javascript - how to initialize fullscreen without user interaction -

hi i'm beginner , want create web-app , needs in fullscreen when page load... without user interaction

i have @ click function works correctly... want load function @ start page

addeventlistener("click", function()      {         var el = document.documentelement , rfs = el.requestfullscreen ||         el.webkitrequestfullscreen || el.mozrequestfullscreen ;         rfs.call(el);     }); 

someone me :)

thank you!

that not possible.

i ran following snippet in browser console:

var e = document.getelementbyid('answers'); (e.webkitrequestfullscreen || e.mozrequestfullscreen).apply(e); 

chrome told me:

failed execute 'requestfullscreen' on 'element': api can initiated user gesture.

firefox told me:

request full-screen denied because element.mozrequestfullscreen() not called inside short running user-generated event handler.

that restriction put in place prevent abuse, similar on window.open (see this or this question example).
