显示用于打开和保存文件、警报等的本机系统对话框。

线程：主线程

显示用于选择多个文件和目录的对话框的示例:

const { dialog } = require('electron')
console.log(dialog.showOpenDialog({ properties: ['openFile', 'openDirectory', 'multiSelections'] }))

这个对话框是从Electron的主线程上打开的。如果要使用渲染器进程中的对话框对象, 可以使用remote来获得:

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

dialog

Display native system dialogs for opening and saving files, alerting, etc.

Process: Main

An example of showing a dialog to select multiple files and directories:

const { dialog } = require('electron')
console.log(dialog.showOpenDialog({ properties: ['openFile', 'openDirectory', 'multiSelections'] }))

The Dialog is opened from Electron's main thread. If you want to use the dialog object from a renderer process, remember to access it using the remote:

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

方法

dialog 模块具有以下方法:

Methods

The dialog module has the following methods:

dialog.showOpenDialogSync([browserWindow, ]options)

  • browserWindow BrowserWindow (可选)

  • 选项 Object

    • title String (可选)
    • defaultPath String (可选)
    • buttonLabel String (可选) - 「确认」按钮的自定义标签, 当为空时, 将使用默认标签。
    • filters FileFilter[] (可选)

    • properties String -包含对话框应用的功能。支持以下值:

      • openFile - 允许选择文件
      • openDirectory - 允许选择文件夹
      • multiSelections-允许多选。
      • showHiddenFiles-显示对话框中的隐藏文件。
      • createDirectory macOS -允许你通过对话框的形式创建新的目录。
      • promptToCreate Windows-如果输入的文件路径在对话框中不存在, 则提示创建。 这并不是真的在路径上创建一个文件，而是允许返回一些不存在的地址交由应用程序去创建。
      • noResolveAliases macOS -禁用自动别名 (symlink) 路径解析。 选定的别名现在将返回别名路径而不是其目标路径。
      • treatPackageAsDirectory macOS -将包 (如 .app 文件夹) 视为目录而不是文件。
    • message String (可选) macOS -显示在输入框上方的消息。
    • securityScopedBookmarks Boolean (可选) masOS mas - 在打包提交到Mac App Store时创建 security scoped bookmarks

browserWindow 参数允许该对话框将自身附加到父窗口, 作为父窗口的模态框。

filters 指定一个文件类型数组，用于规定用户可见或可选的特定类型范围。例如:

{
  filters: [
    { name: 'Images', extensions: ['jpg', 'png', 'gif'] },
    { name: 'Movies', extensions: ['mkv', 'avi', 'mp4'] },
    { name: 'Custom File Type', extensions: ['as'] },
    { name: 'All Files', extensions: ['*'] }
  ]
}

extensions 数组应为没有通配符或点的扩展名 (例如, "png" 是正确的, 而 ".png" 和 *. png " 就是错误的)。 若要显示所有文件, 请使用 "*" 通配符 (不支持其他通配符)。

注意: 在 Windows 和 Linux 上, 打开对话框不能同时是文件选择器和目录选择器, 因此如果在这些平台上将 properties 设置为["openFile"、"openDirectory"], 则将显示为目录选择器。

dialog.showOpenDialogSync(mainWindow, {
  properties: ['openFile', 'openDirectory']
})

dialog.showOpenDialogSync([browserWindow, ]options)

  • browserWindow BrowserWindow (optional)

  • options Object

    • title String (optional)
    • defaultPath String (optional)
    • buttonLabel String (optional) - Custom label for the confirmation button, when left empty the default label will be used.
    • filters FileFilter[] (optional)

    • properties String - Contains which features the dialog should use. The following values are supported:

      • openFile - Allow files to be selected.
      • openDirectory - Allow directories to be selected.
      • multiSelections - Allow multiple paths to be selected.
      • showHiddenFiles - Show hidden files in dialog.
      • createDirectory macOS - Allow creating new directories from dialog.
      • promptToCreate Windows - Prompt for creation if the file path entered in the dialog does not exist. This does not actually create the file at the path but allows non-existent paths to be returned that should be created by the application.
      • noResolveAliases macOS - Disable the automatic alias (symlink) path resolution. Selected aliases will now return the alias path instead of their target path.
      • treatPackageAsDirectory macOS - Treat packages, such as .app folders, as a directory instead of a file.
    • message String (optional) macOS - Message to display above input boxes.
    • securityScopedBookmarks Boolean (optional) masOS mas - Create security scoped bookmarks when packaged for the Mac App Store.

Returns String[] | undefined, the file paths chosen by the user; if the dialog is cancelled it returns undefined.

The browserWindow argument allows the dialog to attach itself to a parent window, making it modal.

The filters specifies an array of file types that can be displayed or selected when you want to limit the user to a specific type. For example:

{
  filters: [
    { name: 'Images', extensions: ['jpg', 'png', 'gif'] },
    { name: 'Movies', extensions: ['mkv', 'avi', 'mp4'] },
    { name: 'Custom File Type', extensions: ['as'] },
    { name: 'All Files', extensions: ['*'] }
  ]
}

The extensions array should contain extensions without wildcards or dots (e.g. 'png' is good but '.png' and '*.png' are bad). To show all files, use the '*' wildcard (no other wildcard is supported).

Note: On Windows and Linux an open dialog can not be both a file selector and a directory selector, so if you set properties to ['openFile', 'openDirectory'] on these platforms, a directory selector will be shown.

dialog.showOpenDialogSync(mainWindow, {
  properties: ['openFile', 'openDirectory']
})

dialog.showOpenDialog([browserWindow, ]options)

    • message String (可选) macOS -显示在输入框上方的消息。
    • securityScopedBookmarks Boolean (可选) masOS mas - 在打包提交到Mac App Store时创建 security scoped bookmarks
  • callback Function (可选)

Returns Promise<Object> - Resolve wih an object containing the following:

  • canceled - Boolean - whether or not the dialog was canceled.
  • filePaths String - An array of file paths chosen by the user. If the dialog is cancelled this will be an empty array.
  • bookmarks String macOS mas - An array matching the filePaths array of base64 encoded strings which contains security scoped bookmark data. securityScopedBookmarks 必须启用才能捕获数据。

dialog.showErrorBox(title, content)

  • title String - 显示在错误框中的标题.
  • content String - 显示在错误框中的文本内容.

显示一个显示错误消息的模态对话框。

这个API可以在 app 模块触发 ready 事件之前被安全地调用，它通常用在启动时报告错误。 在 Linux 上, ready 事件之前调用这个API, 消息将被发送到stderr, 并且不会出现GUI对话框。

dialog.showErrorBox(title, content)

  • title String - The title to display in the error box.
  • content String - The text content to display in the error box.

Displays a modal dialog that shows an error message.

This API can be called safely before the ready event the app module emits, it is usually used to report errors in early stage of startup. If called before the app readyevent on Linux, the message will be emitted to stderr, and no GUI dialog will appear.

dialog.showCertificateTrustDialog([browserWindow, ]options, callback) macOS Windows

  • browserWindow BrowserWindow (可选)

  • options Object

    • certificate Certificate - 信任/导入的证书
    • message String - 要向用户显示的消息
  • callback Function

在macOS中, 将弹出一个用于展示消息与证书信息并向用户提供信任/导入证书的选项的模态对话框。 如果提供 browserWindow 参数, 则该对话框将附加到父窗口, 使其成模态框。

在Windows中, 受限于Win32 API，可选项变得更为有限:

  • message 参数无效，因为操作系统提供了自身的确认对话框。
  • browserWindow 参数被忽略，因此无法成为模态对话框。

即将弃用

dialog.showCertificateTrustDialog([browserWindow, ]options, callback) macOS Windows

  • browserWindow BrowserWindow (optional)

  • options Object

    • certificate Certificate - The certificate to trust/import.
    • message String - The message to display to the user.
  • callback Function

On macOS, this displays a modal dialog that shows a message and certificate information, and gives the user the option of trusting/importing the certificate. If you provide a browserWindow argument the dialog will be attached to the parent window, making it modal.

On Windows the options are more limited, due to the Win32 APIs used:

  • The message argument is not used, as the OS provides its own confirmation dialog.
  • The browserWindow argument is ignored since it is not possible to make this confirmation dialog modal.

Deprecated Soon

On macOS, this displays a modal dialog that shows a message and certificate information, and gives the user the option of trusting/importing the certificate. If you provide a browserWindow argument the dialog will be attached to the parent window, making it modal.

On Windows the options are more limited, due to the Win32 APIs used:

  • The message argument is not used, as the OS provides its own confirmation dialog.
  • The browserWindow argument is ignored since it is not possible to make this confirmation dialog modal.

工作表

在MaCOS中，如果在<0>browserWindow</0>的参数中提供<0>BrowerWindow</0>这一参数，或者在非<0>browserWindow</0>中未提供<0>modals</0>参数，则将对附加到<0>window</0>中的<0>sheet</0>的形式呈现。

您可以调用 BrowserWindow.getCurrentWindow().setSheetOffset(offset) 来更改附加工作表的窗口框架的偏移量。

Sheets

On macOS, dialogs are presented as sheets attached to a window if you provide a BrowserWindow reference in the browserWindow parameter, or modals if no window is provided.

You can call BrowserWindow.getCurrentWindow().setSheetOffset(offset) to change the offset from the window frame where sheets are attached.
