微信小程序实现列表的横向滑动方式

2020年07月15日 作者：12程序猿原文

微信小程序原生方式实现列表的横向滑动的两种方法：

效果图：

overflow-x: auto;子元素设置：
display:inline-block;

方式二：scroll-view 标签 + 样式

scroll-view的横向滚动：

  • scroll-view的内层view元素需要：display：inline-block;
  • scroll-view的外层元素需要：white-space:nowrap;

实现代码：

1.wxml

<!--pages/packageA//multiple-function/multiple-function.wxml-->
<view class="content">
   <view class="Btn">
     <view class="clickBtn" data-id="" bindtap = "toClickTab">返回功能列表页</view>
   </view>
   <view>实现横向滚动效果：</view>
   <view style="margin-top: 60rpx;">
     方式一：<view>父元素设置 white-space:nowrap;//不换行 overflow-x: auto;</view>
        <view>子元素设置display:inline-block;</view>
   </view>
   <view class="listContent">
     <view class="item" wx:for="{{userList}}" wx:key="{{index}}">
       <image class="userAvatar" src="{{item.avatar}}" mode="aspectFit"/>
       <view class="userName">{{item.userName}}</view> 
     </view>
   </view> 
   <view style="margin-top: 60rpx;margin-bottom: 20rpx;">
    <view>方式二：scroll-view的横向滚动：</view>
    <view>scroll-view的内层view元素需要：display：inline-block;</view>
    <view>scroll-view的外层元素需要：white-space:nowrap;</view>
  </view>
  <view style="white-space:nowrap">
    <scroll-view scroll-x>
      <view class="listContent2">
        <view style="display: inline-block;" class="item2" wx:for="{{userList}}" wx:key="{{index}}">
          <image class="userAvatar" src="{{item.avatar}}" mode="aspectFit"/>
          <view class="userName">{{item.userName}}</view> 
        </view>
      </view> 
    </scroll-view>
  </view>
</view>

2.js

// pages/packageA//multiple-function/multiple-function.js
Page({

 /**
  * 页面的初始数据
  */
 data: {
  userList:[
   {'id':"1","avatar":"../../../images/tarbar/my-selected.png","userName":"用户1"},
   {'id':"2","avatar":"../../../images/tarbar/my-selected.png","userName":"用户2"},
   {'id':"3","avatar":"../../../images/tarbar/my-selected.png","userName":"用户3"},
   {'id':"4","avatar":"../../../images/tarbar/my-selected.png","userName":"用户4"},
   {'id':"5","avatar":"../../../images/tarbar/my-selected.png","userName":"用户5"},
   {'id':"6","avatar":"../../../images/tarbar/my-selected.png","userName":"用户6"},
   {'id':"7","avatar":"../../../images/tarbar/my-selected.png","userName":"用户7"},
   {'id':"8","avatar":"../../../images/tarbar/my-selected.png","userName":"用户8"},
   {'id':"9","avatar":"../../../images/tarbar/my-selected.png","userName":"用户9"},
   {'id':"10","avatar":"../../../images/tarbar/my-selected.png","userName":"用户10"},
   {'id':"11","avatar":"../../../images/tarbar/my-selected.png","userName":"用户11"},
  ]
 },

 /**
  * 生命周期函数--监听页面加载
  */
 onLoad: function (options) {

 },

 /**
  * 生命周期函数--监听页面显示
  */
 onShow: function () {

 }
})
