How to select a file programmatically?

Question

JavaScript

Hello!
How can I specify a file from the local file system in the "file"() type field in the extension.
Ideally, of course, specify the URL in the file field. Just select a file, no form required !
Googled all day, there are NO working solutions ... Tell me where to dig, who knows ....

Answer 1

In general, who cares... There is a great solution, in the debugger, the DOM.setFileInputFiles method.
True, it only supports local files, you can't add blobs... but that's not a problem!
