在菜單選擇小程序頁面的案例：
在對應的wxml文件，添加以下代碼：
<view class='topTabSwiper'>
<view class='tab {{currentData == 0 ? "tabBorer" : ""}}' data-current = "0" bindtap='checkCurrent'>推薦</view>
<view class='tab {{currentData == 1 ? "tabBorer" : ""}}' data-current = "1" bindtap='checkCurrent'>熱點</view>
<view class='tab {{currentData == 2 ? "tabBorer" : ""}}' data-current = "2" bindtap='checkCurrent'>關注</view>
</view>
<swiper current="{{currentData}}" class='swiper' style="height:600px;" duration="300" bindchange="bindchange">
<swiper-item><view class='swiper_con'>這是個推薦頁面</view>
</swiper-item>
<swiper-item><view class='swiper_con'>這是個熱點頁面</view>
<button type='primary' bindtap='ReDian'>熱點進入</button>
</swiper-item>
<swiper-item><view class='swiper_con'>這是個關注頁面</view></swiper-item>
</swiper>
在對應的js文件，添加以下代碼：
data: {
currentData: 0,
},
/**
* 生命周期函數--監聽頁面加載
*/
onLoad: function (options) {
},
//獲取當前滑塊的index
bindchange: function (e) {
const that = this;
that.setData({
currentData: e.detail.current
})
},
//點擊切換，滑塊index賦值
checkCurrent: function (e) {
const that = this;
if (that.data.currentData === e.target.dataset.current) {
return false;
} else {
that.setData({
currentData: e.target.dataset.current
})
}
}
在對應的wxss文件，添加以下代碼：
.tab{float: left; width: 33.3333%;text-align: center;padding: 10rpx 0; }
.topTabSwiper{border-top: 1px solid #ccc; border-bottom: 1px solid #ccc; zoom: 1;}
.topTabSwiper:after{content: ""; clear: both;display: block;}
.tabBorer{border-bottom: 1px solid #f00; color: #f00;}
.swiper{width: 100%;}
