Answer 1

可是store没有length和record的属性。
不知道是哪里出问题了。
在线等 跪求帮忙

Answer 2

发现问题了：
 Proxy应该是proxy
但又出现了缺少分号的错误为什么js这么难调试
为什么没有人开发一个便于调试的js IDE呢

Answer 3

spket工具或者vs工具啊
把Extjs库文件放进去

Answer 4

用了vs工具调试，可是没找到问题。
项目紧，哎 着急上火
一个缺少分号错误怎么都调不出来
据网上说是编码错误？
用type: 'memory'就正常显示
用type: 'jsonp' 就会报缺少分号错误
代码就在一楼
就是没办法解决啊
