急急急,mui.js版本升级后上拉刷新报错了

分类:MUI
mui

之前用的是mui的1.6版本,现在升级到1.8之后,上拉刷新报错了

Uncaught TypeError: Cannot read property 'classList' of undefined at js/mui.js:2660

mui.js中的代码
_initPullupRefresh: function() {
this.pulldown = false;
this.pullPocket = this.bottomPocket;
this.pullPocket.classList.add(CLASS_BLOCK);
this.pullPocket.classList.add(CLASS_VISIBILITY);
this.pullCaption = this.bottomCaption;
this.pullLoading = this.bottomLoading;
},

报错的是这行 this.pullPocket.classList.add(CLASS_BLOCK);

请问现在上拉刷新的写法什么改变吗?
