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="#">通过jQuery异步</a> <br/> </div> <div> </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> </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>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> <%=Html.AjaxPager(resItemResourceBefore, "itemTree", "GetItemTree", "Student")%> </div>
