本博文提供了两种解决方案。
a）ajax+Handler
b) ajax+ JsonResult
| 2，a)例子代码 |
1, /Views/Home/Index.aspx 提交页面
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %> <!DOCTYPE html> <html> <head runat="server"> <title>index</title> <script src="/Scripts/jquery-1.4.4.js" type="text/javascript"></script> <script type="text/javascript"> var login = function () { var data = { "username": $.trim($("#username").val()), "pwd": $.trim($("#pwd").val()) } // $.post("/Handlers/Login.ashx", data, function (message) { // if (message.Success) { // alert(message.Msg); // } // else { // alert(message.Msg); // } // }, "json"); $.ajax({ type: "post",url:"/Handlers/Login.ashx", data: data, success: function (message) { if (message.Success) { alert(message.Msg); } else { alert(message.Msg); } },dataType:"json" }); } </script> </head> <body> <div id="nav"> <a>ajax+Handler</a> <a href="/Home/Index2">ajax+action</a> </div> <div> <h3>Login</h3> Username:<input id="username" name="username" type="text" /><br /> Userpass:<input id="pwd" name="pwd" type="password" /><br /> <button type="button" onclick="login()" >Submit</button> </div> </body> </html>
2, /Handlers/Login.ashx (处理程序)
using System.Web; using System.Web.Script.Serialization; //引用，序列化程序集 namespace Mvc1.Handlers { /// <summary> /// Login 的摘要说明 /// </summary> public class Login : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; string username = context.Request["username"]; string pwd = context.Request["pwd"]; message msg = null; if (username == "rain" && pwd == "m123") { msg = new message(true, "S"); } else { msg = new message(false, "F"); } //创建序列化对象 JavaScriptSerializer jss = new JavaScriptSerializer(); context.Response.Write(jss.Serialize(msg)); //返回json格式对象 } public bool IsReusable { get { return false; } } /// <summary> /// 提示信息 /// </summary> class message { bool success; string msg; public message(bool success, string msg) { this.success = success; this.msg = msg; } public bool Success { get { return success; } set { success = value; } } public string Msg { get { return msg; } set { msg = value; } } } } }
| 3，b)例子代码 |
1, /Views/Home/Index2.aspx
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %> <!DOCTYPE html> <html> <head runat="server"> <title>Index2</title> <script src="/Scripts/jquery-1.4.4.js" type="text/javascript"></script> <script type="text/javascript"> var login = function () { var data = { "username": $.trim($("#username").val()), "pwd": $.trim($("#pwd").val()) } // $.post("/Home/Login", data, function (message) { // if (message.success) { // alert(message.msg); // } // else { // alert(message.msg); // } // }, "json"); $.ajax({ type: "post", url: "/Home/Login", data: data, success: function (message) { if (message.Success) { alert(message.Msg); } else { alert(message.Msg); } }, dataType: "json" }); } </script> </head> <body> <div id="nav"> <a href="/Home/Index">ajax+Handler</a> <a>ajax+action</a> </div> <div> <h3> Login</h3> Username:<input id="username" name="username" type="text" /><br /> Userpass:<input id="pwd" name="pwd" type="password" /><br /> <button type="button" onclick="login()"> Submit</button> </div> </body> </html>
2, /Controllers/HomeController.cs
using System.Web.Mvc; namespace Mvc1.Controllers { public class HomeController : Controller { // // GET: /Home/ public ActionResult Index() { return View(); } // // GET: /Home/Index2 public ActionResult Index2() { return View(); } // Post: /Home/Login [HttpPost] public JsonResult Login() { string username=Request["username"]; string pwd = Request["pwd"]; message msg = null; if (username == "rain" && pwd == "m123") { msg = new message(true, "Success"); } else { msg = new message(false, "Fail"); } return Json(msg); } } class message { bool success; string msg; public message(bool success, string msg) { this.success = success; this.msg = msg; } public bool Success { get { return success; } set { success = value; } } public string Msg { get { return msg; } set { msg = value; } } } }
