查看更多信息。我也遇到了同样的问题，花了一段时间才解决 我使用的是Sencha Touch 2，它还实现了Ext.data.proxy.JsonP。Extjs 4代理在每次发送到服务器时都会自动创建一个回调参数，例如callback1、callback2。捕获此参数并将其与json一起返回非常重要，否则第二次调用它时，它将抱怨没有回调1方法 本页上的“在服务器端实现”部分
描述如何使用JsonP创建回调。我想原来的示例也会这样做。我遇到了同样的问题，花了一段时间才解决 我使用的是Sencha Touch 2，它还实现了Ext.data.proxy.JsonP。Extjs 4代理在每次发送到服务器时都会自动创建一个回调参数，例如callback1、callback2。捕获此参数并将其与json一起返回非常重要，否则第二次调用它时，它将抱怨没有回调1方法 本页上的“在服务器端实现”部分
描述如何使用JsonP创建回调。我想原始示例也会这样做。我也遇到了同样的问题，并且是服务器端代码中的一个错误。我使用的是php文件，但没有附加来自前端的回调。因此，解释jsonp请求的不同类型服务器端代码的结构很有帮助 谢谢
