微信小程序实现分页加载数据

<block wx:for="{{dataArray}}" wx:for-item="list" wx:key="data">
    <block wx:for="{{list}}" wx:key="list">
        <view>内容</view>
    </block>
</block>

onLoad: function(){
　　this.getList();
},

//请求第一页数据
getList: function() {
    var that = this;
    var page = 0
    that.setData({
          dataArray: []
    })
    app.util.request({
          'url': '*****',
          'data': {
            page: 0, 
          },
          success: function(res) {
            var list= res.data.data
            var totalDataCount = list.length;  
            that.setData({
              ["dataArray["+page+"]"]: list,   
              page: page,     
              totalDataCount: totalDataCount   
            })
          }
        })
      },
    })
  },    
//请求下一页数据
next : function(){
  var page = that.data.page;
   page += 1;
   app.util.request({
     'url': '*****',
     'data': {
       page: page,
     },
     success: function(res) {
       var list = res.data.data;
       // 计算当前共加载了多少条数据，来证明这种方式可以加载更多数据
       var totalDataCount = that.data.totalDataCount;
       totalDataCount = totalDataCount + list.length;
       that.setData({
         ["dataArray[" + page + "]"]: list,
         page: page,
         totalDataCount: totalDataCount
       })
     }
   })
