微信小程序中swiper实现切换
1、wxml中关键代码：
<view class="swiper-tab">
<view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">Seside1</view>
<view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">Seside2</view>
<view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">Seside3</view>
</view>
<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange">
<swiper-item>
<view>Seside1</view>
</swiper-item>
<swiper-item>
<view>Seside2</view>
</swiper-item>
<swiper-item>
<view>Seside3</view>
</swiper-item>
</swiper>
2、js代码:
//index.js
//获取应用实例
var app = getApp()
Page({
data: {
// 页面配置
winWidth: 0,
winHeight: 0,
// tab切换
currentTab: 0,
},
onLoad: function () {
var that = this;
// 获取系统信息
wx.getSystemInfo({
success: function (res) {
that.setData({
winWidth: res.windowWidth,
winHeight: res.windowHeight
});
}
});
},
// 滑动切换tab
bindChange: function (e) {
var that = this;
that.setData({ currentTab: e.detail.current });
},
// 点击tab切换
swichNav: function (e) {
var that = this;
if (this.data.currentTab === e.target.dataset.current) {
return false;
} else {
that.setData({
currentTab: e.target.dataset.current
})
}
}
})
3、css代码：
.swiper-tab{
width: 100%;
border-bottom: 2rpx solid #777777;
text-align: center;
line-height: 80rpx;
}
.swiper-tab-list{
font-size: 30rpx;
display: inline-block;
width: 20%;
color: #777777;
margin-right: 4%;
margin-left: 4%;
}
.on{
color: #da7c0c;
border-bottom: 5rpx solid #da7c0c;
}
.swiper-box{
display: block;
height: 100%;
width: 100%;
overflow: hidden;
}
.swiper-box view{
text-align: center;
}
