我已在视图中显示，但无法将其存储在本地存储中以供脱机提议。如果我出错，则无法获取它。您创建的记录应与

localStore.add(rec);

非常感谢。非常感谢。如果我有word的定义，如何在localstorage中存储并显示在Ext.XTemplate上。你有什么想法吗。我的JSON看起来像这个有定义的词。@Google\u Android\u爱好者。。这就是你在onlineStore.getProxy（）中所做的。在（'exception'，function（）{..}）上，如果你的应用程序不在线，你可以在新闻列表中设置localStore。我尝试了以下操作：message:record.data.message，definition:record.data.definitions.definition，ratings:“红色”。这里的消息工作正常，在statis中的评级也正常，但如果有定义，它不起作用，请帮助我。@Google\u Android\u爱好者问一个新问题，并给出明确解释或更新此问题
