我设法在一个按钮中设置了两个选项:点击时,视频开始播放并同时进入全屏。
这是html:
<video id="video1" class="video-small">
<source src="video/Marinela+Pinguinos-HD.mp4" type="video/mp4" class="video-file">
<source src="video/Marinela_Pinguinos-HD.webm" type="video/webm" class="video-file">
</video>
<button id="play" class="full-play-button" onclick="vidplay(); goFullscreen('video1')">Play fullscreen</button>
JAVASCRIPT:
function vidplay() {
var video = document.getElementById("video1");
var button = document.getElementsByClassName("full-play-button");
if (video.paused) {
video.play();
button.textContent = "||";
} else {
video.pause();
button.textContent = ">";
}
}
function goFullscreen(id) {
// Get the element that we want to take into fullscreen mode
var element = document.getElementById(id);
// These function will not exist in the browsers that don't support fullscreen mode yet,
// so we'll have to check to see if they're available before calling them.
if (element.mozRequestFullScreen) {
// This is how to go into fullscren mode in Firefox
// Note the "moz" prefix, which is short for Mozilla.
element.mozRequestFullScreen();
} else if (element.webkitRequestFullScreen) {
// This is how to go into fullscreen mode in Chrome and Safari
// Both of those browsers are based on the Webkit project, hence the same prefix.
element.webkitRequestFullScreen();
}
}
到目前为止事情进展顺利。进入全屏时,底部有一个类似默认播放器的东西,一个按钮可以退出全屏。
我想要实现的是能够在点击该按钮时暂停视频,但我不知道如何。
我能想到的是某种功能可以检测我们是否全屏,如果我们不是,它会暂停/停止(不确定我还不喜欢)视频。
这就是我想到的,但我真的是JS的新手而且它不起作用:
function exitPause() {
var video = document.getElementById("video1");
if (document.exitFullscreen) {
video.pause();
}
else if (document.mozCancelFullScreen) {
video.pause();
}
else if (document.webkitExitFullscreen) {
video.pause();
}
else if (element.msExitFullscreen) {
video.pause();
}
}
我做错了什么?我怎样才能实现呢?

使用fullscreenchange
事件处理程序:
video.addEventListener(
'fullscreenchange',
function(event) {
if (!document.fullscreenElement) {
video.pause();
}
},
false
);
注意:关注供应商前缀。

感谢Igor Gilyazov,我设法走得更远了。这就是代码现在的样子:
function vidplay() {
var video = document.getElementById("video1");
var button = document.getElementsByClassName("full-play-button");
video.addEventListener(
'webkitfullscreenchange',
function(event) {
if (!document.fullscreenElement && video.paused) {
video.play();
}
else {
video.pause();
}
},
false
);
}
全屏:
function goFullscreen(id) {
// Get the element that we want to take into fullscreen mode
var element = document.getElementById(id);
// These function will not exist in the browsers that don't support fullscreen mode yet,
// so we'll have to check to see if they're available before calling them.
if (element.mozRequestFullScreen) {
// This is how to go into fullscren mode in Firefox
// Note the "moz" prefix, which is short for Mozilla.
element.mozRequestFullScreen();
} else if (element.webkitRequestFullScreen) {
// This is how to go into fullscreen mode in Chrome and Safari
// Both of those browsers are based on the Webkit project, hence the same prefix.
element.webkitRequestFullScreen();
}
// Hooray, now we're in fullscreen mode!
}
现在发生的事情是,当我第一次点击按钮时,它会全屏播放并播放视频。当回到小屏幕时,它会暂停。
这很棒。
不幸的是,它只是每隔一次发生一次(下次无论是全长还是小时都会暂停,然后再次正确,然后错误等等)。
我知道我很接近,但还没有完全正常工作,有任何修改的想法吗?
