本篇内容主要讲解“微信小程序如何实现卡片层叠滑动”,感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习“微信小程序如何实现卡片层叠滑动”吧!
实现效果:
左右滑动时,向相应方向移动一个卡片位置;
2.点击某一项时,将点击项位置移动到中间位置;
代码如下:
wxml:
<view class="teachers_banner"> <view class="container clearfix teachers_b"> <view class="slide" id="slide" bindtouchstart='moveStart' bindtouchend='moveItem'> <ul> <block wx:for="{{datas}}"> <li animation="{{item.animation}}" bindtap="choose" data-id="{{item.id}}" > <image src="{{item.iamge}}" alt="林奇涵" title=""></image> </li> </block> </ul> </view> </view></view>
css:
.teachers_banner{ width:100%; height:575px; background-size: cover; position: relative; overflow: hidden;}.teachers_b{ position:relative; margin-top:130px;}#slide { margin: 0 auto; width: 100%; height: 330px; position: relative; } image{ width: 200rpx; height: 200rpx; }#slide li { position: absolute; width:200rpx; display: -webkit-box; display: -webkit-flex; display: flex; align-items: flex-start; -webkit-box-align: flex-start; -webkit-align-items: flex-start; background:#fff; overflow:hidden; box-shadow: 0 0 20px #1d374d;}#slide li img { width: 100%; height: 100%;}.slide_left{ }.slide_right{ padding: 40px; -webkit-box-flex: 1; -webkit-flex: 1; flex: 1; min-width: 0;}.slide_right h4{font: 400 30px/18px "Microsoft Yahei";color:#222222;}.slide_right h4 span{ display:inline-block; margin-left:10px; font: 400 14px/36px "Microsoft Yahei";color:#555555;}.slide_right p{ padding:20px 0 30px; color:#555555; font: 400 14px/24px "Microsoft Yahei"; border-bottom: 1px solid #dbdbdb;}.slide_right dl{ padding-top:30px;}.slide_right dd{ float: left; width:33.3%; color:#777; font: 400 12px/24px "Microsoft Yahei";}.slide_right dd h4{color:#ff9000;margin-bottom:20px;}.arrow { }.arrow .prev,.arrow .next { position: absolute; width: 64px; top: 38%; z-index: 9; font: 700 96px 'simsun'; opacity: 0.3; color: #fff; cursor: pointer;}.arrow .prev { }.arrow .next { }.arrow .prev:hover,.arrow .next:hover { color: #00a0e9; opacity: .7;}
