Resource preloading component——preload
Install:
git clone https://github.com/jayZOU/preload.git npm install npm run es6
Visit http://localhost:8080/es6-demo
Examples <audio pSrc="../public/audio/a.mp3" preload="auto" controls></audio> <audio pSrc="../public/audio/b.mp3" preload="auto" controls></audio> <img pSrc="../public/image/b1.jpg" alt=""> <img pSrc="../public/image/b2.jpg" alt=""> <img pSrc="../public/image/b3.jpg" alt=""> <img pSrc="../public/image/b4.jpg" alt=""> /** * Preload 资源预加载组件 * @author jayzou * @time 2016-1-12 * @version 1.0.6 * @class Preload * @param {object} sources 必填 加载队列容器,支持队列加载以及加载一个队列后传入回调 * @param {boolean} isDebug 选填 是否开启debug选项,用于移动端调试,默认false * @param {object} connector 选填 后台数据接口,可选择同步或异步 * @param int loadingOverTime 选填 预加载超时时间,默认15, 单位:秒 * @param {object} loadingOverTimeCB 选填 预加载超时回调 * @param {object} wrap 选填 进度条容器,返回记载进度信息 * @param {object} completeLoad 选填 完成所有加载项执行回调,包括同、异步获取数据 **/ var preload = new Preload({ isDebug: true, sources: { imgs: { source: [ "../public/image/b2.jpg", "../public/image/b1.jpg" ], callback: function() { console.log("队列1完成"); } }, audio: { source: [ "../public/audio/a.mp3", "../public/audio/b.mp3" ] }, imgs2: { source: [ "../public/image/b3.jpg", "../public/image/b4.jpg", "http://7xl041.com1.z0.glb.clouddn.com/OrthographicCamera.png", "http://7xl041.com1.z0.glb.clouddn.com/audio.gif", ], callback: function() { console.log("队列3完成"); } } }, loadingOverTime: 3, loadingOverTimeCB: function(res) { console.log("资源加载超时:", res); }, connector: { int1: { url: 'http://localhost/test/index.php?callback=read&city=上海市', jsonp: true }, int2: { url: 'http://localhost/test/index.php?callback=read&city=深圳市', jsonp: false, callback: function(data) { console.log("同步:", data); } } }, progress: function(completedCount, total) { // console.log(total); console.log(Math.floor((completedCount / total) * 100)); }, completeLoad: function() { console.log("已完成所有加载项"); } }); function read() { console.log("异步:", arguments[0]) }
Notes
Queue names cannot have the same name, otherwise the subsequent queue will overwrite the previous one
Written in ES6 mode, synchronous loading between queues, and resources within the queue are loaded asynchronously
Sliding screen component——slide
Install:
git clone https://github.com/jayZOU/slide.git npm install gulp
Visit http://localhost:8080/

Notes
The sliding container can only pass in the ID value, not class
