廢話不多說了，直接給大家貼代碼了。
Model:
namespace MvcApplication1.Models{ public class Team { public string Preletter { get; set; } public string Name { get; set; } }}通過jQuery異步加載部分視圖
Home/Index.cshtml視圖中：
@{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml";}<h2>Index</h2><div> <a href="#" id="a">通過jQuery異步</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 = "通過jQuery異步方式到達這里~~"; return PartialView("TeamY", result); } private List<Team> GetAllTeams() { return new List<Team>() { new Team(){Name = "巴西隊", Preletter = "B"}, new Team(){Name = "克羅地亞隊", Preletter = "K"}, new Team(){Name = "巴拉圭", Preletter = "B"}, new Team(){Name = "韓國", Preletter = "K"} }; } }}部分視圖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)通過MVC Ajax Helper異步加載部分視圖
Home/Index.cshtml視圖中需要引用jquery.unobtrusive-ajax.js文件，從控制器返回的強類型部分視圖內容呈現到UpdateTargetId指定的div中。
@{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml";}<h2>Index</h2><div> @Ajax.ActionLink("通過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 = "通過MVC Ajax Helper到達這里~~"; return PartialView("TeamY", result); } private List<Team> GetAllTeams() { return new List<Team>() { new Team(){Name = "巴西隊", Preletter = "B"}, new Team(){Name = "克羅地亞隊", Preletter = "K"}, new Team(){Name = "巴拉圭", Preletter = "B"}, new Team(){Name = "韓國", Preletter = "K"} }; } }}部分視圖和上一種方式一樣。
頁面刷新的方式加載部分視圖方法包括：
Html.RenderPartial()
Html.RenderAction()
下面給大家介紹MVC中實現部分內容異步加載
action中定義一個得到結果集的方法
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; }在主頁面使用下面jquery代碼異步調用上面的action
$(function () { var id = '<%=itemid %>'; $.ajax({ type: "POST", url: "/Student/GetItemTree", data: { title: '<%=Model.Name %>', itemid: id, page: 1 }, beforeSend: function (data) { //取回數據前 $("#itemTree").html('<span style="padding:5">數據加載中...</span>'); }, error: function (data) { //發生錯誤時// debugger; }, success: function (data) { //成功返回時 $("#itemTree").html(data); } }); 最后在分部視圖GetItemTree.ascx中寫上你要返回的數據結構即可
注意一點就是，如果涉及到分頁，要用AJAX分頁方式
<div style="float: left"> <%=Html.AjaxPager(resItemResourceBefore, "itemTree", "GetItemTree", "Student")%> </div>
