ASP.NET MVC下Ajax.BeginForm方式无刷新提交表单实例
2020-11-27
来源：爱问旅游网
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 {
UpdateTargetId = "updateHolder",
OnBegin = "DeliverableEdit.onBegin",
OnFailure = "DeliverableEdit.onFailure",
OnSuccess = "DeliverableEdit.onSuccess",
OnComplete = "DeliverableEdit.onComplete",
HttpMethod = "Post"
};
}
@using ( Ajax.BeginForm("Save", "DesignDeliverable", null, ajaxOptions, new { @class = "form-horizontal", id = "editForm" }) ) {
