How to use the Layui framework to develop a video player that supports online preview of videos
Introduction:
With the rapid development of the Internet, videos have become people's daily life and an integral part of the job. Nowadays, thousands of video files exist on the Internet, and users hope to preview and play videos online quickly and easily. This article will introduce how to use the Layui framework to develop a video player that supports online preview of videos, and provide specific code examples.
1. Introduction to Layui Framework
Layui is a lightweight front-end framework developed by the Xianxin team. It is characterized by simplicity, ease of use and expansion. It provides a variety of commonly used components and tools, which are very suitable for quickly building web interfaces.
2. Preparation
3. Basic construction of video player
<div id="videoContainer"></div>
<div id="controlBar"> <button class="layui-btn layui-btn-primary layui-icon layui-icon-play" id="playButton"></button> <button class="layui-btn layui-btn-primary layui-icon layui-icon-pause" id="pauseButton"></button> <input type="range" id="progressBar" min="0" max="100" value="0" step="1" /> <span id="currentTime">00:00</span>/<span id="duration">00:00</span> </div>
4. Logic implementation of video player
layui.define(['jquery'], function(exports) { var $ = layui.jquery; var VideoPlayer = function(options) { this.options = $.extend({}, options); this.init(); }; VideoPlayer.prototype = { init: function() { this.video = document.createElement('video'); this.video.src = this.options.src; $('#videoContainer').append(this.video); this.playButton = $('#playButton'); this.pauseButton = $('#pauseButton'); this.progressBar = $('#progressBar'); this.currentTime = $('#currentTime'); this.duration = $('#duration'); this.bindEvents(); }, bindEvents: function() { var _this = this; this.playButton.on('click', function() { _this.play(); }); this.pauseButton.on('click', function() { _this.pause(); }); this.progressBar.on('change', function() { _this.seek(); }); this.video.addEventListener('timeupdate', function() { _this.updateProgress(); }); }, play: function() { this.video.play(); }, pause: function() { this.video.pause(); }, seek: function() { var progress = this.progressBar.val(); var duration = this.video.duration; var time = (progress / 100) * duration; this.video.currentTime = time; }, updateProgress: function() { var currentTime = this.video.currentTime; var duration = this.video.duration; var progress = (currentTime / duration) * 100; this.progressBar.val(progress); this.currentTime.text(this.formatTime(currentTime)); this.duration.text(this.formatTime(duration)); }, formatTime: function(time) { var minutes = Math.floor(time / 60); var seconds = Math.floor(time % 60); return (minutes < 10 ? '0' : '') + minutes + ':' + (seconds < 10 ? '0' : '') + seconds; } }; exports('VideoPlayer', VideoPlayer); });
<script src="layui.js"></script> <script> layui.use(['jquery', 'VideoPlayer'], function() { var $ = layui.jquery; var VideoPlayer = layui.VideoPlayer; var videoPlayer = new VideoPlayer({ src: 'video.mp4' }); }); </script>
