How to implement the scroll view container of the WeChat applet

Directly upload the codes and renderings of the two solutions:

Option 1

This solution is to use the view directly and set the overflow: scroll

wxml:
 <view class="container">
  <view class="content" wx:for="{{11}}" wx:key="item">
    {{item}}
  </view>
</view>

Copy after login

wxss:

 .container {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: 100vh;
  overflow: scroll;
  padding-bottom: 20rpx;
  background: #FD9494;
}

.content {
  margin: 20rpx auto 0 auto;
  width: 710rpx;
  height: 300rpx;
  background: #ddd;
  border-radius: 16rpx;
  font-size: 80rpx;
  line-height: 300rpx;
  text-align: center;
}

Copy after login

Rendering:

##Option 2

Use scroll-view + container as the container

wxml:

<scroll-view class="main_container" scroll-y>
  <view class="container">
    <view class="content" wx:for="{{11}}" wx:key="item">
      {{item}}
    </view>
  </view>
</scroll-view>

Copy after login

wxss:

.main_container {
  position: relative;
  width: 750rpx;
  height: 100vh;
  background: #FD9494;
}

 .container {
  position: absolute; /*使用absolute的原因是因为为了防止第一个子视图有margin-top时，造成顶部留白的情况*/
  left: 0;
  top: 0;
  width: 100%;
  padding-bottom: 20rpx;
} 

.content {
  margin: 20rpx auto 0 auto;
  width: 710rpx;
  height: 300rpx;
  background: #ddd;
  border-radius: 16rpx;
  font-size: 80rpx;
  line-height: 300rpx;
  text-align: center;
}

Copy after login

Rendering:

Comparison results:

Because scrolling on the iPhone has a spring effect, solution 1 will not be smooth when scrolling. This situation will not occur in Option 2, and the scrolling will be smooth.

Option 2 is a better scroll view solution that I have summarized so far.
