ASP.NET MVC 3.0小知识积累

1、JsonResult

 1 using System.Web.Mvc;
 2 
 3 //public ActionResult Index()
 4 public JsonResult Index()
 5 {
 6     var province = from p in new Models.NorthwindDataContext().Province
 7                     select p;
 8 
 9     return Json(new
10         {
11             page = 1,
12             total = province.Count(),
13             rows = province.ToList()
14         },
15         JsonRequestBehavior.AllowGet
16     );
17 }

2、Html Helper

@Html.TextBox("UserName") <—> <input id="UserName" type="text" value="" name="UserName">

@Html.TextBox("UserName", null, new { id = "txtUserName" }) <—> <input id="txtUserName" type="text" value="" name="UserName">
@Html.TextBox("UserName", null, new { id = "txtUserName", style = "100px;" }) <—> <input id="txtUserName" type="text" value="" style="100px;" name="UserName">

@Html.TextBox("UserName", null, new { id = "txtUserName", @class = "highlight" }) <—> <input id="txtUserName" class="highlight" type="text" value="" name="UserName">

@Html.ActionLink("删除", "DeletePost", new { id = item.ID }, new { onclick = "return confirm('你确定要删除该随笔?')" })
