Question

我正在尝试编写一个基于Web的应用程序，该应用程序允许用户在表单字段中输入信息（特别是整数），将输入的信息作为条目添加到.def文件中，运行'.exe'文件（用C ++编写）在文件上，然后在点击“提交”按钮后在屏幕上显示输出。我编写了在JavaScript中运行.exe文件的函数，但它们不起作用。以下是我到目前为止的情况：

输入屏幕包含此代码（HTML文件）：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html><head></head>><body><h1><i>The University of Vermont<br>Department of Medical     Biostatistics<br>Study Randomization Page</i></h1>
<?php
    $study = "study";
    $site = "site";
    $gender = "gender";
    $age = "age";
    $result = "result";
?>

Please Input Your Study Information Below:<br><br>
<form id="form1" action="file:///C:/Documents and Settings/cody/Desktop/DMB_RD_2.php"     method="post">
Study Number:<br>   <input name="study" type="int"><br>
Site Number:<br>    <input name="site" type="int"><br>
Subject Gender:<br> <input name="gender" type="int"><br>
Subject Age:<br>    <input name="age" type="int"><br>
Lab Result:<br>     <input name="result" type="int"><br>
<input value="Submit" class="button" type="submit">
</form>
</body></html>
Here is the page it is connected to (PHP file);
<script type="text/javascript" src="DMB++2JS.js"></script>
<script type="text" src="DMB Round 2.html"></script>
</head>
Here is the information that you input:<br /><br />
Study Number: <?php echo $_POST["study"]; ?><br />
Site Number: <?php echo $_POST["site"]; ?><br />
Subject Gender: <?php echo $_POST["gender"]; ?><br />
Subject Age: <?php echo $_POST["age"]; ?><br />
Lab Result: <?php echo $_POST["result"]; ?><br />
<br />
The following functions will randomize your data. Please indicated which method you would like to use by clicking on the button of the randomization method that you would like to use:<br /><br />
<input type="button" href="blockfn()" onclick="javascript:blockfn(); return     true;">Block Function</button><br />
<input type="button" href="d2rfn()" onclick="javascript:d2rfn(); return true;">Random Distance Function</button><br />
<input type="button" href="d2dfn()" onclick="javascript:d2dfn(); return true;">Determinate Distance Function</button><br />
<input type="button" href="minimizefn()" onclick="javascript:minimizefn(); return true;">Minimization Function</button><br />
<input type="button" href="pocockfn()" onclick="javascript:pocockfn(); return true;">Pocock Function</button><br />
</body>
</html>

这是包含函数的JavaScript文件：

function d2rfn(){
    var oShell = new ActiveXObject("Shell.Application");
    var commandtoRun = "C:\Documents and Settings\cody\Desktop\C++ Programs\D2R001.def"; 
    oShell.ShellExecute(commandtoRun,"","","open","1");
}
function d2dfn(){
    var oShell = new ActiveXObject("Shell.Application");
    var commandtoRun = "C:\Documents and Settings\cody\Desktop\C++ Programs\D2D001.def"; 
    oShell.ShellExecute(commandtoRun,"","","open","1");
}
function minimizefn(){
    var oShell = new ActiveXObject("Shell.Application");
    var commandtoRun = "C:\Documents and Settings\cody\Desktop\C++ Programs\MINIMIZE001.def"; 
    oShell.ShellExecute(commandtoRun,"","","open","1");
}
function pocockfn(){
    var oShell = new ActiveXObject("Shell.Application");
    var commandtoRun = "C:\\Documents and Settings\\cody\\Desktop\\C++ Programs\\POCOCK2001.def"; 
    oShell.ShellExecute(commandtoRun,"","","open","1");
}
//Another possible way of calling the .exe file from the web interface.
var objShell = new ActiveXObject("WScript.Shell");
</script>

最后，我在ASP中编写文件（不起作用）：

<%
    dim Study
    Study=Request.QueryString("Study")
    If Study<>"" Then
      Response.Write(Study)
    End If
    dim Site
    Site=Request.QueryString("Site")
    If Site<>"" Then
      Response.Write(Site)
    End If    
    dim Gender
    Gender=Request.QueryString("Gender")
    If Gender<>"" Then
      Response.Write(Gender)
    End If
    dim Age
    Age=Request.QueryString("Age")
    If Age<>"" Then
      Response.Write(Age)
    End If
    dim Result
    Result=Response.QueryString("Result")
    If Result<>"" Then
      Response.Write(Result)
    End If
%>

有没有人有更简洁的方法来创建这个应用程序？非常感谢。谢谢！

不要这样做。 javascript在客户端计算机上运行，这意味着该程序将在客户端的计算机上运行，并且文件也需要在那里。这违背了拥有Web应用程序的目的。

此外，还有各种非常好的安全原因，不允许浏览器内的javascript运行本地可执行文件 - 如果支持，访问网站可能会导致您的计算机运行，比如format.exe。

首先，选择一个服务器端Web开发框架。不要试图结合PHP＆amp; ASP.NET。其次，弄清楚是否有办法在没有文件系统和命令行实用程序的文件的情况下处理这个问题。您可以在您选择的任何开发框架中执行此逻辑吗？如果你不能，你需要弄清楚如何编写文件，如何shell出来调用.exe以及如何返回结果。这些问题都不是特别棘手，而且我会按顺序一次解决这些问题。

从Web应用程序运行.exe文件
