没有网络问题，所有需要的ressources正确加载..也尝试没有def的url，在这种情况下，extjs得到yahooui cdn上的swf，同样的问题
No network problem, all needed ressources are correctly loaded .. also tried with no def of the url, in this case extjs get the swf on yahooui cdn, same problem
推荐答案
你不能在本地运行没有web服务器，这就是为什么失败。设置一个本地网络服务器，它应该工作。
you cannot run it locally without a webserver, that's why it fails. Setup up a local webserver an it should work.
