先上效果图:
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%; }
js代码:
//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 }); } })
