Javascript Intercepted “Ctrl+O” Does Not Open My File Dialog

Question

I have an file-browser input in my HTML.

I have another button with ID choose-file-button

Answer 1

You cannot do that in all browsers, as far as I am concern only IE allow it. I guess this is due to security issues, so that programmer are disabled to set the file name on the HTML File element automatically(without permission of client).

have a look on this link for more details:
