javascript - 加载文档时的全屏浏览器窗口

Question

如何在加载页面后全屏显示浏览器窗口？ 我在 jQuery 中使用了如下代码，但它仅使用事件 click; 但我希望它在加载时起作用。

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();
            }

    }
});

..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，则不可能强制全屏显示
