requestFullscreen全屏具体实现
1.进入全屏
function full(ele) {
if (ele.requestFullscreen) {
ele.requestFullscreen();
} else if (ele.mozRequestFullScreen) {
ele.mozRequestFullScreen();
} else if (ele.webkitRequestFullscreen) {
ele.webkitRequestFullscreen();
} else if (ele.msRequestFullscreen) {
ele.msRequestFullscreen();
}
}
ele
:要全屏的元素,可以是document.body
也可以是某一个div
思路:
1.判断该浏览器是否具有requestFullscreen
方法
2.有,则直接执行ele.requestFullscreen()
;没有则做浏览器兼容判断。
2.exitFullScreen退出全屏
function exitFullscreen() {
if(document.exitFullScreen) {
document.exitFullScreen();
} else if(document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if(document.webkitExitFullscreen) {
document.webkitExitFullscreen();
} else if(document.msExitFullscreen) {
document.msExitFullscreen();
}
}
退出全屏直接使用document
调用exitFullscreen
方法即可。
3.获取当前全屏的节点
function getFullscreenElement() {
return (
document.fullscreenElement ||
document.mozFullScreenElement ||
document.msFullScreenElement ||
document.webkitFullscreenElement||null
);
}
document.fullscreenElement()
:获取当前全屏的元素。
假设id为div1的Element当前为全屏状态则 document.querySelector("#div1")===document.fullscreenElement
4.判断当前是否全屏
function isFullScreen() {
return !! (
document.fullscreen ||
document.mozFullScreen ||
document.webkitIsFullScreen ||
document.webkitFullScreen ||
document.msFullScreen
);
}
5.判断当前文档是否能切换到全屏
function isFullscreenEnabled() {
return (
document.fullscreenEnabled ||
document.mozFullScreenEnabled ||
document.webkitFullscreenEnabled ||
document.msFullscreenEnabled
);
}
注意事项:
1.document
下没有requestFullscreen
2.requestFullscreen
方法只能由用户触发,比如:在onload
事件中不能触发
3.页面跳转需先退出全屏
4.进入全屏的元素,将脱离其父元素,所以可能导致之前某些css的失效
解决方案:使用 :full-screen
伪类 为元素添加全屏时的样式(使用时为了兼容注意添加-webkit、-moz或-ms前缀)
5.一个元素A全屏后,其子元素要再全屏,需先让元素A退出全屏
单击播放/暂停。
function onDocumentClick(event) { clearTimeout(clickTimeId); //执行延时 clickTimeId = setTimeout(function() { //此处为单击事件要执行的代码 if(video.paused){ video.play(); }else{ video.pause(); } }, 250);}双击全屏/解除全屏function onDocumenDblClick(event) { clearTimeout(clickTimeId); console.log("鼠标双击"); console.log(isFullScreen()) if(isFullScreen()){ exitFullscreen() }else{ full(video) } } 隐藏vedio控件 css :
video::-webkit-media-controls{ display:none !important;}
