<view class='tab {{currentData == 1 ? "tabBorer" : ""}}' data-current = "1" bindtap='checkCurrent'>热点</view>
<view class='tab {{currentData == 2 ? "tabBorer" : ""}}' data-current = "2" bindtap='checkCurrent'>关注</view>

<swiper current="{{currentData}}" class='swiper' style="height:600px;" duration="300" bindchange="bindchange">
<swiper-item><view class='swiper_con'>这是个推荐页面</view>

<swiper-item><view class='swiper_con'>这是个热点页面</view>
<button type='primary' bindtap='ReDian'>热点进入</button>
</swiper-item>
<swiper-item><view class='swiper_con'>这是个关注页面</view></swiper-item>
</swiper>
在对应的js文件,添加以下代码:
data: {
currentData: 0,
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function (options) {
},
//获取当前滑块的index
bindchange: function (e) {
const that = this;
that.setData({
currentData: e.detail.current
})
},
//点击切换,滑块index赋值
checkCurrent: function (e) {
const that = this;
if (that.data.currentData === e.target.dataset.current) {
return false;
} else {
that.setData({
currentData: e.target.dataset.current
})
}
}
