ASP.NET MVC下Ajax.BeginForm方式无刷新提交表单实例

发布时间：2020-12-15 20:03:51 所属栏目：asp.Net 来源：网络整理

导读：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，

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

后端代码――――

[Route("~/DesignDeliverable/Edit/{id?}")]
  [HttpGet]
  public ActionResult Edit(Guid? id) {
   using ( EmpsDbContext db = new EmpsDbContext() ) {
    DesignDeliverable entity = null;
    if ( id.HasValue ) {
