也就是添加添加AjaxOptionsd对象的UpdateTargetId 参数指定的Id为restaurantList的html元素:
这里在页面中添加:id为restaurantList的<div>:
<div id="restaurantList">... </div>
第四步:(可选)为增强用户体验,添加AjaxOption对象的LoadingElementId参数指定的Id为loding的html元素:
new AjaxOptions()
{
....
LoadingElementId = "loding",
LoadingElementDuration = 2000
}))
这里在页面中添加:id为loding的元素,添加了包含一个动态的刷新图片<div>:

cshtml文件中添加:
<div id="loding" hidden="hidden">
<img class="smallLoadingImg" src="@Url.Content("~/Content/images/loading.gif")" />
</div>
1.2 System.Web.Mvc.Ajax.ActionLink
System.Web.Mvc.Ajax.ActionLink与System.Web.Mvc.Ajax.BeginForm用法基本一致
第一步:使用System.Web.Mvc.Ajax.ActionLink创建超链接
@*@Html.ActionLink(item.Name, "Details", "Reviews",new{id = item.Id},new {@class ="isStar"})*@
@*<a class="isStar" href="@Url.Action("Details","Reviews", new {id = item.Id})">@item.Name</a>*@
@*使用Ajax的超链接*@
@{
var ajaxOptions = new AjaxOptions()
{
HttpMethod = "post",
//Url = @Url.Action(""),
UpdateTargetId = "renderBody",
InsertionMode = InsertionMode.Replace,
LoadingElementId = "loding",
LoadingElementDuration = 2000
};
@Ajax.ActionLink(item.Name, "Details", "Reviews", new { id = item.Id }, ajaxOptions, new {@class="isStar"})
}
对应生成的最终html为:
<a class="isStar" href="/Reviews/Details/1" data-ajax-update="#renderBody" data-ajax-mode="replace" data-ajax-method="post" data-ajax-loading-duration="2000" data-ajax-loading="#loding" data-ajax="true">
第二步:定义出来响应超链接的Action:
/// <summary>
///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",
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
public ActionResult Details(int id=1)
{
var model = (from r in _restaurantReviews
where r.Id == id
select r).FirstOrDefault();
if (Request.IsAjaxRequest())
{
return PartialView("_RestaurantDetails", model);
}
return View(model);
}
