scroll-view——小程序横向滚动

Posted 2020-09-23 Anne3

这是官方给的布局代码

<view class="section">
  <view class="section__title">vertical scroll</view>
  <scroll-view scroll-y style="height: 200px;" bindscrolltoupper="upper" bindscrolltolower="lower" bindscroll="scroll" scroll-into-view="{{toView}}" scroll-top="{{scrollTop}}">
    <view id="green" class="scroll-view-item bc_green"></view>
    <view id="red"  class="scroll-view-item bc_red"></view>
    <view id="yellow" class="scroll-view-item bc_yellow"></view>
    <view id="blue" class="scroll-view-item bc_blue"></view>
  </scroll-view>

  <view class="btn-area">
    <button size="mini" bindtap="tap">click me to scroll into view </button>
    <button size="mini" bindtap="tapMove">click me to scroll</button>
  </view>
</view>
<view class="section section_gap">
  <view class="section__title">horizontal scroll</view>
  <scroll-view class="scroll-view_H" scroll-x style="width: 100%">
    <view id="green" class="scroll-view-item_H bc_green"></view>
    <view id="red"  class="scroll-view-item_H bc_red"></view>
    <view id="yellow" class="scroll-view-item_H bc_yellow"></view>
    <view id="blue" class="scroll-view-item_H bc_blue"></view>
  </scroll-view>
</view>

　　在文档上对css没有进行描述，要想横向滚动，首先要先把子元素设置成一行，发现float不能用

要对子元素进行display:inline-block ,容器进行 white-space: nowrap;

css如下：

.scroll-view_H{
  width: 100%;
  white-space: nowrap; 
}
.scroll-view-item_H{
  width: 200px;
  height: 100px;
  display: inline-block;
}
