微信小程序實現頭部、底部固定，中間滾動的布局

如圖：

 

 1、wxml

<view class='wraper'>
  <view class='header'>header</view>
  <view class='main'>
    <scroll-view class='main-scroll' scroll-y style="height: 100%">
      <view class='main-list'>
        <view class='card' wx:for="{{cardList}}">
          <view class='card-box'></view>
          <view>{{item.name}}</view>
          <view class='card-content'>{{item.content}}</view>
        </view>
      </view>
    </scroll-view>
  </view>
  <view class='footer'>footer</view>
</view>

2、wxss

page{
  width: 100%;
  height:100%;
}
.wraper{
  display: flex;
  flex-direction: column;
  width: 100%;
  height:100%;
}
.header{
  background: rgb(8, 117, 94);
  color: #fff;
  line-height: 100rpx;
  flex: 0 0 100rpx; /* 不放大不縮小固定100rpx */
}
.main{
  flex: 1;
  position: relative;
}
.main-scroll{
  position: absolute;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
}
.main-list{
  display: flex;
  flex-wrap: wrap;
  justify-content: space-between;
  margin-left: 2vw;
  margin-right: 2vw;
}
.card{
  width: 47vw;
  margin-top: 10rpx;
  margin-bottom: 10rpx;
}
.card-box{
  width: 100%;
  height: 200rpx;
  border-radius: 6rpx;
  background: #ccc;
}
.card-content{
  color: blue;
}
.footer{
  background: rgb(8, 117, 94);
  color: #fff;
  line-height: 100rpx;
  flex: 0 0 100rpx; /* 不放大不縮小固定100rpx */
}

3、js

Page({
 
  /**
   * 頁面的初始數據
   */
  data: {
    cardList: [
      {
        name: 'aa',
        content: 'bb'
      }, {
        name: 'aa',
        content: 'bb'
      }, {
        name: 'aa',
        content: 'bb'
      }, {
        name: 'aa',
        content: 'bb'
      }, {
        name: 'aa',
        content: 'bb'
      }, {
        name: 'aa',
        content: 'bb'
      }, {
        name: 'aa',
        content: 'bb'
      }, {
        name: 'aa',
        content: 'bb'
      },
    ]
  },
})
