先看效果图:
这个滑块除了可以点击上方的导航,还可以左右切换页面,随之导航也跟这切换。
实现步骤:
wxml:
<view class="content"> <view class="title"> <view class="{{currentTab==0" data-current="0" bindtap="switchNav">关注</view> <view class="{{currentTab==1" data-current="1" bindtap="switchNav">新鲜</view> <view class="{{currentTab==2" data-current="2" bindtap="switchNav">推荐</view> </view> <swiper class="swiper" bindchange="swiperchange" current="{{currentTab}}" style="height:{{winHeight}}px"> <swiper-item item-id="{{item.id}}"> 关注 </swiper-item> <swiper-item item-id="{{item.id}}"> 新鲜 </swiper-item> <swiper-item item-id="{{item.id}}"> 推荐 </swiper-item> </swiper> </view>
wxss:
.title{ display: flex; flex-direction: row; width: 100%; background-color: #ff99cc; height: 100rpx; position: fixed; z-index: 9999999999999; } .select{ width: 33%; text-align: center; height: 45px; line-height: 45px; color: white; border-bottom: 5rpx solid #ff99cc; } .default{ margin:0 auto; padding:15px; color: #666; } .swiper{ margin-top: 100rpx; }
js:
data: { currentTab:1, winWidth:0, winHeight:0 }, onLoad: function (options) { wx.getSystemInfo({ complete: (res) => { this.setData({ winWidth:res.windowWidth, winHeight:res.windowHeight }) }, }) }, switchNav(e){ console.log(e) if(this.data.currentTab==e.target.dataset.current){ return false }else{ this.setData({ currentTab:e.target.dataset.current }) } }, swiperchange(e){ this.setData({ currentTab:e.detail.current }) },
