MVC Ajax Helper或jQuery异步方式加载部分视图

Model:

namespace MvcApplication1.Models
{
public class Team
{
public string Preletter { get; set; }
public string Name { get; set; }
}
}

通过jQuery异步加载部分视图

Home/Index.cshtml视图中：

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

<h2>Index</h2>

<div>
<a href="#" id="a">通过jQuery异步</a> <br/>
</div>
<div id="result">

</div>
@section scripts
{
<script type="text/javascript">
$(function() {
$('#a').click(function() {
$.ajax({
url: '@Url.Action("Index","Home")',
data: { pre: 'B' },
type: 'POST',
success: function(data) {
$('#result').empty().append(data);
}
});
return false;
});
});
</script>
}

HomeController控制器中：

using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;
using MvcApplication1.Models;

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

[HttpPost]
public ActionResult Index(string pre)
{
var result = GetAllTeams().Where(t => t.Preletter == pre).ToList();
ViewBag.msg = "通过jQuery异步方式到达这里~~";
return PartialView("TeamY", result);
}

private List<Team> GetAllTeams()
{
return new List<Team>()
{
new Team(){Name = "巴西队", Preletter = "B"},
new Team(){Name = "克罗地亚队", Preletter = "K"},
new Team(){Name = "巴拉圭", Preletter = "B"},
new Team(){Name = "韩国", Preletter = "K"}
};
}
}
}

部分视图TeamY.cshtml：

@model IEnumerable<MvcApplication1.Models.Team>

@{
var result = string.Empty;
foreach (var item in Model)
{
result += item.Name + ",";
}
}

@ViewBag.msg.ToString()
<br/>
@result.Substring(0,result.Length - 1)

通过MVC Ajax Helper异步加载部分视图

Home/Index.cshtml视图中需要引用jquery.unobtrusive-ajax.js文件，从控制器返回的强类型部分视图内容呈现到UpdateTargetId指定的div中。

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

<h2>Index</h2>

<div>
@Ajax.ActionLink("通过MVC Ajax Helper","Load","Home", new {pre = "K"}, new AjaxOptions(){UpdateTargetId = "result1"})
</div>
<div id="result1">
</div>

HomeController控制器中：

using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;
using MvcApplication1.Models;

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

public ActionResult Load(string pre)
{
var result = GetAllTeams().Where(t => t.Preletter == pre).ToList();
ViewBag.msg = "通过MVC Ajax Helper到达这里~~";
return PartialView("TeamY", result);
}

private List<Team> GetAllTeams()
{
return new List<Team>()
{
new Team(){Name = "巴西队", Preletter = "B"},
new Team(){Name = "克罗地亚队", Preletter = "K"},
new Team(){Name = "巴拉圭", Preletter = "B"},
new Team(){Name = "韩国", Preletter = "K"}
};
}
}
}

部分视图和上一种方式一样。

页面刷新的方式加载部分视图方法包括：
Html.RenderPartial()
Html.RenderAction()
