小程序分页加载

// 请求数据的函数

function loadData(currentPage = 0, pageSize = 5) {

  let res;

  // 获取数据

  // xxxxxxx

  const totalPage = Math.ceil(res.total / pageSize);

  const { list } = this.data;

  const newList = list.concat(res.data);

  this.setData({

    totalPage,

    currentPage: currentPage + 1,

    pageSize,

    list: newList

  })

}

onLoad: function() {

  this.loadData(0, 5);

}

loadMoreData: function() {

  const { currentPage, totalPage, pageSize } = this.data;

  if (currentPage >= totalPage) {

    return;

  }

  this.loadData();
