子网格未填充

Question

我试图在不使用subgridurl的情况下用json数据填充子网格(因为这将调用每行扩展的页面)。但我得到错误:"t.rows is undefined"(在grid.base.js)。代码如下:使用的模块版本:

1. jquery-1.6.2.js
2. jqGrid 3.3.2

提前感谢。

        jQuery(gridID).jqGrid({
            url: dataURL,
            datatype: "json",
            colNames: ['ID', 'FirstName', 'LastName', 'Address1', 'Address2', 'City', 'Country'],
            colModel: [
                    { name: 'id', width: 200, sortable: false },
                    { name: 'firstName', width: 200, sortable: false, editable: true, edittype: 'select', editoptions: { value: { 1: '1', 2: '2', 3: '3'}} },
                    { name: 'lastName', width: 200, sortable: false, hidden: true },
                    { name: 'address1', width: 200, sortable: false, hidden: true },
                    { name: 'address1', width: 200, sortable: false, hidden: true },
                    { name: 'city', width: 200, sortable: false, hidden: false},
                    { name: 'country', width: 200, sortable: false, hidden: false}

            colModel: [

        jQuery("#mygrid").jqGrid('#mygrid', '#pager2', { edit: false, add: false, del: false });

错误" .rows is undefined"通常意味着您使用了错误的HTML片段的网格。例如，如果您使用<div>而不是<table>，则会出现错误。

此外，我强烈建议您升级到当前的jqGrid版本4.1.2。今天使用jqGrid 3.3.2，特别是与相对较新的jQuery 1.6.2版本一起使用，可能会出现问题。这就像试图在新汽车上使用30年的旧汽油一样。
