详解微信小程序scroll-view横向滚动的实践踩坑及隐藏其滚动条的实现

 scroll-view {
   width: 100%;
   white-space: nowrap; // 不让它换行
  }

// html大概长这样
<scroll-view scroll-x="true">
 <div class="tab-item">
  <img class="content-icon"/>
  <div></div>
 </div>
 <div class="tab-item">
  <img class="content-icon"/>
  <div></div>
 </div>
 <div class="tab-item">
  <img class="content-icon"/>
  <div></div>
 </div>
</scroll-view>

// css相应就大概长这样
scroll-view {
  display: flex;
  flex-wrap: nowrap;
}
.tab-item {
  display: flex;
  justify-content: center;
  width: 25%;
  ...
}

// html
<div class="scroll-view-container">
 <scroll-view scroll-x="true" :scroll-into-view="toView">
  <div class="tab-container">
   <div class="tab-item">
    <img class="content-icon"/>
    <div></div>
   </div>
  </div>
 </scroll-view>
</div>

// css变成这样子
scroll-view {
 width: 100%;
 white-space: nowrap; // 不让它换行
}

.tab-container {
 display: inline-block;
 width: 25%;
}

.tab-item {
  display: flex;
  flex-direction: column;
  align-items: center;
  ...
}

/*隐藏滚动条*/

::-webkit-scrollbar{

  width: 0;
  
  height: 0;
  
  color: transparent;

}

/*隐藏滚动条*/

::-webkit-scrollbar{

  display: none;

}

// scss
.scroll-view-container { // 包裹scroll-view的容器
  height: $fakeScrollHeight;
  overflow: hidden; // 这个设置了就能截掉滚动条啦
  scroll-view {
   width: 100%;
   white-space: nowrap;
  }
 }

 .tab-container { // 我这里是用.tab-container来撑开scroll-view的高度，所以高度在它上面设置,加上padding，那么它就会比外层容器（.scroll-view-container）要高
  display: inline-block;
  width: 26%;
  height: $fakeScrollHeight;
  padding-bottom: $scrollBarHeight;
 }
