前言

html浏览器全屏操作，基于jquery
iframe全屏、指定标签全屏

实现

css

/** 全屏*/
.lay-dbclick-box{position: relative;width: 100%;height: 100%;
}
.lay-dbclick-screen{position: absolute;top: 0;left: 0;width: 100%;height: 100%;z-index: 99999999999999;
}
.lay-fullScreen{position: fixed;left: 0;top: 0;border-radius: 0;padding: 0;margin: 0;width: 100%;height: 100%;z-index: 9999999999999;
}

html
关键是lay-dbclick-box和lay-dbclick-screen，其中的iframe是内容

<div class="lay-dbclick-box"><iframe src="" width="100%" height="100%" id="fullb" frameborder="0" allowfullscreen="" ></iframe><div class="lay-dbclick-screen"></div>
</div>

js

openFullScreen();/*** -------------------------------------------------------------------------------------------------------* 通用全屏操作*/
function openFullScreen(){// 双击全屏/退出全屏$(".lay-dbclick-screen").dblclick(function(){var val = $(this).parent().attr("lay-svalue");if(!val){$(this).parent().addClass("lay-fullScreen");$(this).parent().attr("lay-svalue", 1);fullScreen();}else{$(this).parent().removeClass("lay-fullScreen");$(this).parent().attr("lay-svalue", "");exitFullscreen();}})// 全屏事件监听document.addEventListener("fullscreenchange", function(){if (getFullscreenElement() == null) {console.log("-----------------[退出全屏]--------------")$(".lay-fullScreen").attr("lay-svalue", "");$(".lay-fullScreen").removeClass("lay-fullScreen");exitFullscreen();}else {console.log("-----------------[打开全屏]--------------")}})
}/*** -------------------------------------------------------------------------------------------------------* 获取全屏状态*/
function getFullscreenElement(){return (document['fullscreenElement'] ||document['mozFullScreenElement'] ||document['msFullScreenElement'] ||document['webkitFullscreenElement'] || null);
}/*** -------------------------------------------------------------------------------------------------------* 全屏*/
function fullScreen() {var element = document.documentElement;if (element.requestFullscreen) {element.requestFullscreen();} else if (element.msRequestFullscreen) {element.msRequestFullscreen();} else if (element.mozRequestFullScreen) {element.mozRequestFullScreen();} else if (element.webkitRequestFullscreen) {element.webkitRequestFullscreen();}
}/*** --------------------------------------------------------------------------------------------------------* 退出全屏*/
function exitFullscreen() {if (document.exitFullscreen) {document.exitFullscreen();} else if (document.msExitFullscreen) {document.msExitFullscreen();} else if (document.mozCancelFullScreen) {document.mozCancelFullScreen();} else if (document.webkitExitFullscreen) {document.webkitExitFullscreen();}
}
