如何使用电子中的按钮打开exe文件 [英] How can i open an exe file using a button inElectron

问题描述

我正在尝试使按钮在计算机中打开exe文件，但无法打开，并且出现此错误

I am trying to make a button open an exe file in computer but it doesn't open and it gives me this error

未捕获的ReferenceError：在runExe（main.js：61）处未定义
在HTMLButtonElement.onclick处的

Uncaught ReferenceError: require is not defined at runExe (main.js:61) at HTMLButtonElement.onclick

这是我的按钮的代码

<button onclick="runExe()" id="button">click</button>

我从互联网上获得了此代码，当我删除函数runExe（）时，exe文件打开当我启动该应用程序并且希望它仅在单击按钮时打开。

and i got this code form the internet and when i remove the function runExe() the exe file opens when i start the app and i want it to only open when button is clicked.

这是打开exe文件的代码

here is the code to open the exe file

function runExe(){
var child = require('child_process').execFile;
var executablePath = "winRAR.exe";

child(executablePath, function(err, data) {
  if(err){
 console.error(err);
  return;
}


console.log(data.toString());
});}

推荐答案

错误消息提示您不能使用 require 。

The error message says you cannot use require.

您正在尝试在渲染器进程中运行该代码。如果main和renderer之间的区别是新的，请参见 https ：//www.electronjs.org/docs/tutorial/application-architecture#main-and-renderer-processes

You are trying to run that code in the renderer process. If the distinction between main and renderer is new, see https://www.electronjs.org/docs/tutorial/application-architecture#main-and-renderer-processes

一种做自己想要的方法相反，是让呈现的流程将打开的请求发送到主流程，在该流程中，需求将在其中运行，在哪个子流程应该在其中打开。

One way to do what you want is to instead have the rendered process send the open request to the main process, where the require will work, and where opening a child process should work.

BTW，我不知道不知道 shell.openItem（）（ https://www.electronjs.org/docs/api/shell ）可用于启动任何exe吗？如果是这样，那可能是更好的方法。

BTW, I don't know if shell.openItem() (https://www.electronjs.org/docs/api/shell) can be used to start any exe? If so, that might be the better way to do it.
