这是组件代码
<ssnew_list hiddend="false" heightd="500" id="ssnew_list"></ssnew_list>
这是页面代码，加载后不出现数据列表
这个是控制台显示，已经有数据
that.setData({ dataList: that.data.dataList }) 为什么不写成 下面这种，你发的代码别人也运行不了，arr打印出来是个什么，加入你把arr写死呢？ that.setData({ dataList: arr })ready: function () {
this.refresh();
console.log('ready')
},
这个启动后执行refresh，在调用getDate
