【问题描述】:
这是我的场景。当页面加载时,我的 jqgrid v5.2.1 不显示任何数据。这是设计使然。用户要么必须手动输入网格和子网格的所有数据,要么单击按钮以通过
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,在这种情况下单击按钮,网格数据通过 $("#jqGrid").jqGrid('getGridParam', 'data') 进入服务器。
编辑/删除操作在加载默认数据时工作正常,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),但是来自子网格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的关联行之间的关系,然后将所有内容传输到服务器进行处理?
代码如下:
var mainGridPrefix = "s_";
$("#jqGrid").jqGrid({
styleUI: 'Bootstrap',
datatype: 'local',
editurl: 'clientArray',
postData: {},
colNames: ['Id', 'Group', 'Group Description', 'Markets', 'Group sort order'],

{ name: 'market', width: 200, sortable: false, editable: true, editrules: { required: true }, editoptions: { maxlength: 50 } },
{ name: 'sortOrder', width: 130, sortable: false, editable: true, formatter: 'number', formatoptions: { decimalSeparator: ".", thousandsSeparator: ',', decimalPlaces: 2 } }
],

var rows = data.rows, l = rows.length, i, item, subgrids = {};
for (i = 0; i < l; i++) {
item = rows[i];
if (item.groupItems) {
subgrids[item.id] = item.groupItems;
}
}
data.userdata = subgrids;
},
subGridRowExpanded: function (subgridDivId, rowId) {
var $subgrid = $("<table id='" + subgridDivId + "_t'></table>"),
pureRowId = $.jgrid.stripPref(mainGridPrefix, rowId),
subgrids = $(this).jqGrid("getGridParam", "userData"),
subgridPagerId = subgridDivId + "_p";
$("#" + $.jgrid.jqID(subgridDivId)).append($subgrid).append('<div id=' + subgridPagerId + '></div>');
$subgrid.jqGrid({

【问题讨论】:
-
主网格的关键行是id,但是子网格的哪个字段连接到主id字段?
-
在代码中添加行被禁用 - 用户如何在网格和子网格中添加记录?或者这是一个应该同步工作的任务
-
在此处发布之前,我忘记启用添加功能。假设 add 设置为 true 如何链接主网格和子网格,以便用户可以添加行并发布到服务器?
