一页上有多个jqGrid，单击“添加"时如何识别哪个网格导航器上的按钮?
类似 http://trirand.com/blog/jqgrid/jqgrid.html 的页面 层次结构示例，但更复杂，每个网格都有添加"按钮，当用户单击添加"按钮时，我们需要处理添加的数据.
A page like http://trirand.com/blog/jqgrid/jqgrid.html Hierarchy example, but more complex, there are 'add' buttons for every grid, when user click on 'add' button, we need to handle added data.
我们还参考页面 http://www.ok-soft-gmbh.com/jqGrid/LocalFormEditing.htm 用于本地编辑，相关代码如下:
We also refer page http://www.ok-soft-gmbh.com/jqGrid/LocalFormEditing.htm for local editing, related code is below:
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.
}，
},
推荐答案
希望我能正确理解您的问题.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 引用的演示的旧代码中，我为旧答案做准备.
I hope that I understand your question correctly. You create multiple grids on the page and add navigator bar to the grids. You problem probably was in the old code of the referenced demo which I prepared for the old answer.
答案是在jqGrid 3.8.2版本的时候写的.后来表单编辑的代码发生了变化，因此 this 将被设置在 onclickSubmit 内的当前编辑网格的 DOM 上，就像所有其他 jqGrid 回调一样.因此可以使用 $(this) 来访问网格.更多最近的演示 为 jqGrid 4.4.1 创建，我为 答案.
The answer was written at the time of jqGrid version 3.8.2. Later the code of form editing was changes so that this will be set on the DOM of the current editing grid inside of onclickSubmit like inside of all other jqGrid callbacks. So one can use $(this) to access to the grid. More recent demo created for jqGrid 4.4.1, I posted for the answer.
我从两个参考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.生成的演示似乎我工作正常在 jqGrid 4.5.4 中.这是我在下面包含的代码:
I looked through the code of local format editing from two referenced answers, but the current version of jqGrid (4.5.4) contains more changes which required to adjusting the code. So I modified my demo one more time. The resulting demo seems me working correctly in jqGrid 4.5.4. It's code I includes below:
