微信小程序悬浮功能小按钮_微信小程序右下角悬浮按钮

如上图所示，废话不多说，直接上代码
一、WXML

<view class="menu-box">
  <view class="navbar {{ play?'active':'' }}">
    <view class="btn" bindtap="changePlay">
      <view class="line" animation="{{ !play?line1CloseAn:line1OpenAn }}"></view>
      <view class="line" animation="{{ !play?line2CloseAn:line2OpenAn }}"></view>
      <view class="title" animation="{{ !play?titleCloseAn:titleOpenAn }}">
        菜单
      </view>
    </view>
  </view>
  <view class="menu">
    <view animation="{{ !play?btn4Close:btn4Open }}">
      <text>我的</text>
    </view>
    <view animation="{{ !play?btn3Close:btn3Open }}">
      <text>购物</text>
    </view>
    <view animation="{{ !play?btn2Close:btn2Open }}">
      <text>个人</text>
    </view>
    <view animation="{{ !play?btn1Close:btn1Open }}">
      <text>哈哈</text>

二、WXSS中

.menu-box {
    position: fixed;
    bottom: 40vw;
    right: 30rpx;
    width: 100rpx;
    padding-bottom: 100rpx;
}

    position: absolute;
    bottom: 0rpx;
    width: 100rpx;
    height: 100rpx;
    text-align: center;
    background-color: rgba(0, 0, 0, 0.6);
    color: white;
    font-size: 0rpx;
    border-radius: 50%;
}
.menu-box .navbar>.btn {

}
.menu-box .active {
    background-color: pink;
}
.menu-box .menu{
    /* width: 100rpx; */
    height: 100rpx;
    /* overflow: hidden; */
    position: relative;
    /* margin: 0 auto; */
    bottom: -100rpx;
}
.menu-box .menu>view {
