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>
</view>
</view>
</view>
二、WXSS中
.menu-box {
position: fixed;
bottom: 40vw;
right: 30rpx;
width: 100rpx;
padding-bottom: 100rpx;
}
.menu-box .navbar {
z-index: 1000;
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 {
padding: 25rpx;
width: 100%;
height: 100%;
box-sizing: border-box;
}
.menu-box .navbar>.btn>.line {
height: 6rpx;
background-color: white;
margin: 0px 2rpx 6rpx 2rpx;
border-radius: 6rpx;
}
.menu-box .navbar>.btn>.title {
font-size: 20rpx;
}
.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 {
z-index: 100;
background-color: rgba(0, 0, 0, 0.6);
margin-bottom: 20rpx;
border-radius: 50%;
height: 100rpx;
line-height: 100rpx;
position: absolute;
width: 100rpx;
height: 100rpx;
margin-left: auto;
margin-right: auto;
opacity: 0;
font-size: 0rpx;
color: red;
}
.menu-box .menu>view text{
display: inline-block;
position: absolute;
text-align: center;
width:100%;
height: 100%;
color: white;
z-index: 10000;
font-size: 25rpx;
}
三js中

//end 第二个按钮
//start 第三个按钮
