Page({  
/*页面的初始数据*/
  data: {
      page: 1,    
      loading: false,    
      loadtxt: &#39;正在加载...&#39;,    
      list: []
  },  
  /*生命周期函数--监听页面加载*/
  onLoad: function (options) {    
  this.setData({      
  option: options
    })    
    this.getlist();
  },  
  getlist: function () {
    app.fetch.newData.result({ API_URL: app.globalData.api + &#39;getGoldFlowList.do?ipage=&#39; + this.data.page + &#39;&ipagesize=15&#39;}).then(({ data }) => {      
    if (data.object && data.object.list && data.object.list.length) {        
    let list = data.object.list;        
    for (let i = 0; i < list.length; i++) {
          list[i].c_create_datetime = app.util.formatDate(new Date(list[i].c_create_datetime));
        }        
        this.setData({
          list: this.data.list.concat(list)
        })        
        if (this.data.page == data.iTotalPage) {          
        this.setData({
            loading: true,
            loadtxt: &#39;无更多内容&#39;
          })
        } else {          
        this.setData({
            loading: false,
            loadtxt: &#39;正在加载...&#39;
          })
        }
      } else if (this.data.list.length) {        
      this.setData({
          loading: true,
          loadtxt: &#39;无更多内容&#39;
        })
      } else {        
      this.setData({
          loading: true,
          loadtxt: &#39;暂无数据&#39;
        })
      }
    }).catch(e => {      
    this.setData({
        loading: false,
        loadtxt: &#39;数据加载异常&#39;
      })
    })
  },
  /*页面上拉触底事件的处理函数*/  
  onReachBottom: function () {    
  if (!this.data.loading) {      
  this.setData({
        loading: true,
        page: this.data.page + 1
      })
      this.getlist()
    }
  }
})
