问候！
这个工具太棒了！自从我找到它以来，我一直很享受这个。
我一直面临着儿童行的一些困难。 PLS。指导我这个。感谢是否有人可以分享他们的解决方案。
我的问题：显示更改数据集的子行：
我一直在收到错误
ctx [0] .aoData [this [0]]未定义
当我尝试在数据源更改后获取子行时。通过传递参数单击按钮后获取新数据源。初始加载数据证明没有问题，但后续数据加载会产生错误。一旦调试器遇到以下代码，就会传递错误：
if (row.child.isShown()) {}
以下是我的全部代码：
function organization_GetAccountManagerDetailEarnings(purl, pstart, pend, pcontext, purl2) {
var table;
var existing_table = $('#accountManagerEarningsDataTable').dataTable();
if (existing_table != undefined) {
existing_table.fnClearTable();
existing_table.fnDestroy();
}
table = $('#accountManagerEarningsDataTable').DataTable({

d.context = pcontext;

我本来只是把它写成评论，但我没有足够的声誉。所以......
在我看来，更改数据源后，您的jQuery选择器$('#accountManagerEarningsDataTable tbody')可能不存在。您是否100％确定在更改数据源时，表格是使用<tbody>元素呈现的？我注意到您的示例HTML在<tbody>中没有#accountManagerEearningsDataTable元素，因此选择器将是未定义的。
