先上一张效果图：

以前用angularjs操作基本上都是要取到每个列表的id再循环判断是不是当前点击的列表来显示折叠。

今天在这个项目 https://github.com/IFmiss/vue-music 上看到操作很简单，并没有如此复杂。赶紧记录一下：

折叠列表单独做一个组件，图标是用的iconfont中生成的css链接：myMusicSheetList.vue

<template> <div class="sheet-list"> <div class="sheet-header" @click="toggleSheet"> <i class="icon iconfont icon-enter" ref="toggleicon"></i> <span class="sheet-header-span">{{data_item.name}} <span> ({{data_item.num}}) </span></span> <i class="sheet-header-i icon iconfont icon-setup" @click.stop="showSheetMenu(data_item.name)"></i> </div> <div v-if="showSheets" class="sheet-content" v-for="i in data_item.details"> <div class="sheet-content-image"> <img :src="i.details_image" width="50" height="50" style="padding: 5px;overflow: hidden"> </div> <div class="sheet-content-middle"> <p style="">{{i.details_name}}</p> <p style="margin-top: 10px;font-size: 14px;color: #666">{{i.details_num}}首歌曲</p> </div> <i class="icon iconfont icon-switch" @click.stop="showSheetMenu()"></i> </div> </div></template><script>export default { components:{}, props: { item:{ type:Object } }, data(){ return{ showSheets:false, data_item:{} } }, methods:{//向右的小图标动画 toggleSheet:function(index){ console.log(this.$refs); this.$refs.toggleicon.style.transform = !this.showSheets ? 'rotate(90deg)' : 'rotate(0)'this.showSheets = !this.showSheets }, showSheetMenu:function(){ alert(1111); } }, created(){ this.data_item = this.item; },}</script><style scoped>.sheet-list{clear: both;}.sheet-header{height: 30px;background: #e5e5e5;position: relative;}.sheet-header i:nth-child(1){line-height: 30px;position:absolute;left:10px;color:#666;transition:all 0.5s;}.sheet-header-i{line-height: 30px;position: absolute;right: 10px;}.sheet-header-span{left: 40px;font-size: 14px;position:absolute;line-height: 30px;}.sheet-content{position: relative;width: 100%;display: flex;}.sheet-content i{font-size: 26px;position: absolute;right: 10px;top: 50%;transform:translate(0,-50%);}.sheet-content-image{width: 60px;float: left;text-align: center;}.sheet-content-middle{position: relative;width: 100%;border-bottom: 1px solid #e5e5e5;padding-bottom: 10px;margin-top: 10px;margin-left: 10px;}.sheet-content-middle p{font-size: 16px;width: 70%;color: #666;text-overflow:ellipsis;white-space: nowrap;overflow:hidden;}</style>

主页面调用组件：home.vue

<template> <div class="home"><sheet-list v-for="(item,index) in sheetList" :item="item"></sheet-list> </div></template><script>import myMusicSheetList from './../../components/myMusicSheetList.vue'export default { components:{'sheet-list':myMusicSheetList}, data () { return { sheetList:[{ id:1, name:'我创建的歌单', num:2, details:[{ details_id:1, details_name:'我喜欢的音乐', details_num:30, details_image:'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1521191038714&di=117b8f1d83605767e8a7faf01cb9be9b&imgtype=0&src=http%3A%2F%2Fimgsrc.baidu.com%2Fimgad%2Fpic%2Fitem%2F8435e5dde71190efc4376916c41b9d16fcfa602f.jpg' },{ details_id:2, details_name:'在欧洲田园般的乡村上骑单车', details_num:15, details_image:'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1521190642670&di=67822ec270160c1fb21e67d49e95a97f&imgtype=0&src=http%3A%2F%2Fpic30.nipic.com%2F20130615%2F2861027_140302450156_2.jpg' }] },{ id:2, name:'我收藏的歌单', num:2, details:[{ details_id:1, details_name:'这应该是你比较喜欢听的歌曲了', details_num:10, details_image:'https://ss1.bdstatic.com/70cFvXSh_Q1YnxGkpoWK1HF6hhy/it/u=3679981803,1758706610&fm=27&gp=0.jpg' },{ details_id:2, details_name:'欧美风格的音乐，安静的听', details_num:2, details_image:'https://ss0.bdstatic.com/70cFuHSh_Q1YnxGkpoWK1HF6hhy/it/u=2406805917,4090912031&fm=27&gp=0.jpg' }] }] } }, methods: { }, mounted:function(){ }}</script><style scoped></style>

如果不能运行请检查import 路径是否正确。
