本文实例为大家分享了微信小程序实现tab左右切换展示的具体代码，供大家参考，具体内容如下
分析
1、设置data-current属性用于：点击当前项时，通过点击事件swichNav中处理e.dataset.current取到点击的目标值。
2、swiper组件的current组件用于控制当前显示哪一页
3、swiper组件绑定change事件switchTab，通过e.detail.current拿到当前页
wxml:
<view class="record-box">
<view class="nav">
<scroll-view scroll-x="true" class="navbar-box" srcoll-left="{{navScrollLeft}}"
srcoll-width-animation="{{true}}">
<block wx:for="{{recordMain}}" wx:for-index="idx" wx:for-item="navItem" wx:key="idx">
<view class="nav-item {{currentTab == idx " data-current="{{idx}}"
bindtap="switchNav">
<label>{{navItem.text}}</label>
</view>
</block>
</scroll-view>
</view>
</view>
------------------------------------------------
<view class="record-ft">
<swiper class="tab-box" current="{{currentTab}}" duration="300" bindchange="switchTab">
<swiper-item wx:for="{{[0,1,2,3]}}" wx:for-item="tabItem" wx:for-index="idx" wx:key="idx"
class="tab-cnetent">
<block wx:for="{{tabContent}}" wx:for-item="tabItem" wx:key=" ">
<view class="padding-box" bindtap="navigateUrl" data-url="/pages/index/index">
<view class="weui-list-box weui-main">
<view class="weui-list-bd">
<view class="img-box">

currentTab: 0,
navScrollLeft: 0

// 事件处理函数
onLoad: function() {
// 控制record-box随鼠标切换调整位置
if (app.globalData.userInfo) {
this.setData({
userInfo: app.globalData.userInfo,
hasUserInfo: true
})
} else if (this.data.canIUse) {
app.userInfoReadyCallback = res => {
this.setData({
userInfo: res.userInfo,
hasUserInfo: true
})
}
}
else {
wx.getUserInfo({
success: res => {
app.globalData.userInfo = res.userInfo
this.setData({
userInfo: res.userInfo,
hasUserInfo: true
})
}
})
}
wx.getSystemInfo({
success: (res) => {
this.setData({
pixelRatio: res.pixelRatio,
windowHeight: res.windowHeight,
windowWidth: res.windowWidth
})
}
})
},
// 滑动事件
// 点击标题切换当前页时改变样式
switchNav(event) {
var cur = event.currentTarget.dataset.current;
if (this.data.currentTab == cur) {
return false;
} else {
this.setData({
currentTab: cur
})
}
},
// 滚动切换标签样式
switchTab(event) {
var cur = evnet.detail.current;
var singeNavWidth = this.data.windowWidth / 5;
this.setData({
currentTab: cur,
navScrollLeft: (cur - 2) * singleNavWidth
});
}
})
