MVC Ajax Helper或Jquery异步加载部分视图

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
