I don't believe you can have the file picker come up by dispatching a click at the control. Plain javascript doesn't make it work; let alone using web assembly.

But the demo works perfectly on Firefox quantum and Microsoft edge... Le vendredi 4 mai 2018, dtapu… via monorail < monorail+v2.2182922724@chromium.org> a écrit :

I confirmed the demo didn't work with Safari and Firefox nightly. .click() opens a file chooser only if it is called in user gesture event handler. e.g. 'click' event handler. |
