加载文档时的全屏浏览器窗口 [英] full-screen browser window on load document

问题描述

如何在加载页面后全屏浏览器窗口?我在 jQuery 中使用过类似下面的代码，但它只能使用 click 事件；但我希望它可以用于负载.

How can I full-screen browser window after loading the page? I have used code like below in jQuery but its working only using the event click; but I want that to be worked on load.

jQuery(document).ready(function($) {
    function fullScreen(){
            var docElm = document.documentElement;
            if (docElm.requestFullscreen) {
                //alert("requestFullscreen");
                docElm.requestFullscreen();
            }
            else if (docElm.mozRequestFullScreen) {
                //alert("mozRequestFullScreen");
                docElm.mozRequestFullScreen();
            }
            else if (docElm.webkitRequestFullScreen) {
                //alert("webkitRequestFullScreen");
                docElm.webkitRequestFullScreen();
            }

    }
});

推荐答案

来自 https://wiki.mozilla.org/Gecko:FullScreenAPI#Suggested_UA_Policy

..requestFullScreen 当窗口已经处于全屏状态时被批准.否则，requestFullScreen 在用户操作之外(例如非合成输入事件处理程序)被拒绝.

..requestFullScreen while the window is already in the full-screen state is approved. Otherwise, requestFullScreen outside a user action (e.g. a non-synthesized input event handler) is denied.

因此，如果不是由用户操作触发，则不可能强制全屏

so it's not possible force a fullscreen if it's not triggered by a user action
