<script src="{{ STATIC_URL }}mediaelementjs/jquery.js"></script>
<script src="{{ STATIC_URL }}mediaelementjs/mediaelement-and-player.min.js"></script>
<link rel="stylesheet" href="{{ STATIC_URL }}mediaelementjs/mediaelementplayer.min.css" />
<script>
$(document).ready(function(){$('video, audio').mediaelementplayer({
// if the <video width> is not specified, this is the default
defaultVideoWidth: 480,
// if the <video height> is not specified, this is the default
defaultVideoHeight: 270,
// if set, overrides <video width>
videoWidth: -1,
// if set, overrides <video height>
videoHeight: -1,
// width of audio player
audioWidth: 400,
// height of audio player
audioHeight: 30,
// initial volume when the player starts
startVolume: 0.8,
// useful for <audio> player loops
loop: false,
// enables Flash and Silverlight to resize to content size
enableAutosize: true,
// the order of controls you want on the control bar (and other plugins below)
features: ['playpause','progress','current','duration','tracks','volume','fullscreen'],
// Hide controls when playing and mouse is not over the video
alwaysShowControls: false,
// force iPad's native controls
iPadUseNativeControls: false,
// force iPhone's native controls
iPhoneUseNativeControls: false,
// force Android's native controls
AndroidUseNativeControls: false,
// forces the hour marker (##:00:00)
alwaysShowHours: false,
// show framecount in timecode (##:00:00:00)
showTimecodeFrameCount: false,
// used when showTimecodeFrameCount is set to true

<video id="demo" width="720" height="600" controls="controls" preload="auto">

说我想添加一个包含时间信息的链接(例如,从开头起10秒) ,当我点击它时,视频应该从头开始播放,而不是从10秒开始播放。在下面的成绩单中。时间00:00:10是可以单击的链接。谁能给我一些关于如何做到这一点的指示?
Say I want to add a link that contains the time information (e.g., 10 seconds from the beginning), and when I click on it, the video should plays starting not from the beginning, but from 10 seconds and onwards. In the following transcript. The time 00:00:10 is a link that can be clicked on. Could anyone give me some pointers on how to do this?

第158行:这是一句好话。 00:00:10
Line 158: That is a good word. 00:00:10

推荐答案
以前回答建议使用 currentTime()
,这是HTML5中的 get / set
方法,但只有在MEJS中获取
方法。您应该使用(MEJS') setCurrentTime()
,以设置
开始时间所以,有一个按钮,如
The previous answer suggested to use currentTime()
, which is a get/set
method in HTML5 but only a get
method in MEJS. You should rather use (MEJS') setCurrentTime()
, to set
the starting time so, having a button like
<button class="button" id="play">play : starts at 8 seconds</button>
...你可以使用这个jQuery代码:
... you could use this jQuery code :
var media; // we need this global variable
jQuery(document).ready(function ($) {
$("video").mediaelementplayer({
success: function (mediaElement, domObject) {
media = mediaElement; // make it available for other functions
}
});
$(".button").on("click", function () {
media.setCurrentTime(8); // set starting time
media.play();
});
}); // ready
...或者你可以有更多按钮(不同的 ID
s)设置更多操作,例如
... or you could have more buttons (with different ID
s) to set more actions like
$("#parentContainer").on("click", ".button", function (event) {
if (event.target.id == "play") {
media.setCurrentTime(8);
media.play();
}
if (event.target.id == "pause") {
media.pause();
}
});
注意:视频应为预装
用于设置
属性。
