爱上MVC3系列~Html.BeginForm与Ajax.BeginForm

Html.BeginForm与Ajax.BeginForm都是MVC架构中的表单元素,它们从字面上可以看到区别,即Html.BeginForm是普通的表单提交,而Ajax.BeginForm是支持异步的表单提交,这对于我们开发者来说是一个福音,我们不用再自己去用JQ代码了,直接用MVC自代的Ajax.BeginForm就可以很容易的完成一个异步的表单提交动作。

Html.BeginForm的原型解释:

 1 @using (Html.BeginForm()) {} //提交到当前页面 2  3 @using (Html.BeginForm(new {} )) {} //提交到当前页面,并可以传递参数 4  5 @using (Html.BeginForm("action","controller")) {} //提交到指定controller下的action中 6  7 @using (Html.BeginForm("action","controller",FormMethod.POST)) {} //提交到指定controller下的action中,并指定提交方式 8  9 FormMethod枚举如下:   10 11  // 摘要:12     //     枚举窗体的 HTTP 请求类型。13     public enum FormMethod14     {15         // 摘要:16         //     指定 GET 请求。17         Get = 0,18         //19         // 摘要:20         //     指定 POST 请求。21         Post = 1,22     }

 

Ajax.BeginForm异步表单原型解释

 1 @using (Ajax.BeginForm( 2     new AjaxOptions 3     { 4         UpdateTargetId = "UserLogOnContainer", 5         HttpMethod = "Post", 6         OnSuccess = " ", 7     })){} //提交到当前页面,提交方式为Post,异步更新模块ID为UserLogOnContainer 8  9  @using (Ajax.BeginForm("action", "controller", null,10     new AjaxOptions11     {12         UpdateTargetId = "UserLogOnContainer",13         HttpMethod = "Post",14         OnSuccess = " ",15     }))16     {} //提交到指定controller下的action,提交方式为Post,异步更新模块ID为UserLogOnContainer

 

下面看一下Ajax.BeginForm的例子,一个用户登陆的DEMO

View代码:

 1 @model TsingDa.Ask.Models.UserLogOnModel 2 @{Layout = "";} 3 <script src="http://www.mamicode.com/@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> 4 <script src="http://www.mamicode.com/@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> 5 <script src="http://www.mamicode.com/@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script> 6 <div id="UserLogOnContainer"> 7     @using (Ajax.BeginForm("UserLogOn", "Home", null, 8     new AjaxOptions 9     {10         UpdateTargetId = "UserLogOnContainer",11         HttpMethod = "Post",12         OnSuccess = " ",13     }))14     {15         @Html.ValidationSummary(true)16         <div class="editor-field">17             @Html.TextBoxFor(m => m.Email)18             @Html.ValidationMessageFor(m => m.Email)19         </div>20         <div class="editor-field">21             @Html.TextBoxFor(m => m.Password)22             @Html.ValidationMessageFor(m => m.Password)23         </div>24         <input type="submit" id="logOnBtn" value="http://www.mamicode.com/登陆" />25     }26 </div>

Controller层代码如下:

 1      /// <summary> 2         /// 用户登陆 3         /// </summary> 4         /// <returns></returns> 5         public ActionResult UserLogOn() 6         { 7             return View(new UserLogOnModel("邮箱", "密码")); 8         } 9         [HttpPost]10         public ActionResult UserLogOn(UserLogOnModel entity)11         {12             if (ModelState.IsValid)13             {14                 VM = user_InfoManager.UserLogOn(new User_Info { Email = entity.Email, Password = entity.Password });15                 if (VM.IsComplete)16                 {17                     return RedirectToAction("Index", "Home");18                 }19                 else20                 {21                     VM.ToList().ForEach(i => ModelState.AddModelError("", i));22                 }23             }24 25             return View();26         }

表单提交后,页面效果如下:

需要注意的是,表单中的按钮在异步表单中也是Submit类型,如果是异步表单,引入的JS文件需要有jquery.unobtrusive-ajax.min.js,在这项目的scripts目录已经存在。
