从javascript运行bat文件 [英] Run a bat file from javascript

问题描述

我正在尝试使用javascript运行bat文件.我已经尝试过使用Powershell，但它似乎无法正常工作.这是我尝试的代码:

I'm trying to run a bat file using javascript. I've tried using powershell but it didn't seem to work properly. Here is the code I tried:

var oShell = WScript.CreateObject("WScript.Shell");
oShell.Exec("D:");
oShell.Exec("cd dir");
oShell.Exec("start user.bat");

我也尝试过:

var oShell = WScript.CreateObject("WScript.Shell");
oShell.Exec("start D:\dir\user.bat");

有时它运行，有时会出现错误预期的十六进制数字"，访问被拒绝". 我真的很困惑我要做的就是从javascript文件执行bat文件.

Sometimes it runs, sometimes I get those errors "Expected hexadecimal digit", "Access is denied". I'm really confused. All I'm trying to do is execute a bat file from a javascript file.

任何人都知道该怎么做吗?谢谢！

Anyone has any idea how to do it? Thank you!

推荐答案

首先，JavaScript没有任何操作系统服务.因此，您实际上指的是恰巧是用JavaScript编写的Windows脚本宿主(WSH)脚本.

First, JavaScript doesn't have any operating system services. So you are really referring to a Windows Script Host (WSH) script that happens to be written in JavaScript.

第二，start不是可执行文件，而是内置在cmd.exe中的命令.

Second, start is not an executable but rather a command that is built into cmd.exe.

混乱不堪，听起来您想从WSH脚本执行Shell脚本(批处理文件).最简单的方法是这样的(这与您已经尝试过的方法有些接近):

With the confusion out of the way, it sounds like you want to execute a shell script (batch file) from a WSH script. The simplest way is like this (this is somewhat close to what you tried already):

var wshShell = new ActiveXObject("WScript.Shell");
wshShell.Run("D:\\dir\\user.bat");

要创建WshShell COM对象引用(progid WScript.Shell)，请使用new关键字和ActiveXObject构造函数.另外，由于\会转义JavaScript字符串中的字符，因此您需要将JavaScript字符串中的反斜杠(\)加倍.

To create the WshShell COM object reference (progid WScript.Shell), use the new keyword and the ActiveXObject constructor. Also, you need to double your backslashes (\) in JavaScript strings because \ escapes characters in JavaScript strings.
