如何使用电子获取文件夹路径

问题描述

我对电子很陌生.谁能建议我如何使用电子获取本地文件夹的相对路径?JavaScript 没有这种能力.

I am very new to the electron. Can anyone suggest me how to get a local folder's relative path using the electron? JavaScript does not have that capability.

我有一个选择文件按钮(见快照)，所以我的问题是当我选择一个文件夹并单击打开按钮时，它应该返回一个完整的目录路径.

I have a Choose File button(see snapshot), so my question is that when I select a folder and click on the open button then it should return a whole directory path.

推荐答案

正如@phuongle 在评论中指出的，你想使用 showOpenDialog().像这样的:

As @phuongle pointed out in the comments you want to use showOpenDialog(). Something like this:

var remote = require('remote');
var dialog = remote.require('electron').dialog;

var path = dialog.showOpenDialog({
    properties: ['openDirectory']
});

更新:如果上述方法不适用于您当前的 Electron 版本，您应该尝试更现代的导入:

UPDATE: If the above isn't working for your current Electron version, you should try more modern importing:

const {dialog} = require('electron').remote;

另外，为了使用remote，你需要在主进程中创建窗口时设置enableRemoteModule:

In addition, in order to use remote, you need to set enableRemoteModule when creating your window in your main process:

const myWindow = new BrowserWindow({
    webPreferences: {
        enableRemoteModule: true
    }
});
