jquery ajax/post/get 传参数给 mvc的action
1.ActionResult Test1
2.View Test1.aspx
3.ajax page
4.MetaObjectMigration.cs string json convert to class
5.相关的代码下载（包含用的相关类， jquery.json.js等）
ActionResult Test1
public ActionResult Test1(string nameJS, UserInfoInputData model, string js)
{
UserInfoInputData userinfo = new UserInfoInputData();
if (!string.IsNullOrEmpty(js))
{
userinfo = (UserInfoInputData)js.ToInputDataObject(typeof(UserInfoInputData));
} ViewData["Time"] = model.Name + " :" + userinfo.Name;
ViewData["Time2"] = model.age;
ViewData["Message"] = "Test1 :" + nameJS + " :" + typeof(UserInfoInputData).ToString(); ViewData["js"] = userinfo.ToJSON(); return View();
}
