MVC Ajax Helper或Jquery异步加载部分视图

废话不多说了，直接给大家贴代码了。
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（）
下面给大家介绍MVC中实现部分内容异步加载
action中定义一个得到结果集的方法

public ActionResult GetItemTree（string title, int itemid, int? page）{ pp = new PagingParam（page ?? 1, VConfig.WebConstConfig.PageSize）; Common.Page.PagedList<Entity.Res_Item_Resource_R> res_Item_Resource_R = iResourceService.GetRes_Item_Resource_RByItemId（itemid, pp）; ViewData["res_Item_Resource_R"] = res_Item_Resource_R; res_Item_Resource_R.AddParameters = new System.Collections.Specialized.NameValueCollection（）; res_Item_Resource_R.AddParameters.Add（"title", title）; res_Item_Resource_R.AddParameters.Add（"itemid", itemid.ToString（））; ViewResult vr = new ViewResult {ViewData = ViewData,MasterName = "", }; return vr;}

在主页面使用下面jquery代码异步调用上面的action

 $（function （） {var id = "<%=itemid %>";$.ajax（{ type: "POST", url: "/Student/GetItemTree", data: { title: "<%=Model.Name %>", itemid: id, page: 1 }, beforeSend: function （data） { //取回数据前$（"#itemTree"）.html（"<span style="padding:5">数据加载中...</span>"）; }, error: function （data） { //发生错误时//debugger; }, success: function （data） { //成功返回时$（"#itemTree"）.html（data）; }}）;

最后在分部视图GetItemTree.ascx中写上你要返回的数据结构即可
注意一点就是，如果涉及到分页，要用AJAX分页方式

<div style="float: left"><%=Html.AjaxPager（resItemResourceBefore, "itemTree", "GetItemTree", "Student"）%> </div>
