外层我们用scroll-view包裹以实现加载更多和上拉刷新 bindscrolltoupper=”bindscrolltoupper” 这个属性当滑动到顶部会调用这个方法bindscrolltolower=”bindscrolltolower”这个则滑到底部会调用，起始这里还可以将头部和底部布局抽出来通过引入方式使用，就不用四个页面都写了，自己可以弄下

word.js

Page({
 data: {
  list: [],
  maxtime: '',
  loadingHidden: false
 },
 onLoad: function (options) {
  // 页面初始化 options为页面跳转所带来的参数
  //加载最新
  this.requestData('newlist');
 },

 /**
  * 上拉刷新
  */
 bindscrolltoupper: function () {
  //加载最新
  // this.requestData('newlist');
 },

 /**
  * 加载更多
  */
 bindscrolltolower: function () {
  console.log('到底部')
  //加载更多
  this.requestData('list');
 },

 /**
  * 请求数据
  */
 requestData: function (a) {
  var that = this;
  console.log(that.data.maxtime)
  wx.request({
   url: 'http://api.budejie.com/api/api_open.php',
   data: {
    a: a,
    c: 'data',
    maxtime: that.data.maxtime,
    type: '29',
   },
   method: 'GET',
   success: function (res) {
    console.log(res)
    console.log('上一页', that.data.list)
    that.setData({
     // 拼接数组
     list: that.data.list.concat(res.data.list),
     loadingHidden: true,
     maxtime: res.data.info.maxtime
    })

   }
  })
 },
 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
 }
})

 
  
  
  
  
   
    
    
     {{item.name}}
     {{item.passtime}}
    
   
   {{item.text}}
   
   
    
   
   
   
    
    
    
    
     
     点击查看全图
    
   
   
   
    
     
     {{item.ding}}
    
    
     
     {{item.cai}}
    
    
     
     {{item.repost}}
    
    
     
     {{item.comment}}
    
   
  
 

/*中间文字样式*/
.centerContent{
 margin-top: 20rpx;
 width: 100%;
 height: 600rpx;

}
/*中间浮动文字样式*/
.flexView{
display: flex;
justify-content: center;
align-items: center;
width: 100%;
height: 80rpx;
position: absolute;
z-index: 2;
top: 540rpx;
background: #000000;
opacity: 0.6

}
/*浮动文字*/
.flexText{

 font-size: 35rpx;

image.js

var detail = '../detail/detail'
Page({
 data: {
  list: [],
  maxtime: '',
  loadingHidden: false
 },
 onLoad: function (options) {
  // 页面初始化 options为页面跳转所带来的参数
  this.requestData('newlist');

 },
 /**
  * 滚动到底部时加载下一页
  */
 bindscrolltolower: function () {
  console.log('到底部')
  this.requestData('list');

 },

 /**
  * 加载数据
  */
 requestData: function (a) {
  var that = this;
  wx.request({
   url: 'http://api.budejie.com/api/api_open.php',
   data: {
    a: a,
    c: 'data',
    // 上一页的maxtime作为加载下一页的条件，
    maxtime: this.data.maxtime,
    type: '10',
   },
   method: 'GET',
   success: function (res) {
    console.log(res)
    console.log('上一页', that.datalist)
    that.setData({
     // 拼接数组
     list: that.data.list.concat(res.data.list),
     loadingHidden: true,
     maxtime: res.data.info.maxtime
    })

   }
  })
 },
 /**
  * 查看大图
  */
 lookBigPicture: function (e) {
  console.log(e);
  console.log(e.currentTarget.id)
  //图片url 对应wxml中data-url="{{item.url}}"
  var url = e.currentTarget.dataset.url;
  //获取图片高度 对应wxml中data-height="{{item.height}}"
  var height = e.currentTarget.dataset.height;
  //获取图片高度 对应wxml中data-width="{{item.width}}"
  var width = e.currentTarget.dataset.width;
  // 传参方式向GET请求
  wx.navigateTo({
   url: detail + '?' + 'url=' + url + "&height=" + height + "&width=" + width,
   success: function (res) {
    console.log(res)
   },
   fail: function (err) {
    console.log(err)
   },
  })
 },
 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
 }
})

这里主要看lookBigPicture方法 view data-url=”{{item.cdn_img}}” data-height=”{{item.height}}” data-width=”{{item.width}}”会在逻辑代码中装换成.语法使用 var url = e.currentTarget.dataset.url; 传值调转则向GET发送请求一样按照格式来就行了
