是否有一些简单的方法来处理来自同一个表单的多个提交按钮?例如:
<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" value="Send" />
<input type="submit" value="Cancel" />
<% Html.EndForm(); %>
知道如何在ASP中做到这一点吗?NET框架测试版?我在谷歌上搜索的所有例子中都有单个按钮。

如果你对HTML 5的使用没有限制,你可以使用带有formaction的<button>标签:
<form action="demo_form.asp" method="get">
First name: <input type="text" name="fname" /><br />
Last name: <input type="text" name="lname" /><br />
<button type="submit">Submit</button><br />
<button type="submit" formaction="demo_admin.asp">Submit as admin</button>
</form>

使用自定义助手(创建一个“Helpers.”文件)。cshtml" App_Code文件夹内,在你的项目的根)用javascript重写(在一个'onclick'事件)表单的'动作'属性,你想要的东西,然后提交它。
助手可以是这样的:
@helper SubmitButton(string text, string controller,string action)
{
var uh = new System.Web.Mvc.UrlHelper(Context.Request.RequestContext);
string url = @uh.Action(action, controller, null);
<input type=button onclick="(
function(e)
{
$(e).parent().attr('action', '@url'); //rewrite action url
//create a submit button to be clicked and removed, so that onsubmit is triggered
var form = document.getElementById($(e).parent().attr('id'));
var button = form.ownerDocument.createElement('input');
button.style.display = 'none';
button.type = 'submit';
form.appendChild(button).click();
form.removeChild(button);
}
)(this)" value="@text"/>
}
然后把它用作:
@Helpers.SubmitButton("Text for 1st button","ControllerForButton1","ActionForButton1")
@Helpers.SubmitButton("Text for 2nd button","ControllerForButton2","ActionForButton2")
...
在你的表单里面。
这个脚本允许指定一个data-form-action属性,它将在所有浏览器中作为HTML5 formaction属性(以一种不引人注目的方式):
$(document).on('click', '[type="submit"][data-form-action]', function(event) {
var $this = $(this),
var formAction = $this.attr('data-form-action'),
$form = $($this.closest('form'));
$form.attr('action', formAction);
});
包含按钮的表单将被发送到data-form-action属性中指定的URL:
<button type="submit" data-form-action="different/url">Submit</button>
这需要jQuery 1.7。对于以前的版本,您应该使用live()而不是on()。
您可以像前面提到的那样检查动作中的名称,但是您可能会考虑这是否是好的设计。考虑动作的职责,不要将这种设计过多地与按钮名称等UI方面结合起来,这是一个好主意。所以考虑使用两种形式和两种动作:
<% Html.BeginForm("Send", "MyController", FormMethod.Post); %>
<input type="submit" name="button" value="Send" />
<% Html.EndForm(); %>
<% Html.BeginForm("Cancel", "MyController", FormMethod.Post); %>
<input type="submit" name="button" value="Cancel" />
<% Html.EndForm(); %>
此外,在“取消”的情况下,您通常只是不处理表单,而是转到一个新的URL。在这种情况下,你根本不需要提交表单,只需要一个链接:
<%=Html.ActionLink("Cancel", "List", "MyController") %>
这是我发现的最好的方法:

代码如下:
/// <summary>
/// ActionMethodSelector to enable submit buttons to execute specific action methods.
/// </summary>
public class AcceptParameterAttribute : ActionMethodSelectorAttribute
{
/// <summary>
/// Gets or sets the value to use to inject the index into
/// </summary>
public string TargetArgument { get; set; }
/// <summary>
/// Gets or sets the value to use in submit button to identify which method to select. This must be unique in each controller.
/// </summary>
public string Action { get; set; }
/// <summary>
/// Gets or sets the regular expression to match the action.
/// </summary>
public string ActionRegex { get; set; }
/// <summary>
/// Determines whether the action method selection is valid for the specified controller context.
/// </summary>
/// <param name="controllerContext">The controller context.</param>
/// <param name="methodInfo">Information about the action method.</param>
/// <returns>true if the action method selection is valid for the specified controller context; otherwise, false.</returns>
public override bool IsValidForRequest(ControllerContext controllerContext, MethodInfo methodInfo)
{
if (controllerContext == null)
{
throw new ArgumentNullException("controllerContext");
}
Func<NameValueCollection> formGetter;
Func<NameValueCollection> queryStringGetter;
ValidationUtility.GetUnvalidatedCollections(HttpContext.Current, out formGetter, out queryStringGetter);
var form = formGetter();
var queryString = queryStringGetter();
var req = form.AllKeys.Any() ? form : queryString;
if (!string.IsNullOrEmpty(this.ActionRegex))
{
foreach (var key in req.AllKeys.Where(k => k.StartsWith(Action, true, System.Threading.Thread.CurrentThread.CurrentCulture)))
{
if (key.Contains(":"))
{
if (key.Split(':').Count() == this.ActionRegex.Split(':').Count())
{
bool match = false;
for (int i = 0; i < key.Split(':').Count(); i++)
{
if (Regex.IsMatch(key.Split(':')[0], this.ActionRegex.Split(':')[0]))
{
match = true;
}
else
{
match = false;
break;
}
}
if (match)
{
return !string.IsNullOrEmpty(req[key]);
}
}
}
else
{
if (Regex.IsMatch(key, this.Action + this.ActionRegex))
{
return !string.IsNullOrEmpty(req[key]);
}
}
}
return false;
}
else
{
return req.AllKeys.Contains(this.Action);
}
}
}
享受一个没有代码气味的多提交按钮的未来。
