pullupLoading is not a function和Cannot read property 'classList' of undefined问题

1.真机运行报如下错误：
Uncaught TypeError: mui(...).pullRefresh(...).pullupLoading is not a function
Uncaught TypeError: mui(...).pullRefresh(...).endPullupToRefresh is not a function
Uncaught (in promise) TypeError: mui(...).pullRefresh(...).endPulldownToRefresh is not a function

2.浏览器运行classList in undefined:
mui.js:3305 Uncaught TypeError: Cannot read property 'classList' of undefined

3.源码报错的位置：

4.代码如下：
---------------------------------app.js---------------------------------

var alarmCtrlUtil = require("./alarm_controller");//引入controller  

mui.plusReady(function() {
