小程序写tab和swiper切换结合效果

Posted 2021-01-27 _MAN_样

实现代码如下： 
wxml页面

<scroll-view scroll-x="true" class="weui-navbar">
<block wx:for-items="{{tabs}}">
<view id="{{index}}" class="{{activeIndex == index ?\'item_on\':\'\'}} default-item" bindtap="tabClick" style="width:{{tabW}}px">
{{item}}
</view>
</block>
<view class="weui-navbar-slider" style="transform:translateX({{slideOffset}}px);"></view>
</scroll-view>
<view class="rec" />
<swiper current="{{activeIndex}}" class="swiper-box" duration="100" bindchange="bindChange">
<swiper-item class="swiper-item">
<view class="slide-view">tab0</view>
</swiper-item>
<swiper-item class="swiper-item">
<view class="slide-view">tab1</view>
</swiper-item>
<swiper-item class="swiper-item">
<view class="slide-view">tab2</view>
</swiper-item>
<swiper-item class="swiper-item">
<view class="slide-view">tab3</view>
</swiper-item>
<swiper-item class="swiper-item">
<view class="slide-view">tab4</view>
</swiper-item>
<swiper-item class="swiper-item">
<view class="slide-view">tab5</view>
</swiper-item>
<swiper-item class="swiper-item">
<view class="slide-view">tab6</view>
</swiper-item>
</swiper>

wxss样式：

page {
height: 100%;
}
view , scroll-view{
padding: 0px;
margin: 0px;
}
.weui-navbar{
width: 100%;
position: fixed;
border-bottom: 1px solid #00bba1;
box-sizing: border-box;
white-space: nowrap;
z-index: 100;
background: white;
}
.rec{
width: 100%;
height: 7%;
}
.weui-navbar .default-item{
/*width:25%;*/
display: inline-block;
text-align: center;
font-size: 32rpx;
box-sizing: border-box;
height: 7%;
padding-bottom: 20rpx;
}
.weui-navbar .item_on{
color: #00bba1;
}
.weui-navbar-slider{
position: absolute;
width: 160rpx;
height: 2px;
content:"";
background: #00bba1;
bottom: 0px;
left: 12.5rpx;
transition: transform .3s;
}
.swiper-box{
height: 900px;
border-bottom: 1px solid #d1d1d1;
}
.swiper-box .swiper-item{
text-align: center;
padding-top: 200rpx;
height: 100%;
}

 

//index.js
//获取应用实例
var app = getApp();
var mtabW;
Page({
data: {
tabs:["综合与绘画","艺术喷漆","泥塑","纸面绘画","布面绘画","中国油画","水墨画"],
activeIndex:0,
slideOffset:0,
tabW:0
},
//事件处理函数
onLoad: function () {
var that = this;
wx.getSystemInfo({
success: function (res) {
mtabW = res.windowWidth / 4; //设置tab的宽度
that.setData({
tabW:mtabW
})
}
});

},
bindViewTap: function() {
wx.navigateTo({
url: \'../logs/logs\'
})
},
tabClick:function(e){
var that = this;
var idIndex = e.currentTarget.id;
var offsetW = e.currentTarget.offsetLeft; //2种方法获取距离文档左边有多少距离
this.setData({
activeIndex:idIndex,
slideOffset:offsetW
});
},
bindChange:function(e){
var current = e.detail.current;
if((current+1)%4 == 0){

}
var offsetW = current * mtabW; //2种方法获取距离文档左边有多少距离
this.setData({
activeIndex:current,
slideOffset:offsetW
});

}

})
