在单击两个不同的按钮时将相同的参数传递给操作 [英] Passing same parameter to an action on clicking two different buttons

问题描述

我有一个显示文件名列表的视图.我也有两个按钮，分别是 View 和 Release .当我从列表中选择一个文件名并单击视图时，它会导航到适当的操作方法以及作为参数选择的文件名，并根据需要执行功能.

I have a View which displays a list of file names. Also i have two buttons called View and Release. When I select a file name from the list and click on view, it navigates to the appropriate action method along with the file name selected as a parameter and performs the functionality as required.

但是当我选择文件名后单击 Release 时，它会导航到适当的操作方法，但没有将文件名作为参数传递给操作方法.它显示为 null .

But when i click on Release after selecting a file name, it does navigates to the appropriate action method, but does not passes the file name as a parameter to the action method. It shows as null.

请注意， View 和 Release 指向具有不同操作方法的单个控制器.

Please note that View and Release directs to a single controller having different action methods.

单击发布时，如何获取文件名作为参数?

How can i get to pass the filename as a parameter when i click on release?

请参见下面的代码:

public class HoldFilesController : Controller
{
    // GET: HoldFiles
    string holdpath = ConfigurationManager.AppSettings["HoldPath"].ToString();
    public ActionResult Index()
    {       
        DirectoryInfo dirInfo = new DirectoryInfo(holdpath);

        List<FileInfo> files = dirInfo.GetFiles().ToList();

        return View("Index",files);
    }
}

[HttpPost] 
public ActionResult ViewFile(string[] Name)
{
    byte[] ImageData = null;
    for (int i = 0; i < Name.Length; i++)
    {
        string filepath = holdpath + @"\" + Name[i];

        FileStream fs = new FileStream(filepath, FileMode.Open, 
        FileAccess.ReadWrite);

        ImageData = new byte[fs.Length];
        fs.Read(ImageData, 0, System.Convert.ToInt32(fs.Length));

        fs.Close();
    }
    return File(ImageData,"application/pdf");
}

[HttpPost]
public ActionResult ReleaseFile(string[] Name)
{
    for(int i=0; i<Name.Length;i++)
    {

        string sourcefilepath= holdpath + @"\" + Name[i];
        string Destinationfilepath = 
            ConfigurationManager.AppSettings["ReleaseFolderPath"].ToString();
        string ReleaseFilePath = Destinationfilepath + @"\" + Name[i];
        if (Directory.Exists(Destinationfilepath))
        {
            System.IO.File.Move(sourcefilepath, ReleaseFilePath);
        }
    }
    return RedirectToAction("Index");
}

这是我的视图的代码:

@model IEnumerable<FileInfo>
@{
    ViewBag.Title = "files";
}

<h2>Held files</h2>
@using (Html.BeginForm())
{
    <div style="border:solid;width:100%;overflow-x:auto;">
        <table  align="center" style="width:100%">
            <thead>
                <tr>
                    <th>File Name</th>
                    <th>Action</th>
                </tr>
            </thead>
            <tbody>
                @foreach (FileInfo file in Model)
                {
                    <tr>
                        <td>
                            <input type="checkbox" name="Name" value="@file.Name" />
                            @file.Name
                        </td>
                    </tr>
                }
            </tbody>
        </table>
   </div>
    <input type="submit" id="Held" name="Held file" value="View" />
    <input type="submit" id="Release" name="release" value="Release" />
}

为避免混淆， View 按钮重定向到 ViewFile 方法然后 Release 按钮重定向到 Releasefile 方法.

Just to avoid confusion, the View button redirects to the ViewFile method and the Release button redirects to Releasefile method.

推荐答案

1-HTML5格式和格式方法属性

 <input type="submit" name="view" value="view" formaction="ViewFile" formmethod="post" />

<input type="submit" name="Release" value="Release" formaction="ReleaseFile" formmethod="post" />

2-jQuery/JavaScript代码

$(document).ready(function () {

    $("#Held").click(function () {
        $("form").attr("action", "/HoldFiles/ViewFile");
    });

    $("#Release").click(function () {
        $("form").attr("action", "/HoldFiles/ReleaseFile");
    });
});
