一、使用System.Web.Mvc.Ajax
1.1 System.Web.Mvc.Ajax.BeginForm
1.2 System.Web.Mvc.Ajax.ActionLink
二、手工打造自己的“非介入式”Javascript”
一、使用System.Web.Mvc.Ajax
1.1 System.Web.Mvc.Ajax.BeginForm
第一步:用Ajax.BeginForm创建Form
@using (Ajax.BeginForm( new AjaxOptions() { HttpMethod = "post", Url = @Url.Action("Index","Reviews"), InsertionMode = InsertionMode.Replace, UpdateTargetId = "restaurantList", LoadingElementId = "loding", LoadingElementDuration = 2000 })) { <input type="search" name="searchItem"/> <input type="submit" value="按名称搜索"/> }
最终生成的form如下:
<form id="form0" method="post" data-ajax-url="/Reviews" data-ajax-update="#restaurantList" data-ajax-mode="replace" data-ajax-method="post" data-ajax-loading-duration="2000" data-ajax-loading="#loding" data-ajax="true" action="/Reviews" novalidate="novalidate">
第二步:创建Ajax.BeginForm的new AjaxOptions()对象的Url指向的Action
new AjaxOptions() { ... Url = @Url.Action("Index","Reviews") ... } public ActionResult Index(string searchKey = null) { var model = _restaurantReviews.Where(r => searchKey == null || r.Name.ToLower().Contains(searchKey.ToLower().Trim())) .OrderByDescending(r => r.Rating) .Take(100) .Select(r=>new RestaurantReview() { City = r.City, Country = r.Country, Id = r.Id, Name = r.Name, Rating = r.Rating }).ToList(); if (Request.IsAjaxRequest()) { System.Threading.Thread.Sleep(1000 * 3);//模拟处理数据需要的时间 //return View(model)会返回整个页面,所以返回部分视图。 return PartialView("_RestaurantPatialView", model); } return View(model); }
注意:
关于使用System.Web.Mvc.Ajax的说明:
Controller的Action方法:
(1)当显式添加[HttpPost],传给System.Web.Mvc.Ajax的AjaxOptions()的HttpMethod只能为 "post",
(2)当显式添加[HttpGet],传给System.Web.Mvc.Ajax的AjaxOptions()的HttpMethod只能为 "get",
(3)当都没有显式添加[HttpPost]和[HttpGet],传给System.Web.Mvc.Ajax的AjaxOptions()的HttpMethod可以为 "get"也可以为"post",
第三步:添加要承载更新页面的html元素,
