ASP.NET MVC下Ajax.BeginForm方式无刷新提交表单实例

有时候，不得不考虑到以下场景问题：

数据库表字段会频繁更改扩展，而流行的重业务的js框架过于依赖json数据接口，导致的问题是，数据库表更改 -> 数据接口更改 -> 前段框架逻辑更改。。。

一不小心就陷入坑坑洼洼。

这样的话，原来纯asp.net mvc绑定的方式，还是可以一用的，因为该方式不用再为那么多js代码烦恼。

不好意思，前面自说自话啊，直接上干货代码了————

ajax.beginform

@{
 layout = null;
 var ajaxoptions = new ajaxoptions {

  onbegin = "deliverableedit.onbegin",

  onsuccess = "deliverableedit.onsuccess",
  oncomplete = "deliverableedit.oncomplete",
  httpmethod = "post"
 };
}
