How to change filelist file

Question

I have this input type "file" and I want to change its list of files . Example:

 <input type = "file" id = "fileinput" /> <script type = "text/javascript> document.getElementById("fileinput").files = [10]; </script> 

The problem is that the fileinput element files list is not set. How to do it?

Answer 1

For security reasons, browsers do not allow javascript to modify the files that will be downloaded: only the user can select files through the user interface. This is done to prevent the evil script from loading /etc/passwd , for example, without the knowledge of the user.

The only exception is that calling “reset” on the form will clear the file or list of files, but you can never add them programmatically.

Answer 2

You want to use the multiple attribute in the input element. Thus, in new browsers, the user will be able to select several files to download.
