[英]Electron : using showOpenDialog allows files to be chosen on Linux & Win10 but why can't I choose file on MacOS?
I'm using the following code (with great success on Linux and Win10) to select a file (and ultimately read its contents).我正在使用以下代码(在 Linux 和 Win10 上取得了巨大成功)到 select 一个文件(并最终读取其内容)。
This is in my main.js and pops up a dialog on Linux and Win10 and allows me to choose a file.这是在我的 main.js 中,并在 Linux 和 Win10 上弹出一个对话框,并允许我选择一个文件。
ipc.on('open-file-dialog', function (event) {
dialog.showOpenDialog({
properties: ['openFiles'],
defaultPath: specialFoldersPath,
}, function (files) {
if (files) event.sender.send('selected-file', files)
})
})
The code pops up the file open dialog on MacOS too, however, on my Mac Mini running MacOS Mojave v10.14.6 I see the following:该代码也会在 MacOS 上弹出文件打开对话框,但是,在运行 MacOS Mojave v10.14.6 的 Mac Mini 上,我看到以下内容:
Notice that I can select a folder but I cannot select any files (they are greyed out and disabled).请注意,我可以select 一个文件夹,但我不能 select 任何文件(它们是灰色和禁用的)。
I've examined the options at https://electronjs.org/docs/api/dialog but I don't see any additional option that needs to be set for MacOS to allow files to be selected.我已经检查了https://electronjs.org/docs/api/dialog中的选项,但我没有看到需要为 MacOS 设置任何其他选项以允许选择文件。 Do you know why this is occurring?
你知道为什么会这样吗?
Note : As I was writing this up, I noticed something with the code that ended up being the solution.注意:当我写这篇文章时,我注意到代码中的一些东西最终成为了解决方案。 However, since SO says you can post an answer a question that hasn't been asked and because this is an interesting problem I decided to post and answer.
但是,由于 SO 说您可以发布一个尚未被问到的问题的答案,并且因为这是一个有趣的问题,所以我决定发布并回答。
After staring at the documentation for quite a while I noticed the problem.在盯着文档很长一段时间后,我注意到了这个问题。 It was very subtle.
这是非常微妙的。 Here's the important part from the documentation:
这是文档中的重要部分:
Oops!哎呀! The properties value is
openFile
not openFile s .属性值是
openFile
而不是 openFile s 。
The red herring was the fact that this did work properly (with the wrong property value) on Linux and Win10.红鲱鱼的事实是,这在 Linux 和 Win10 上确实可以正常工作(使用错误的属性值)。
Here is the fixed code:这是固定代码:
ipc.on('open-file-dialog', function (event) {
dialog.showOpenDialog({
properties: ['openFile'],
defaultPath: specialFoldersPath,
}, function (files) {
if (files) event.sender.send('selected-file', files)
})
})
