This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

FileSystemDirectoryEntry 接口方法 removeRecursively () removes the directory as well as all of its content, hierarchically iterating over its entire subtree of descendant files and directories.

To remove a single file, or an empty directory, you can also use FileSystemEntry.remove() .

句法

FileSystemDirectoryEntry.removeRecursively(successCallback[, errorCallback]);

参数

successCallback
errorCallback 可选: A function to be called if an error occurs while attempting to remove the directory subtree. Receives a FileError describing the error which occurred as input.

返回值

undefined .

错误

If an error occurs and an errorCallback was specified, it gets called with a single parameter: a FileError object describing the error. The FileError.code specifies what type of error occurred, as follows:

FileError.INVALID_MODIFICATION_ERR

An attempt was made to remove the root directory; this is not permitted.

FileError.NO_MODIFICATION_ALLOWED_ERR

The file system's state doesn't permit modification.

FileError.NOT_FOUND_ERR

The directory represented by the


									FileSystemDirectoryEntry

no longer exists.

FileError.NOT_READABLE_ERR

The directory is not accessible; perhaps it's in use by another application or is locked at the operating system level.

FileError.SECURITY_ERR

The directory could not be removed for security reasons. Possible reasons include:

The directory and/or its contents may not be safe to access from a Web application.
Too many file system calls are being made.
Other security concerns as raised by the user agent or the operating system.

If you try to delete a directory which contains one or more files that can't be removed, or if an error occurs while deletion of a number of files is underway, some files may not be deleted. You should provide an errorCallback to watch for and handle this, perhaps by trying again.

范例

directory.removeRecursively(function() {
  /* The directory was removed successfully */
}, function() {
  /* an error occurred while removing the directory */
});
