我希望我能正确理解你的问题。您在页面上创建多个网格并将导航栏添加到网格。您的问题可能出在我为旧答案准备的引用演示的旧代码中。
答案是在 jqGrid 版本 3.8.2 的时候写的。后来表单编辑的代码发生了变化，因此this将在当前编辑网格的 DOM 上设置，onclickSubmit就像在所有其他 jqGrid 回调中一样。所以可以$(this)用来访问网格。为 jqGrid 4.4.1 创建的最新演示，我发布了答案。
我从两个引用的答案中查看了本地格式编辑的代码，但是当前版本的 jqGrid（4.5.4）包含更多需要调整代码的更改。所以我再次修改了我的演示。生成的演示似乎我在 jqGrid 4.5.4 中正常工作。我在下面包含的代码：
