我试图创建一个漂亮的背景视频,顶部有一些文本以及一个可用于暂停和取消暂停视频的按钮,视频工作正常并循环,但我无法暂停视频。

js(我从here得到了这个代码,虽然它说“//只有”如果“循环”被删除“我已经尝试删除”循环“并且它仍然没有暂停:
var vid = document.getElementById("bgvid");
var pauseButton = document.querySelector("#polina button");
function vidFade() {
vid.classList.add("stopfade");
}
vid.addEventListener('ended', function()
{
// only functional if "loop" is removed
vid.pause();
// to capture IE10
vidFade();
});
pauseButton.addEventListener("click", function() {
vid.classList.toggle("stopfade");
if (vid.paused) {
vid.play();
pauseButton.innerHTML = "Pause";
} else {
vid.pause();
pauseButton.innerHTML = "Paused";
}
})

以下代码可让您暂停视频
$(function() {
$('#polina button').on("click", function() {
$('video')[0].pause();
});
});
编辑:将pause();
更改为play();
将完全符合您的预期。

您需要更具体地引用该按钮。
var playPause = document.querySelector("#playPause");
整个源playButton
的更改已更改为playPause
,这不是问题,只是偏好。间接选择器可能适用于document.querySelector()
,也可能不适用,因为它更容易接受简单的选择器(从经验来看,不确定是否记录在案。)
var vid = document.getElementById("bgvid");
var playPause = document.querySelector("#playPause");
function vidFade() {
vid.classList.add("stopfade");
}
vid.addEventListener('ended', function() {
// only functional if "loop" is removed
vid.pause();
// to capture IE10
vidFade();
});
playPause.addEventListener("click", function() {
if (vid.paused) {
vid.play();
playPause.innerHTML = "Pause";
} else {
vid.pause();
playPause.innerHTML = "Paused";
}
})
