FileSystemDirectoryReader - Web API 接口参考 编辑

非标准
该特性是非标准的，请尽量不要在生产环境中使用它！

The FileSystemDirectoryReader interface of the File and Directory Entries API lets you access the FileEntry-based objects (generally FileSystemFileEntry or FileSystemDirectoryEntry) representing each entry in a directory.

Because this is a non-standard API, whose specification is not currently on a standards track, it's important to keep in mind that not all browsers implement it, and those that do may implement only small portions of it. Check the Browser compatibility section for details.

Methods

readEntries()

Returns a an array containing some number of the directory's entries. Each item in the array is an object based on FileSystemEntry—typically either FileSystemFileEntry or FileSystemDirectoryEntry.
