1.控制器
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace Mvcfy.Controllers
{
public class AjaxController : Controller
{
//
// GET: /Ajax/
public ActionResult Index()
{
return View();
}
public ActionResult GetTime()
{
return Content(DateTime.Now.ToString());
}
}
}
2.展示页
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<!DOCTYPE html>
<html>
<head runat="server">
<meta name="viewport" content="width=device-width" />
<title>Index</title>
<script src="../../Scripts/jquery-1.7.1.js"></script>
<script type="text/javascript">
$(function () {
$("#btn1").click(function () {
$.ajax({
url: "/Ajax/GetTime",
async:false,//默认是true 异步
data:"",
type:"get",
success:function(data){
alert(data);
}
});
alert("先出来是异步，后出来是同步");
});
});
</script>
</head>
<body>
<div>
<input type="button" value="得到当前时间" id="btn1" />
</div>
</body>
</html>
3.微软自己的ajax
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>Index</title>
<%--第一步引用脚本--%>
<script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$("#loading").css("display", "none");
function showOk() {
alert("ok");
}
});
</script>
</head>
<body>
<%-- 第二步：写Ajax表单--%>
<%--<%: %>
<%= Html.Encode( getSTring()) %>--%>
<hr/>
<%--微软提供的ajax--%>
<% using(Ajax.BeginForm("GetContent",new AjaxOptions()
{
Confirm="是否要提交啊？",HttpMethod="Post",UpdateTargetId="resultDiv" ,
InsertionMode= InsertionMode.Replace,//
OnSuccess="showOk" ,
LoadingElementId="loading"
// UpdateTargetId 数据更新位置的控件id
//OnSuccess 成功之后的回调函数
//LoadingElementId 处理过程中显示的控件id
}) )
{
%>
<input type="text" name="txtName"/>
<input type="submit" value="提交"/>
<% } %>
<div id="resultDiv">
</div>
<div id="loading">
<img src="../../Content/ico_loading2.gif" />
</div>
</body>
