在pages文件里面创建swipertab文件夹
1.编写页面结构:swipertab.wxml
<view class="swiper-tab">
<view class="swiper-tab-list {{currentTab==0 ? \'on\' : \'\'}}" data-current="0" bindtap="swichNav">全部</view>
<view class="swiper-tab-list {{currentTab==1 ? \'on\' : \'\'}}" data-current="1" bindtap="swichNav">待支付</view>
<view class="swiper-tab-list {{currentTab==2 ? \'on\' : \'\'}}" data-current="2" bindtap="swichNav">待使用</view>
<view class="swiper-tab-list {{currentTab==3 ? \'on\' : \'\'}}" data-current="3" bindtap="swichNav">待评价</view>
<view class="swiper-tab-list {{currentTab==4 ? \'on\' : \'\'}}" data-current="4" bindtap="swichNav">退款/售后</view>
</view>
<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange">
<!-- tab一 -->
<swiper-item>
<view>全部</view>
</swiper-item>
<!-- tab二 -->
<swiper-item>
<view>待支付</view>
</swiper-item>
<!-- tab三 -->
<swiper-item>
<view>待使用</view>
</swiper-item>
<!-- tab四 -->
<swiper-item>
<view>待评价</view>
</swiper-item>
<!-- tab五 -->
<swiper-item>
<view>退款/售后</view>
</swiper-item>
</swiper>
2.设置数据:swipertab.js
//获取应用实例
var app = getApp()
Page({
/**
* 页面的初始数据
*/
data: {
/** * 页面配置*/
winWidth: 0,
winHeight: 0,
// tab切换
currentTab: 0,
},
/**
* 生命周期函数--监听页面加载
*/
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.设置样式:swipertab.wxss
.swiper-tab{
width: 100%;
text-align: center;
line-height: 80rpx;
background: linear-gradient(to right,rgb(135, 190, 235),rgb(0, 81, 255));
}
.swiper-tab-list{
font-size: 30rpx;
display: inline-block;
width: 18%;
color: white;
margin-bottom: 2px;
}
.on{
border-bottom: 5rpx solid white;
}
.swiper-box{
display: block;
height: 100%;
width: 100%;
overflow: hidden;
}
.swiper-box view{
text-align: center;
}
