微信小程序页面结构和组件练习--音乐播放器
说明:
- 这个项目旨在练习组件以及页面的设计。页面和交互的实现可能有多种方式,这里只为了对组件和项目的结构进行熟悉了解。后续会有更加完善的项目。
- 由于涉及到mp3外链导入音乐,预览二维码在外链失效时会出错,这里不放预览二维码了;另预览二维码存在有效时长,有兴趣的可以自己试着运行程序,在运行程序之前更换mp3外链的地址,以防出错。mp3外链获取(音乐外链在线获取_音乐外链生成网站_音乐在线听-mp3外链网 (xf1433.com))。
- 喜欢的可以点个赞,如果有问题或者想要完整的项目代码及素材,评论区有百度云链接。
效果图:
- 三个页面通过轮播图的方式进行切换并实现一定的交互效果。其中,音乐推荐页没有设定交互;播放器页的进度条具有滑动可改变进度;播放列表页具有播放列表音乐的事件;底部的显示区域具有控制音频的交互。
- 遇到的问题:布局嵌套;初始数据的访问;渲染的嵌套使用;
bug:
- 播放器页面的播放时长和进度条的显示:页面首次加载获取不到默认曲目的音频时长。按下一首和播放列表进行播放也不显示,按暂停后再按播放就能正常显示。
代码部分:
- 这里给出项目的代码,没给出代码却存在的文件内容为空。关于素材方面,icon和img分别是图片和图标文件夹;照片是平时拍的,图标在阿里巴巴图标库找的(iconfont-阿里巴巴矢量图标库)。
