这篇文章主要介绍了vue实现歌手列表字母排序，下拉滚动条侧栏排序实时更新,非常不错，具有一定的参考借鉴价值，需要的朋友可以参考下
今天写项目的时候遇到了歌手排序的问题，联想到了我们平时的手机通讯录侧栏字母排序，按照ABCDE这样的顺序对名字进行排序。
我们先来看看效果
那就用vue来实现一遍
首先新建一个vue页面，取名为helloworld.vue
在页面里写入内容
<div class="hello"> <div class="singer" id="singer"> <div class="singer-top-tag">{{singerTopTag | filterSingerTag}}</div><ul class="singer-ul"> <li class="singer-ul-li"> <div class="singer-tag">{{item.tag | filterSingerTag}}</div><ul> <li> <div>{{fitem.Fsinger_name}}</div></li></ul></li></ul></div><div class="sort"> <ul> <li> {{item == `hot` ? `热` : item}} </li></ul></div></div>
<!-- Add "scoped" attribute to limit CSS to this component only --> .hello { position: relative; background-color: #222; } .singer { position: relative; width: 100%; height: 100%; overflow: hidden; background: #222; } .singer-top-tag { position: fixed; top: 0px; left: 0; width: 100%; height: 30px; line-height: 30px; padding-left: 20px; font-size: 12px; color: hsla(0,0%,100%,.5); background: #333; } .singer-tag { width: 100%; height: 30px; margin-bottom: 20px; line-height: 30px; padding-left: 20px; font-size: 12px; color: hsla(0,0%,100%,.5); background: #333; } .singer-ul-li ul li { list-style-type: none; display: flex; justify-content: flex-start; align-items: center; padding: 0 0 20px 20px; color: rgba(255, 255, 255, .5); } .singer-ul-li ul li img { border-radius: 50%; widows: 50px; height: 50px; } .singer-ul-li ul li div { padding-left: 20px; } .sort { position: fixed; z-index: 30; right: 0; top: 50%; -webkit-transform: translateY(-50%); transform: translateY(-50%); width: 20px; padding: 20px 0; border-radius: 10px; text-align: center; background: rgba(0,0,0,.3); font-family: Helvetica; } ul { margin: 0; padding: 0; } .sort ul{ color: rgba(255,255,255,.6); } .sort ul li { list-style-type: none; padding: 3px; line-height: 1; font-size: 12px; } .current { color: #ffcd32; }
我是使用的qq音乐接口，获取的数据需要进行处理，如果觉得麻烦可以自己写静态数据来代替
数据的格式
const list = [ { tag:`A`, data:[ { img:`https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1558361071&di=0a522afe68fc7e2aa3af34cb5cd8c96a&imgtype=jpg&er=1&src=http%3A%2F%2Fwerkstette.dk%2Fwp-content%2Fuploads%2F2015%2F09%2FEntertainment_Weekly_Photographer_Marc_Hom_British_Actor_Charlie_Hunnam_as_King_Arthur_Retouch_Werkstette10-770x841.jpg-600`, Fsinger_name:`奥巴里` } ] }， { tag:`B`, data:[ { img:`https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1558361071&di=0a522afe68fc7e2aa3af34cb5cd8c96a&imgtype=jpg&er=1&src=http%3A%2F%2Fwerkstette.dk%2Fwp-content%2Fuploads%2F2015%2F09%2FEntertainment_Weekly_Photographer_Marc_Hom_British_Actor_Charlie_Hunnam_as_King_Arthur_Retouch_Werkstette10-770x841.jpg-600`, Fsinger_name:`BIGBANG` } ] }, { tag:`C`, data:[ { img:`https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1558361071&di=0a522afe68fc7e2aa3af34cb5cd8c96a&imgtype=jpg&er=1&src=http%3A%2F%2Fwerkstette.dk%2Fwp-content%2Fuploads%2F2015%2F09%2FEntertainment_Weekly_Photographer_Marc_Hom_British_Actor_Charlie_Hunnam_as_King_Arthur_Retouch_Werkstette10-770x841.jpg-600`, Fsinger_name:`蔡依林` } ] }, { tag:`D`, data:[ { img:`https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1558361071&di=0a522afe68fc7e2aa3af34cb5cd8c96a&imgtype=jpg&er=1&src=http%3A%2F%2Fwerkstette.dk%2Fwp-content%2Fuploads%2F2015%2F09%2FEntertainment_Weekly_Photographer_Marc_Hom_British_Actor_Charlie_Hunnam_as_King_Arthur_Retouch_Werkstette10-770x841.jpg-600`, Fsinger_name:`邓紫棋` } ] }, ]
再者还要注意页面的img标签，直接复制上面的数据的话要对img标签进行修改，去掉http那一串，直接用:src="item.img"代替
const list = [ { tag:`A`, data:[ { img:`https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1558361071&di=0a522afe68fc7e2aa3af34cb5cd8c96a<strong>本文来源gaodai#ma#com搞@@代~&码网</strong>&imgtype=jpg&er=1&src=http%3A%2F%2Fwerkstette.dk%2Fwp-content%2Fuploads%2F2015%2F09%2FEntertainment_Weekly_Photographer_Marc_Hom_British_Actor_Charlie_Hunnam_as_King_Arthur_Retouch_Werkstette10-770x841.jpg-600`, Fsinger_name:`奥巴里` } ] }， { tag:`B`, data:[ { img:`https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1558361071&di=0a522afe68fc7e2aa3af34cb5cd8c96a&imgtype=jpg&er=1&src=http%3A%2F%2Fwerkstette.dk%2Fwp-content%2Fuploads%2F2015%2F09%2FEntertainment_Weekly_Photographer_Marc_Hom_British_Actor_Charlie_Hunnam_as_King_Arthur_Retouch_Werkstette10-770x841.jpg-600`, Fsinger_name:`BIGBANG` } ] }, { tag:`C`, data:[ { img:`https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1558361071&di=0a522afe68fc7e2aa3af34cb5cd8c96a&imgtype=jpg&er=1&src=http%3A%2F%2Fwerkstette.dk%2Fwp-content%2Fuploads%2F2015%2F09%2FEntertainment_Weekly_Photographer_Marc_Hom_British_Actor_Charlie_Hunnam_as_King_Arthur_Retouch_Werkstette10-770x841.jpg-600`, Fsinger_name:`蔡依林` } ] }, { tag:`D`, data:[ { img:`https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1558361071&di=0a522afe68fc7e2aa3af34cb5cd8c96a&imgtype=jpg&er=1&src=http%3A%2F%2Fwerkstette.dk%2Fwp-content%2Fuploads%2F2015%2F09%2FEntertainment_Weekly_Photographer_Marc_Hom_British_Actor_Charlie_Hunnam_as_King_Arthur_Retouch_Werkstette10-770x841.jpg-600`, Fsinger_name:`邓紫棋` } ] }, ]
