javascript - How to pass model from view to controller when click button in MVC?

Index - View

@model SendAFaxWeb.Models.Send
//view start here
<body>
    <div>
        <h2>Test Upload File</h2>
        <form action="@Url.Action("Index", "Home")" id="form" method="post" enctype="multipart/form-data">
            @Html.AntiForgeryToken()
            <div class="form-group">
                <label>Fax Number:</label>
                @Html.TextBoxFor(m => m.Recipients[0].Number)
             </div>

            <div class="form-group">
                <label>Select File:</label>
                <input type="file" name="files" id="file" multiple="multiple" onchange="this.form.submit();" />
            </div>

            <div>
              @if (Model != null)
                 {
                   foreach (var item in Model.Documents)
                    {
                       <li>FileName: @item.Name</li>
                    }
                  }
             </div>
    </form>

    <input type="submit" name="send" value="Send" id="btnSend" />

    </div>
</body>

Javascript- the javascript doesnt work

<script type="text/javascript">
    $(document).ready(function () {
     $("#btnSend").click(function () {
        alert("button click");
        e.preventDefault();

        var model = @Html.Raw(Json.Encode(Model))
        $.ajax({
            type: 'post',
            url: '@Url.Action("Send", "Home")',
            data: JSON.stringify({ contact: model }),
            contentType: 'application/json; charset=utf-8',
            dataType: "json",
            success: function (data) {
                alert(data);
            }
        });
        });
    });

</script>

Controller

public ActionResult Send(Send contact)
{
    //some code here
}

I tried to pass model by using javascript to the controller, but its not working. The alert in javascript also not popup. Can any one tell me what wrong with the code.

You can do it using the below code

@model PK.LifeStyles.Web.Models.Reimbursement //model declaration on top

<button type="button" onclick="location.href='@Url.Action("ActionName", "ControllerName",Model)'">

Your code behind should look something like this

    public ActionResult Save(Reimbursement data)
    {
      // your  code
    }
   //just some random class
   public class Reimbursement{
         public string Destination { get; set; }
   }
