废话不多说,相当实用,先记录。
Html代码:
<div class="container"> <div class="page-title">滑动组件</div> <ul> <li class="list-item " v-for="(item,index) in list " data-type="0"> <div class="list-box" @touchstart.capture="touchStart" @touchend.capture="touchEnd" @click="skip"> <img class="list-img" :src="item.imgUrl" alt=""> <div class="list-content"> <p class="title">{{item.title}}</p> <p class="tips">{{item.tips}}</p> <p class="time">{{item.time}}</p> </div> </div> <div class="delete" @click="deleteItem" :data-index="index">删除</div> </li> </ul> </div>
注意:这里的数据全是本地 mock 的~
Css样式代码:
.page-title{ text-align: center; font-size: 17px; padding: 10px 15px; position: relative; } .page-title:after{ content: " "; position: absolute; left: 0; bottom: 0; right: 0; height: 1px; border-bottom: 1px solid #ccc; color: #ccc; -webkit-transform-origin: 0 100%; transform-origin: 0 100%; -webkit-transform: scaleY(0.5); transform: scaleY(0.5); z-index: 2; } .list-item{ position: relative; height: 1.6rem; -webkit-transition: all 0.2s; transition: all 0.2s; } .list-item[data-type="0"]{ transform: translate3d(0,0,0); } .list-item[data-type="1"]{ transform: translate3d(-2rem,0,0); } .list-item:after{ content: " "; position: absolute; left: 0.2rem; bottom: 0; right: 0; height: 1px; border-bottom: 1px solid #ccc; color: #ccc; -webkit-transform-origin: 0 100%; transform-origin: 0 100%; -webkit-transform: scaleY(0.5); transform: scaleY(0.5); z-index: 2; } .list-box{ padding: 0.2rem; background: #fff; display: flex; align-items: center; -webkit-box-sizing: border-box; box-sizing: border-box; justify-content: flex-end; position: absolute; top: 0; right: 0; bottom: 0; left: 0; font-size: 0; } .list-item .list-img{ display: block; width: 1rem; height: 1rem; } .list-item .list-content{ padding: 0.1rem 0 0.1rem 0.2rem; position: relative; flex: 1; flex-direction: column; align-items: flex-start; justify-content: center; overflow: hidden; } .list-item .title{ display: block; color: #333; overflow: hidden; font-size: 15px; font-weight: bold; text-overflow: ellipsis; white-space: nowrap; } .list-item .tips{ display: block; overflow: hidden; font-size: 12px; color: #999; line-height: 20px; text-overflow: ellipsis; white-space: nowrap; } .list-item .time{ display: block; font-size: 12px; position: absolute; right: 0; top: 0.1rem; color: #666; } .list-item .delete{ width: 2rem; height: 1.6rem; background: #ff4949; font-size: 17px; color: #fff; text-align: center; line-height: 1.6rem; position: absolute; top:0; right: -2rem; }
这是核心的样式代码,还有部分样式重置代码放在了 App.vue 里,通过计算根节点 html 的字体大小的脚本放在了 index.html 中~
js代码:
export default{ name: 'index', data () { return { list : [ { title : 'Chrome更新了' , imgUrl : './static/images/Chrome.png' , tips : '不再支持Flash视频播放' , time : '上午 8:30' }, { title : '电影新资讯' , imgUrl : './static/images/Sina.png' , tips : '电影《红海行动》上映以来票房暴涨,很多国人表示对国产电影有了新的改观' , time : '上午 12:00' }, { title : '聚焦两会·共筑中国梦' , imgUrl : './static/images/video.png' , tips : '两会故事' , time : '下午 17:45' }, { title : '微信团队' , imgUrl : './static/images/Wechat.png' , tips : '您的帐号有异常登录,如非本人操作,请及时修改密码' , time : '昨天' } ], startX : 0 , endX : 0 , } }, methods : { //跳转 skip(){ if( this.checkSlide() ){ this.restSlide(); }else{ alert('You click the slide!') } }, //滑动开始 touchStart(e){ // 记录初始位置 this.startX = e.touches[0].clientX; }, //滑动结束 touchEnd(e){ // 当前滑动的父级元素 let parentElement = e.currentTarget.parentElement; // 记录结束位置 this.endX = e.changedTouches[0].clientX; // 左滑 if( parentElement.dataset.type == 0 && this.startX - this.endX > 30 ){ this.restSlide(); parentElement.dataset.type = 1; } // 右滑 if( parentElement.dataset.type == 1 && this.startX - this.endX < -30 ){ this.restSlide(); parentElement.dataset.type = 0; } this.startX = 0; this.endX = 0; }, //判断当前是否有滑块处于滑动状态 checkSlide(){ let listItems = document.querySelectorAll('.list-item'); for( let i = 0 ; i < listItems.length ; i++){ if( listItems[i].dataset.type == 1 ) { return true; } } return false; }, //复位滑动状态 restSlide(){ let listItems = document.querySelectorAll('.list-item'); // 复位 for( let i = 0 ; i < listItems.length ; i++){ listItems[i].dataset.type = 0; } }, //删除 deleteItem(e){ // 当前索引 let index = e.currentTarget.dataset.index; // 复位 this.restSlide(); // 删除 this.list.splice(index,1); } } }
综上,亲测可用,叽叽叽叽叽叽~
