微信小程序实现顶部选项卡(swiper)
纸上得来终觉浅-绝知此事要躬行 人气:0微信小程序顶部选项卡在开发中是非常常用的,下面用一点时间实现了一下。
效果图:
下面直接上代码:
wxml:
<!--pages/index/index.wxml--> <view class="swiper-tab"> <view class="tab-item {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">选项一</view> <view class="tab-item {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">选项二</view> <view class="tab-item {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">选项三</view> </view> <swiper current="{{currentTab}}" class="swiper" duration="300" style="height:{{winHeight - 30}}px" bindchange="bindChange"> <swiper-item> <view>页面一</view> </swiper-item> <swiper-item> <view>页面二</view> </swiper-item> <swiper-item> <view>页面三</view> </swiper-item> </swiper>
wxss:
/* pages/index/index.wxss */ .swiper-tab{ width: 100%; text-align: center; line-height: 80rpx; border-bottom: 1px solid #000; display: flex; flex-direction: row; justify-content: center; } .tab-item{ flex: 1; font-size: 30rpx; display: inline-block; color: #777777; } .on{ color: red; border-bottom: 5rpx solid red; } .swiper{ display: block; height: 100%; width: 100%; overflow: hidden; } .swiper view{ text-align: center; padding-top: 100rpx; }
js:
// pages/index/index.js Page({ /** * 页面的初始数据 */ data: { winWidth:0, winHeight:0, currentTab:0 }, /** * 生命周期函数--监听页面加载 */ onLoad: function (options) { var that = this; /** * 获取系统信息 */ wx.getSystemInfo({ success: function (res) { that.setData({ winWidth: res.windowWidth, winHeight: res.windowHeight }); } }); }, bindChange: function (e) { var that = this; that.setData({ currentTab: e.detail.current }); }, swichNav: function (e) { var that = this; if (this.data.currentTab === e.target.dataset.current) { return false; } else { that.setData({ currentTab: e.target.dataset.current }) } } , /** * 页面相关事件处理函数--监听用户下拉动作 */ onPullDownRefresh: function () { }, /** * 页面上拉触底事件的处理函数 */ onReachBottom: function () { }, /** * 用户点击右上角分享 */ onShareAppMessage: function () { } })
以上是实现过程,总体上没什么难度。可以参考参考。
