java - sencha extjs GridPanel SaveState 格式

Question

我有一个场景，我想将在客户端修改的 extjs GridPanel 的列顺序保存到服务器。为此，我将 extjs gridpanel 的状态保存在 cookie 中。将此 cookie 发送到服务器端并从 cookie 中检索列顺序的值。

我的问题是gridPanel以哪种格式在cookie中保存其列顺序。我应该如何从服务器端检索它。

我在服务器端得到的键值对是这样的。那么这个值是一个什么样的对象呢？是 JSON 还是其他格式。其次，这是我实现第一段中指定的场景的方法。如果你还有其他更好的办法。请给我一些建议。任何帮助将不胜感激。

Answer 1

为什么你关心格式？您不必关心，除非您打算在服务器上修改它。

只需在客户端发送到服务器时保存 cookie 数据，并在客户端加载页面时发送即可。

如果您确实对数据的编码方式感兴趣，请查看 src/state/Provider.js - 特别是encodeValue() 和decodeValue()。
