微信小程序实现tab左右切换效果
置二 人气:0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 ? 'text' : ''}}" 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">
<image src="{{tabItem}}" class="img" mode="widthFix"></image>
</view>
</view>
<view class="weui-list-ft">
<view class="weui-title">
<view class="text-flow clamp-xs font-sm">{{tabItem.title}}</view>
<view class="text">
<laber>{{tabItem.text}}</laber>
<laber>{{tabItem.text}}</laber>
</view>
</view>
<view class="weui-cost">
<view>￥<laber>{{tanItem.cost}}</laber></view>

// 滚动切换标签样式
switchTab(event) {

var singeNavWidth = this.data.windowWidth / 5;
this.setData({
currentTab: cur,
navScrollLeft: (cur - 2) * singleNavWidth
});
}
})
