(model => model.name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.name)
@Html.ValidationMessageFor(model => model.name)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}

<script>
var form = $('#main');
$.ajax({
cache: false,
async: true,
type: "POST",
url: form.attr('action'),
data: form.serialize(),
success: function (data) {
alert(data);
}
});
</script>

<div>
@Html.ActionLink("Back to List", "Index")
</div>

@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}

Answer

Here goes the complete example -

Lets create a simple model -

public class Details
{
    public string Name { get; set; }
    public string Email { get; set; }
}

Now lets create couple of Actions to make GET and POST requests using AJAX BEGINFORM -

    static List<Details> details = new List<Details>(); 
    public ActionResult GetMe()
    {
        return View();
    }

    public ActionResult SaveData(Details d)
    {
        details.Add(d);
        return Json(details.Count, JsonRequestBehavior.AllowGet);
    }

Then lets create a simple view which will host Ajax.BeginForm() -

@model RamiSamples.Controllers.Details

@{
    ViewBag.Title = "Ajax";
}

<h2>Ajax</h2>
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>

@using (Ajax.BeginForm("SaveData", new AjaxOptions()
{
    InsertionMode = InsertionMode.Replace,
    UpdateTargetId = "dane"
}))
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>Details</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.Name)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Name)
            @Html.ValidationMessageFor(model => model.Name)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Email)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Email)
            @Html.ValidationMessageFor(model => model.Email)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div id="dane">
    Number of Details : 
</div>

Now when the page gets rendered -

Now when you enter data and click on create button -

And then the page will automatically updated with the number of additions as shown below -
