1、指定表单提交方式和路径等
@using (Html.BeginForm("Index", "Home", FormMethod.Get, new { name = "nbform", id = "nbform" }))
2、指定表单提交为数据方式
@using (Html.BeginForm("ImportExcel", "Stock", FormMethod.Post, new { enctype = "multipart/form-data" }))
注意， 有时候要加{id=1}不然在点击超过第一页的索引时form后面会自动加上当前页的索引，如果此时再搜索则可能会出来“超出索引值”的错误提示
@using (Html.BeginForm("Index", null, new { id = 1 }, FormMethod.Get))
3、下面的操作可以防止提交链接后面自带参数
@using (Html.BeginForm("AddDIYBillOfLading", "BillOfLading", new { id ="" }, FormMethod.Post, new { name = "myform", id = "myform" }))
即，RouteValues的id=""
二、Ajax.BeginForm()
@using (Ajax.BeginForm("Search", new RouteValueDictionary { { "id", "" } },
new AjaxOptions { UpdateTargetId = "ListData", HttpMethod = "Get", InsertionMode = InsertionMode.Replace },
new RouteValueDictionary { { "id", "searchForm" } }))
{……}注释：创建了一个ajax的表单，其中动作是Search，参数id是""，http请求的方法是Get，插入方式是替换（如果你做的是瀑布流，还可以用追加），这个表单本身的id是searchForm
1 @using (Ajax.BeginForm(
2 new AjaxOptions
3 {
4 UpdateTargetId = "UserLogOnContainer",
5 HttpMethod = "Post",
6 OnSuccess = " ",
7 })){} //提交到当前页面，提交方式为Post,异步更新模块ＩＤ为UserLogOnContainer
8
9 @using (Ajax.BeginForm("action", "controller", null,
10 new AjaxOptions
11 {
12 UpdateTargetId = "UserLogOnContainer",
13 HttpMethod = "Post",
14 OnSuccess = " ",
15 }))
16 {} //提交到指定controller下的action，提交方式为Post,异步更新模块ＩＤ为UserLogOnContainer
Html.BeginForm())与Ajax.BeginForm()
