小程序实现页面多级来回切换的示例代码

作者:德宏大魔王

这篇文章主要为大家详细介绍了小程序如何页面多级来回切换支持滑动和点击操作,文中的实现步骤讲解详细,快跟随小编一起动手尝试一下吧

第一步

首先通过swiper创建一个简单的多tab页面

通过触发pagechange1方法中的事件对currentIndex来进行赋值,又通过currentIndex的改变使前端wxml对应更改,这个部分对滑动和点击的操作都一样,无非就是使currentIndex对应到各自的位置,通过数字来决定位置

//滑动
  pagechange1: function (ee) {
    if ("touch" === ee.detail.source) {
      let currentPageIndex = this.data.currentIndex;
      currentPageIndex = (currentPageIndex + 1) % 2;
     
      this.setData({
        currentIndex: currentPageIndex,
      })
    }
  },
//点击tab时触发
  titleClick: function (e) {
    this.setData({
      //拿到当前索引并动态改变
      currentIndex: e.currentTarget.dataset.idx
    })
  },

这个部分完整代码如下:

wxml

<view>
    <!-- Tab布局 -->
    <view class='navBox'>
        <view class='titleBox' bindtap='titleClick' data-idx='0'>
            <text class="{{0 == currentIndex ? 'fontColorBox' : ''}}">安卓</text>
            <hr class="{{0 == currentIndex ? 'lineBox' : 'notLineBox'}}" />
        </view>
        <view class='titleBox' bindtap='titleClick' data-idx='1'>
            <text class="{{1 == currentIndex ? 'fontColorBox1' : ''}}">苹果</text>
            <hr class="{{1 == currentIndex ? 'lineBox' : 'notLineBox'}} " />
        </view>
    </view>
    <!-- 内容布局 -->
    <swiper class='swiperTtemBox' bindchange='pagechange1' current='{{currentIndex}}'>
        <swiper-item class='swiperTtemBox'>
            <view>内容1</view>
        </swiper-item>
        <swiper-item class='swiperTtemBox'>
            <view>内容2</view>
        </swiper-item>
    </swiper>
</view>

wxss

Page {
  /* 全局样式 */
  background: rgb(244, 245, 249);
  height: 100%;
  position: fixed;
}

.fontColorBox,
.fontColorBox1 {
  /* 文字默认颜色 */
  color: black;
}

.navBox {
  /* 顶部tab盒子样式 */
  width: 100%;
  height: 108rpx;
  background: white;
  display: flex;
  align-items: center;
  justify-content: center;
}

.navBox view:last-child {
  /* 最后一个tab标题的样式 */
  padding-left: 20%;
}

.titleBox {
  /* 未选中文字的样式 */
  color: rgb(168, 170, 175);
  font-size: 30rpx;
  display: flex;
  flex-direction: column;
  align-items: center;
}
.lineBox,.notLineBox{
  /* 选中及未选中底线共同样式 */
  width: 32rpx;
  height: 8rpx;
}

.lineBox {
  /* 选中底线样式 */
  background: rgb(43, 44, 45);
  margin-top: 16rpx;
  border-radius: 4rpx;
}

.notLineBox {
  /* 未选中底线样式 */
  background: transparent;
}

.swiperTtemBox {
  /* 底部内容样式 */
  height: 100vh;
  overflow: scroll;
  margin: 12rpx 0rpx;
  background: white;
  font-size: 28rpx;
}

js

const app = getApp()
Page({
  data: {
    currentIndex: 0, //默认第一个
  },
  pagechange1: function (ee) {
    if ("touch" === ee.detail.source) {
      let currentPageIndex = this.data.currentIndex;
      currentPageIndex = (currentPageIndex + 1) % 2;
     
      this.setData({
        currentIndex: currentPageIndex,
      })
    }
  },

  //点击tab时触发
  titleClick: function (e) {
    this.setData({
      //拿到当前索引并动态改变
      currentIndex: e.currentTarget.dataset.idx
    })
  },
})

第二步

上一步完成后,下级页面再加一个滑动页面,当内切换结束后,在做切换就是父级的切换操作

在“内容1”的view中 写入代码即可,由于父级代码只能是小于2个页面才有效,所以我们不用父级的这个滑动来做子滑动,不仅仅是因为bug的问题,这样也避免了样式和数据重复的问题

在这里我们插入wxml代码:

 <view >
    <scroll-view scroll-x="true" class="tab-h" scroll-left="{{scrollLeft}}">
        <view class="tab-item {{currentTab==0?'active':''}}"  data-current="0" bindtap="swichNav">热门</view>
        <view class="tab-item {{currentTab==1?'active':''}}" data-current="1" bindtap="swichNav">影音</view>
        <view class="tab-item {{currentTab==2?'active':''}}" data-current="2" bindtap="swichNav">阅读</view>
        <view class="tab-item {{currentTab==3?'active':''}}" data-current="3" bindtap="swichNav">游戏</view>
        <view class="tab-item {{currentTab==4?'active':''}}" data-current="4" bindtap="swichNav">福利</view>
    </scroll-view>
    <swiper class="tab-content" current="{{currentTab}}" duration="300" bindchange="switchTab"
     style="height:{{winHeight}}rpx">
        <swiper-item>
            <scroll-view scroll-y="true" class="scoll-h" >
              <view class="item-ans">
                        <view class="avatar">

js加入:

data: {
    winHeight:"",//窗口高度
    currentTab:0, //预设当前项的值
    scrollLeft:0, //tab标题的滚动条位置
    currentIndex: 0, //默认是活动项 切换
    hideModal:false//遮罩层
  },

部分完整js代码:

// pages/leftSlide/leftSlide.js

const App = getApp()

Page({
  data: {
    winHeight:"",//窗口高度
    currentTab:0, //预设当前项的值
    scrollLeft:0, //tab标题的滚动条位置
    currentIndex: 0, //默认是活动项 切换

  },

        let that=this;
        that.setData({

        });
        that.checkCor();
    },
    // 点击标题切换当前页时改变样式
    swichNav:function(e){

        console.log(cur);
        if(this.data.currentTaB==cur){return false;}
        else{
            this.setData({

            })
        }
    },
    //判断当前滚动超过一屏时,设置tab标题滚动条。
    checkCor:function(){
      if (this.data.currentTab>4){
        this.setData({
          scrollLeft:300
        })
      }else{
        this.setData({
          scrollLeft:0
        })
      }
    },
  pagechange: function (ee) {
    let that=this;
    console.log(ee.detail.source)
    if ("touch" === ee.detail.source) {
      let currentPageIndex = that.data.currentIndex;
      currentPageIndex = (currentPageIndex+1) % 2;
     
      that.setData({
        currentIndex: currentPageIndex,
      })
    }
  },
// 弹出、隐藏遮罩层

show_hideModal:function(){
  let that=this;
  that.setData({
    hideModal:true
  })

},
hideModal:function(){
  let that=this;
  that.setData({
    hideModal:false
  })
},
// 



  // 切换
  // 切换swiper-item触发bindchange事件
  pagechange: function (e) {
    // 通过touch判断,改变tab的下标值
    if ("touch" === e.detail.source) {
      let currentPageIndex = this.data.currentIndex;
      currentPageIndex = (currentPageIndex + 1) % 2;
      // 拿到当前索引并动态改变
      this.setData({
        currentIndex: currentPageIndex,
      })
    }
  },

  //点击tab时触发
  titleClick: function (e) {
    this.setData({
      //拿到当前索引并动态改变
      currentIndex: e.currentTarget.dataset.idx
    })
  },



 
  onLoad: function (options) {
    // 页面初始化 options为页面跳转所带来的参数
    var that = this; 
        //  高度自适应
        wx.getSystemInfo( {  
            success: function( res ) {  
                var clientHeight=res.windowHeight,
                    clientWidth=res.windowWidth,
                    rpxR=750/clientWidth;
              var  calc=clientHeight*rpxR-180;
                console.log(calc)
                that.setData( {  
                    winHeight: calc  
                });  
            }  
        });
  },
  onReady: function () {
    // 页面渲染完成
  },
  onShow: function () {
    // 页面显示
  },
  onHide: function () {
    // 页面隐藏
  },
  onUnload: function () {
    // 页面关闭
  }
})

样式修改为下方的即可
