这是我的情景。当页面加载时,我的jqgrid v5.2.1不显示任何数据。这是设计的。用户必须手动输入网格和子网格的所有数据,或者单击按钮以json格式从服务器加载默认数据 $(“#jqGrid”)。jqGrid('setGridParam',{datatype:'local',data:dataResponse.groups})。trigger(“reloadGrid”);
用户在本地执行CRUD操作,直到数据正确为止,在这种情况下点击一个按钮,网格数据通过$(“#jqGrid”)。jqGrid('getGridParam','data')进入服务器。
编辑/删除操作可以正常加载默认数据但我在添加新记录时遇到问题。
新行的Id总是_empty(这很好,因为服务器端会生成它),但子网格中的新行不会传输到服务器。问题是如何建立主网格中新创建的行与子网格中相关行之间的关系,然后将所有内容传输到服务器进行处理?
以下是代码:

表单编辑中有一个小错误,现在已修复。感谢您帮助我们找到它们。
现在问题。
在主网格中添加数据时,添加每行的唯一ID是很自然的。由于bug而不是使用Guriddo id Generator插入一行,因此id = s_empty的插入错误。这会导致主网格中的每个插入行具有相同的ID,这是不正确的。
修复程序在GitHub中发布,您可以尝试。
我们更新了您的演示,以便在子网格中插入正确的数据。唯一的小添加是在添加模式的afterSubmit事件中,其中创建了所需的项目。
希望这能解决问题
以下是demo with the fixed version
<强>被修改强>
在服务器上,如果包含字符串'jqg',您可以分析id列,这将指出这是一个新行。子网格的相应id在userData模块中,它将主网格id与子网格数据连接
编辑2
您希望实现的一个可能的解决方案是获取主数据并使用userData属性获取子网格数据。在此之后,对主数据进行循环并像这样更新
var maindata = $("#jqGrid").jqGrid('getGridParam', 'data');
var subgrids = $("#jqGrid").jqGrid('getGridParam', 'userData');
for(var i= 0;i < maindata.length;i++) {
var key = maindata[i].id;
if(subgrids.hasOwnProperty(key) ) {
if(!maindata[i].hasOwnProperty(groupItems) ) {
maindata[i].groupItems = [];
}
maindata[i].groupItems = subgrids[key];
}
}
代码没有经过测试,但我认为你有了这个想法。
另一种方法是更新子网格的每个CRUD上的groupitems,我认为这并不难实现。
