MVC Ajax Helper或Jquery非同步載入部分視圖_jquery

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非同步載入部分視圖

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非同步</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非同步方式到達這裡~~";   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非同步載入部分視圖

Home/Index.cshtml視圖中需要引用jquery.unobtrusive-ajax.js檔案，從控制器返回的強型別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到達這裡~~";   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。

頁面重新整理的方式載入部分視圖方法包括：

Html.RenderPartial()
Html.RenderAction()

下面給大家介紹MVC中實現部分內容非同步載入

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;  }

    在首頁面使用下面jquery代碼非同步呼叫上面的action

 $(function () {  var id = '<%=itemid %>';  $.ajax({   type: "POST",   url: "/Student/GetItemTree",   data: { title: '<%=Model.Name %>', itemid: id, page: 1 },   beforeSend: function (data) { //取回資料前    $("#itemTree").html('<span style="padding:5">資料載入中...</span>');   },   error: function (data) { //發生錯誤時//    debugger;   },   success: function (data) { //成功返回時    $("#itemTree").html(data);   }  });

   最後在分部視圖GetItemTree.ascx中寫上你要返回的資料結構即可
   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>
