Question

I am trying to do some jquery.post where I pass back the Model. I been searching google but can’t really find a detail example of $.post with data that passes back Model.

Assuming you have a strongly typed view with a model you could use the $.ajax method to send your entire model to the server using a JSON AJAX request:

@model MyViewModel

<script type="text/javascript">
    var model = @Html.Raw(Json.Encode(Model));
    $.ajax({
        url: '@Url.Action("Foo")',
        type: 'POST',
        contentType: 'application/json; charset=utf-8',
        data: JSON.stringify({ model: model }),
        success: function(result) {
            // TODO: process the result from the server
        }
    });
</script>

and the corresponding controller action to which we send the POST request:

[HttpPost]
public ActionResult Foo(MyViewModel model)
{
    // TODO: do something with the request and return a result
}
