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。

//model
public class input_element
{
public string Btn { get; set; }
}
//views--submit btn can be input type also...
@using (Html.BeginForm())
{
<button type="submit" name="btn" value="verify">
Verify data</button>
<button type="submit" name="btn" value="save">
Save data</button>
<button type="submit" name="btn" value="redirect">
Redirect</button>
}
//controller
public ActionResult About()
{
ViewBag.Message = "Your app description page.";
return View();
}
[HttpPost]
public ActionResult About(input_element model)
{
if (model.Btn == "verify")
{
// the Verify button was clicked
}
else if (model.Btn == "save")
{
// the Save button was clicked
}
else if (model.Btn == "redirect")
{
// the Redirect button was clicked
}
return View();
}

以下是最适合我的方法:
<input type="submit" value="Delete" name="onDelete" />
<input type="submit" value="Save" name="onSave" />
public ActionResult Practice(MyModel model, string onSave, string onDelete)
{
if (onDelete != null)
{
// Delete the object
...
return EmptyResult();
}
// Save the object
...
return EmptyResult();
}
我已经为HtmlHelper创建了一个ActionButton方法。它将在OnClick事件中生成带有javascript的普通输入按钮,将表单提交给指定的控制器/动作。
像这样使用辅助器
@Html.ActionButton("MyControllerName", "MyActionName", "button text")
这将生成以下HTML
<input type="button" value="button text" onclick="this.form.action = '/MyWebsiteFolder/MyControllerName/MyActionName'; this.form.submit();">
下面是扩展方法代码:
VB。网
<System.Runtime.CompilerServices.Extension()>
Function ActionButton(pHtml As HtmlHelper, pAction As String, pController As String, pRouteValues As Object, pBtnValue As String, pBtnName As String, pBtnID As String) As MvcHtmlString
Dim urlHelperForActionLink As UrlHelper
Dim btnTagBuilder As TagBuilder
Dim actionLink As String
Dim onClickEventJavascript As String
urlHelperForActionLink = New UrlHelper(pHtml.ViewContext.RequestContext)
If pController <> "" Then
actionLink = urlHelperForActionLink.Action(pAction, pController, pRouteValues)
Else
actionLink = urlHelperForActionLink.Action(pAction, pRouteValues)
End If
onClickEventJavascript = "this.form.action = '" & actionLink & "'; this.form.submit();"
btnTagBuilder = New TagBuilder("input")
btnTagBuilder.MergeAttribute("type", "button")
btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript)
If pBtnValue <> "" Then btnTagBuilder.MergeAttribute("value", pBtnValue)
If pBtnName <> "" Then btnTagBuilder.MergeAttribute("name", pBtnName)
If pBtnID <> "" Then btnTagBuilder.MergeAttribute("id", pBtnID)
Return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal))
End Function
c# (c#代码只是从VB DLL中反编译的,所以它可以得到一些美化…但是时间太短了:-)
public static MvcHtmlString ActionButton(this HtmlHelper pHtml, string pAction, string pController, object pRouteValues, string pBtnValue, string pBtnName, string pBtnID)
{
UrlHelper urlHelperForActionLink = new UrlHelper(pHtml.ViewContext.RequestContext);
bool flag = Operators.CompareString(pController, "", true) != 0;
string actionLink;
if (flag)
{
actionLink = urlHelperForActionLink.Action(pAction, pController, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
}
else
{
actionLink = urlHelperForActionLink.Action(pAction, System.Runtime.CompilerServices.RuntimeHelpers.GetObjectValue(pRouteValues));
}
string onClickEventJavascript = "this.form.action = '" + actionLink + "'; this.form.submit();";
TagBuilder btnTagBuilder = new TagBuilder("input");
btnTagBuilder.MergeAttribute("type", "button");
btnTagBuilder.MergeAttribute("onClick", onClickEventJavascript);
flag = (Operators.CompareString(pBtnValue, "", true) != 0);
if (flag)
{
btnTagBuilder.MergeAttribute("value", pBtnValue);
}
flag = (Operators.CompareString(pBtnName, "", true) != 0);
if (flag)
{
btnTagBuilder.MergeAttribute("name", pBtnName);
}
flag = (Operators.CompareString(pBtnID, "", true) != 0);
if (flag)
{
btnTagBuilder.MergeAttribute("id", pBtnID);
}
return MvcHtmlString.Create(btnTagBuilder.ToString(TagRenderMode.Normal));
}
这些方法具有各种参数,但是为了便于使用,您可以创建一些重载,只使用所需的参数。
David Findley在他的ASP上写了3种不同的选择。网络博客。
阅读文章的多个按钮以相同的形式查看他的解决方案,以及每个方案的优缺点。恕我直言,他提供了一个非常优雅的解决方案,利用属性,你装饰你的行动。
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()。
当使用ajax表单时,我们可以使用ActionLinks与POST HttpMethod和 在AjaxOptions中序列化表单。OnBegin事件。
假设你有两个动作,InsertAction和UpdateAction:
<form>
@Html.Hidden("SomeField", "SomeValue")
@Ajax.ActionLink(
"Insert",
"InsertAction",
null,
new AjaxOptions {
OnBegin = "OnBegin",
UpdateTargetId = "yourDiv",
HttpMethod = "POST" })
@Ajax.ActionLink(
"Update",
"UpdateAction",
null,
new AjaxOptions {
OnBegin = "OnBegin",
UpdateTargetId = "yourDiv",
HttpMethod = "POST" })
</form>
Javascript
function OnBegin(xhr, settings) {
settings.data = $("form").serialize();
}
