js之切换全屏和退出全屏实现
应用场景:
比如很多网页游戏全屏之类的,或者是网上看小说等。
核心代码:
//控制全屏 function enterfullscreen() { //进入全屏 $("#fullscreen").html("退出全屏"); var docElm = document.documentElement; //W3C if(docElm.requestFullscreen) { docElm.requestFullscreen(); } //FireFox else if(docElm.mozRequestFullScreen) { docElm.mozRequestFullScreen(); } //Chrome等 else if(docElm.webkitRequestFullScreen) { docElm.webkitRequestFullScreen(); } //IE11 else if(elem.msRequestFullscreen) { elem.msRequestFullscreen(); } } function exitfullscreen() { //退出全屏 $("#fullscreen").html("切换全屏"); if(document.exitFullscreen) { document.exitFullscreen(); } else if(document.mozCancelFullScreen) { document.mozCancelFullScreen(); } else if(document.webkitCancelFullScreen) { document.webkitCancelFullScreen(); } else if(document.msExitFullscreen) { document.msExitFullscreen(); } } var a = 0; $('#fullscreen').on('click', function() { a++; a % 2 == 1 ? enterfullscreen() : exitfullscreen(); })
前端代码:
<a type="button" id="fullscreen" class="btn btn-default visible-lg visible-md"><i class="fa fa-refresh" aria-hidden="true"></i> 切换全屏</a>
