【问题描述】：
我有一个复杂的表单，我不能使用表单序列化技术。表单内有许多字段以及动态网格（用户选择某些条件时动态生成的网格）。
我想要做的是，收集用户输入/选择 + 添加网格中可用的选定记录，然后最终用这些数据制作一个 JSON 数组，以便能够发布服务器端。
我猜，我可以使用 ExtJS 的 getCmp 函数来获取整个数据，但您可能会猜到这种方式有点难以维护。另外，我不知道用这种方式获取网格数据！
PS：代码有点长，所以我裁剪了一些部分。

【问题讨论】：
-
我的建议是从商店内的记录中读取任何数据，无论它们是什么类型。
-
亲爱的@sra 我很好奇我们如何处理选定的网格记录？这三天真的没有解决。当用户指定标准时，我可以动态创建网格存储，然后显示网格面板。我做不到最后一部分，即用整个数据制作 JsonStore。应该有简单的方法来做到这一点。我可以在服务器端处理的 JsonStore 中有哪些可用数据并不重要。
-
我不确定我是否真的明白你的目标是什么......你想要 1. 只从网格中获取选定的记录，2. 只从网格中获取修改过的记录，3. 获取所有记录或 4. 完全不同的东西。你期望什么数据结构？我的意思是你仍然需要能够将数据转换回后端的对象......？
-
亲爱的@sra，只从网格中获取选定的记录以及所有其他表单字段。从源代码可以看出，共有三个面板。当用户从第一个面板开始时，他/她选择必要的字段。当用户到达最后一个面板时，我想获取他/她选择的所有记录，包括网格。

好的，请查看我的编辑并给我反馈
