MVC剃刀按钮 [英] MVC Razor Buttons

问题描述

您好，我是新来的MVC剃刀

Hi i am new to MVC Razor

我试图做一个页面3按钮插入，删除和更新。

I was trying to do a page with 3 Button insert,delete and update.

我的观点看起来像

        <div>    
          @using (Html.BeginForm())
           {

                <input type="button" class="button1" value="Insert" />
                <input type="button" class="button1" value="Delete" />
                <input type="button" class="button1" value="Update" /> 
           }
        </div>

和我的控制器就像

       public ActionResult Index()
       {
              return View();
       }

我怎样才能得到这些按钮的事件在我的控制器，这样我就能写出逻辑为每个按钮。请帮我获得的编码或任何合适的链接，这将有助于解决这一问题。

How i will get the events of these button in my controller so that i will be able to write the logic for each button. Please help me to get the coding or any suitable link which will help to solve this problem.

谢谢
圣

推荐答案

重新itterate在其他答案的评论我的观点：当您绑定的逻辑在C＃中你是你的C＃code绑定到该语言的按钮的值。

to re-itterate my point in the comments on the other answers: when you BIND LOGIC to the VALUE of a BUTTON in C# you are binding your C# code to that language.

想象一下，你在英文版本的保存按钮：

Imagine you have the Save button in the english version as:

<input type="submit" value="Insert" name='button' />

和在你的code你会使用值来切换：

and in your code you are going to switch using the value:

public ActionResult Index(string button)
{
    switch (button)  
    {
        case "Insert": ...
        case "Update": ...
        case "Delete": ...       
    }

    return View();
}

现在 - 当这种形式在另一种语言查看 - 你觉得什么会发生。

Now - when that form is viewed in another language - what do you think will happen?!?!

这里是威尔士HTML输出：

here is the welsh html output:

<input type="submit" value="Mewnosod" name='button' />

和德国的：

<input type="submit" value="Einfügen" name='button' />

这怎么EVER去上班？！

How is that EVER going to work?!

全球化不是一个单独的发行!!!!

Globalization IS NOT A SEPERATE ISSUE!!!!

你的行动看起来像这样如果你使用这个方法：

your action will look like this if you use this method:

public ActionResult Index(string button)
{
    switch (button)  
    {
        case "Insert": ...
        case "Update": ...
        case "Delete": ...     
        case "Einfügen": ...  
        case "Mewnosod": ....
        .... a load of other languages for each action type - 
    }

    return View();
}

请认真... ....

please... seriously....

下面是我的MVC的行动选择code：的 Asp.Net的mvc动作选择

Here's my MVC Action Selector code: Asp.Net Mvc action selector

在本质上你需要一个动作选择器类：

In essence you need an action selector class:

/// <summary>
/// AcceptParameterAttribute to enable submit buttons to execute specific action methods.
/// </summary>
public class AcceptParameterAttribute : ActionMethodSelectorAttribute
{
    /// <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>
    /// 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");
        }
 
        var req = controllerContext.RequestContext.HttpContext.Request;
 
        return req.Form.AllKeys.Contains(this.Action);
 
    }
}

这工作了你给该按钮的名称。

Which works off the name you give the button.

您可以再与装饰动作：

[AcceptParameter(Action = "Edit")]
public ActionResult Person_Edit(PersonViewModel model){
...
}

开关在动作脏 - 这是一个更清洁的方式。我觉得更自然了。

Switching in the action is dirty - this is a much cleaner approach. I think much more natural too.
