像http://trirand.com/blog/jqgrid/jqgrid.html层次结构示例这样的页面，但更复杂的是，每个网格都有“添加”按钮，当用户点击“添加”按钮时，我们需要处理添加的数据。
我们还会引用页面http://www.ok-soft-gmbh.com/jqGrid/LocalFormEditing.htm进行本地编辑，相关代码如下：
jqGrid('navGrid','#pager',{},editSettings,addSettings,delSettings,
{multipleSearch:true,overlay:false, null});
addSettings = {
//recreateForm:true,
jqModal:false,
reloadAfterSubmit:false,
savekey: [true,13],
closeOnEscape:true,
closeAfterAdd:true,
onclickSubmit: function (options, postdata) {
// expected to find grid id in options, but didn't find it.
}，
}，

我希望我能正确理解你的问题。您可以在页面上创建多个网格，并将导航栏添加到网格中。问题可能出现在the referenced demo的旧代码中，我为the old answer做了准备。
答案是在jqGrid版本3.8.2时编写的。之后，表单编辑的代码发生了变化，因此this将在onclickSubmit内的当前编辑网格的DOM上设置，就像所有其他jqGrid回调内部一样。因此，可以使用$(this)来访问网格。为jqGrid 4.4.1创建了More recent demo，我发布了the answer。
我从两个引用的答案中查看了本地格式编辑的代码，但当前版本的jqGrid（4.5.4）包含了调整代码所需的更多更改。所以我再次修改了我的演示。 The resulting demo似乎我在jqGrid 4.5.4中正常工作。这是我在下面包含的代码：
