带有数据表的多个 bootstrap 选项卡。仅在其中一个选项卡上打开子行

Question

我的数据表在 2 个 bootstrap 选项卡中包含子行。子行不会始终在选项卡内打开。它们有时在第一个选项卡上打开，有时在第二个选项卡上打开。

我想在每次单击该行并打开它时创建容器。它有时在第二个打开，有时在第一个打开。它不会在两个选项卡中打开。

这是我的代码：

let json1 = [{
      "data": [

如何修复它，以便每当我单击最左侧的列时，该行以我的文本 ('test') 打开，总是出现子行？

我每次单击该行时都会创建一个容器，因为我想最终在子行中添加动态图表。

问题是因为您在循环中设置了 table。因此它只会包含对创建的 last DataTable 的引用。

要解决此问题，请从点击处理程序中的 table 元素获取 DataTable 引用：

let json1 = [{data:[{id:"1",name:"Tiger Nixon",position:"System Architect",salary:"0,800",start_date:"2011/04/25",office:"Edinburgh",extn:"5421"},{id:"2",name:"Garrett Winters",position:"Accountant",salary:"0,750",start_date:"2011/07/25",office:"Tokyo",extn:"8422"},{id:"3",name:"Ashton Cox",position:"Junior Technical Author",salary:",000",start_date:"2009/01/12",office:"San Francisco",extn:"1562"},{id:"4",name:"Cedric Kelly",position:"Senior Javascript Developer",salary:"3,060",start_date:"2012/03/29",office:"Edinburgh",extn:"6224"},{id:"5",name:"Airi Satou",position:"Accountant",salary:"2,700",start_date:"2008/11/28",office:"Tokyo",extn:"5407"}]}];
let json2 = [{data:[{id:"1",name:"Harry Potter",position:"System Architect",salary:"4,800",start_date:"2013/04/25",office:"Edinburgh",extn:"5421"},{id:"2",name:"Ron Weasley",position:"Accountant",salary:"0,777",start_date:"2011/09/25",office:"Tokyo",extn:"8422"},{id:"3",name:"Herminone Granger",position:"Junior Technical Author",salary:"5,000",start_date:"2019/01/12",office:"San Francisco",extn:"1562"},{id:"4",name:"Neville Logbottom",position:"Senior Javascript Developer",salary:"5,060",start_date:"2015/03/29",office:"Edinburgh",extn:"6224"},{id:"5",name:"Luna Lovegood",position:"Accountant",salary:"0,700",start_date:"2017/11/28",office:"Tokyo",extn:"5407"}]}];

const create_datatable = (js, tab) => {
  js.forEach(d => {
    $(`#${tab}`).DataTable({
