Office js outlook桌面客户端中的本地存储

我们可以在outlook桌面客户端中使用localstorage吗

在调试outlook web加载项期间，（存储）类型始终返回undefined。发生这种情况是因为localhost吗

我知道我可以使用ROM设置而不是本地存储，但数据超过31kb

如果您需要任何信息，请告诉我。

您应该能够使用“window.localStorage”。一堆插件（比如脚本实验室）一直在运行。您遇到问题了吗？

现在我可以访问它了。没有错误，我使用vs2017调试代码。我在一个页面中设置localstorage，并尝试在另一个HTML页面中访问它。但是当我尝试访问保存的存储时，它返回null。两个页面是否在同一个域上？Localstorage（在任何浏览器中，无论office加载项如何）均为每个域。两者都位于同一个域中。在从同一页面设置Localstorage后，您是否可以立即访问它？两个页面都是外接程序的一部分吗？或者一页在外接程序中，另一页在浏览器中？是的，在同一页上设置后，我可以访问它。这两个页面都是同一加载项的一部分
