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。

你可以这样写:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="button" value="Send" />
<input type="submit" name="button" value="Cancel" />
<% Html.EndForm(); %>

然后在页面中检查name == "Send"或者name == "Cancel"…

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();
}

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()。

如果您的浏览器支持输入按钮的属性格式操作(IE 10+,不确定其他浏览器),那么以下应该工作:

@using (Html.BeginForm()){
    //put form inputs here

<input id="sendBtn" value="Send" type="submit" formaction="@Url.Action("Name Of Send Action")" />

<input id="cancelBtn" value="Cancel" type="submit" formaction="@Url.Action("Name of Cancel Action") />

}

给你的提交按钮一个名字,然后在你的控制器方法中检查提交的值:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="submitButton" value="Send" />
<input type="submit" name="submitButton" value="Cancel" />
<% Html.EndForm(); %>

发布到

public class MyController : Controller {
    public ActionResult MyAction(string submitButton) {
        switch(submitButton) {
            case "Send":
                // delegate sending to another controller action
                return(Send());
            case "Cancel":
                // call another action to perform the cancellation
                return(Cancel());
            default:
                // If they've submitted the form without a submitButton, 
                // just return the view again.
                return(View());
        }
    }

    private ActionResult Cancel() {
        // process the cancellation request here.
        return(View("Cancelled"));
    }

    private ActionResult Send() {
        // perform the actual send operation here.
        return(View("SendConfirmed"));
    }

}

编辑:

要将此方法扩展到本地化站点,请将您的消息隔离在其他地方(例如将资源文件编译为强类型资源类)

然后修改代码,使其像这样工作:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="submitButton" value="<%= Html.Encode(Resources.Messages.Send)%>" />
<input type="submit" name="submitButton" value="<%=Html.Encode(Resources.Messages.Cancel)%>" />
<% Html.EndForm(); %>

你的控制器应该是这样的:

// Note that the localized resources aren't constants, so 
// we can't use a switch statement.

if (submitButton == Resources.Messages.Send) { 
    // delegate sending to another controller action
    return(Send());

} else if (submitButton == Resources.Messages.Cancel) {
     // call another action to perform the cancellation
     return(Cancel());
}

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") %>
