将视频带到特定时间的 html5 视频按钮 [英] html5 video button that takes video to specific time

问题描述

我正在尝试放置一个无需控件即可自动播放的视频，但我想在视频下方添加三个自定义按钮，每个按钮将视频跳转到特定时间.不使用 Youtube、Vimeo 或任何其他托管视频.我已经能够链接到特定时间，但这会打开一个新窗口并且与跨浏览器不兼容.这可能吗?

I'm trying to place a video that autoplays without controls but I want to add three custom buttons below the video, each button jumps the video to a specific time. Not using Youtube, Vimeo or any other hosted video. I've been able to link to a specific time, but that opens a new window and isn't cross browser compatible. Is this possible?

<video id="movie" style="border:none;" width="575" height="240" preload autoplay controls>
<source src="video.ogv" type="video/ogg; codecs=theora,vorbis" />
<source src="video.mp4" type="video/mp4; codecs=avc1.42E01E,mp4a.40.2" />
<source src="video.webm" type="video/webm; codecs=vp8,vorbis" />
</video>

<p class="navBtns">
<a href="video.ogv#t=9" target="_blank"><img src="dot.png" /></a>
<a href="video.ogv#t=17" target="_blank"><img src="dot.png" /></a>
<a href="video.ogv#t=29" target="_blank"><img src="dot.png" /></a>
</p>

<script>
var v = document.getElementsByTagName('video')[0];
v.removeAttribute('controls') // '' in Chrome, "true" in FF9 (string)
v.controls // true
</script>

推荐答案

您的链接有两个不同的问题:

Your links feature two different problems:

1. 它们具有 target="_blank" 属性，因此它们会打开一个新窗口/选项卡.(摆脱那些)
2. 您要链接到视频本身，而不是链接到嵌入视频的页面.这不会按预期工作.

要在不离开页面的情况下直接控制页面上的视频，您需要一些 javascript.在这里，您将找到一个如何工作的示例.

To control a video on a page directly without leaving the page, you'll need some javascript. Here you'll find an example how this will work.

JS Fiddle:视频 CurrentTime 示例

您需要一个函数来跳转到点击您的一个链接的特定时间，例如(例如):

You'll need a function to jump to the specific time on click of one of your links, that would be (for instance):

var firstlink = document.getElementByTagName('a')[0];
firstlink.addEventListener("click", function (event) {
    event.preventDefault();
    myvideo.currentTime = 7;
    myvideo.play();
}, false);
