VueDemo3:音乐播放器
一.歌曲搜索
1。按下回车(v-on,enter)
2.查询数据(axios 接口 v-model)
3.渲染数据(v-for 数组 that)
服务器返回的数据比较复杂时,获取的时候需要注意层级结构
通过审查元素快速定位到需要操纵的元素
二.歌曲播放
根据服务器检索结果,找到歌曲播放的url。
通过v-bind,刷新标签中的src属性,以实现播放不同音乐的效果。
歌曲id依赖歌曲搜索的结果,对于不用的数据也需要关注。
三.播放动画
audio标签的play事件会在音频播放的时候触发
audio标签的pause事件会在音频暂停的时候触发
通过对象的方式设置类名,类名的生效与否取决于后面值的真假
四.MV播放
1.mv图标显示(v-if)
2.mv地址获取(接口 mvid)
3.遮罩层(v-show v-on)
4.mv地址设置(v-bind)
不同的接口需要的数据是不同的,文档的阅读需要仔细
页面结构复杂之后,通过审查元素的方式去快速定位相关元素
响应式的数据都需要定义在data中定义
自己写的么得css,巨丑。就放后来下载的老师的源码了。
那个跟B站听的课,老师课程链接也放一下吧:
https://www.bilibili.com/video/BV12J411m7MG?p=1 配套源码我上传一下试试,不知道会不会侵权,
侵权的话就删了回头,加这个黑马的QQ:2212232413
