full-screen browser window on load document
提问by itsazzad
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.
加载页面后如何全屏浏览器窗口？我在 jQuery 中使用过类似下面的代码，但它只能使用事件click；但我希望在负载上工作。
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.
..requestFullScreen 当窗口已经处于全屏状态时被批准。否则，拒绝用户操作（例如，非合成输入事件处理程序）之外的requestFullScreen 。
so it's not possible force a fullscreen if it's not triggered by a user action
因此，如果不是由用户操作触发，则不可能强制全屏显示
