利用pullrefresh_with_tab.html 来做的页面
首先通过Ajax获取到数据，然后js创建动态的div，然后左右可以滑动，却无法向下滑动，报错是：
Uncaught TypeError: Cannot read property '0' of undefined mui.js:3787
网上找了方法，在#3787#那边加了个判断， 报错是不报错了，但还是不能上下滑动，就很尴尬了。
ajax获取数据和动态添加div的部分
报错部分
怎么解决呢？

通过js来获取动态添加的div的高度能获取得到， 然后左右滑动也有内容，就是不能上下滑动。
然后到mui.js 里面this.pages.length 这个就好像是<=0的。 所以报错？
