=head1 DESCRIPTION |
53
|
|
|
|
|
|
|
|
54
|
|
|
|
|
|
|
An object of this type is returned by the L<HTML::Object::DOM::Element::Input/files> property of the HTML C<<input>> element; this lets you access a list of files you would have set or added, removed, etc.. It inherits from L<Module::Generic::Array> |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
Normally, under JavaScript, those files are selected with the C<<input type="file" />> element. It is also used on the web for a list of files dropped into web content when using the drag and drop API; see the L<DataTransfer object on Mozilla|https://developer.mozilla.org/en-US/docs/Web/API/DataTransfer> for details on this usage. |
