MVC使用jQuery从视图向控制器传递Model的2种方法

http://blog.csdn.net/make1828/article/details/29846003

using System.ComponentModel.DataAnnotations;

namespace MvcApplication1.Models
{
public class Movie
{
public  int Id { get; set; }
[Required(ErrorMessage = "必填")]
public string Title { get; set; }
}
}

HomeController中，一个Action用来显示强类型视图，一个用来接收从视图传递过来的Model。

using System.Web.Mvc;
using MvcApplication1.Models;

namespace MvcApplication1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new Movie());
}

public ActionResult AddMovie(Movie movie)
{
return Json(new {msg = "ok"});
}

}
}

方法一：通过jQuery的serialize()方法

@model MvcApplication1.Models.Movie

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

<h2>Index</h2>

@using (Html.BeginForm("AddMovie", "Home", FormMethod.Post, new {id = "addForm"}))
{
@Html.EditorFor(m => m.Title)
@Html.ValidationMessageFor(m => m.Title)
<br/>
<input type="button" id="addMovie" value="提交"/>
}

@section scripts
{
<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>
<script type="text/javascript">
$(function() {
$('#addMovie').click(function(e) {
e.preventDefault();
if ($('#addForm').valid()) {
$.ajax({
url: $('#addForm').attr('action'),
type: $('#addForm').attr('method'),
data: $('#addForm').serialize(),
success: function(data) {
if (data.msg == 'ok') {
alert('提交成功');
}
}
});
}
});
});
</script>

}

方法二：通过jQuery的 JSON.stringify()方法把匿名对象转换成json

$(function() {
$('#addMovie').click(function(e) {
e.preventDefault();
if ($('#addForm').valid()) {
addMovie();
}
});
});

function addMovie() {
var movie = {
"Title" : $('#Title').val()
};

$.ajax({
url: '@Url.Action("AddMovie","Home")',
data: JSON.stringify(movie),
type: 'POST',
contentType: 'application/json;charset=utf-8',
success: function(data) {
if (data.msg == 'ok') {
alert('提交成功');
}
}
});
}
