如何在行单击时获取数据表名称答案

【问题标题】：How can i get datatable name on row click如何在行单击时获取数据表名称
【发布时间】：2025-12-19 00:15:01
【问题描述】：

我目前正在开发一个系统，它的客户端是用 Javascript 编码的，动态表来自库数据表 https://datatables.net/。

如何在行单击时获取表名？

我需要 ito 编码，因为只有一个函数用于管理多个表的创建，并且我必须从一行中的特定列中获取数据，单击以将它们放入数组中并将它们作为参数发送。

从一个单元格获取数据很容易，但是从它的 id 获取数据表的一列的所有数据（当您不知道此 id 时）在网上很难找到。

$(nomTable + " tbody").on('click', 'tr', function (e) {
        var cell = $(this).parent("td");
        var cells = cell.context.cells;
        var contextData = {
            "a": cells[0].innerText,
            "b": cells[2].innerText,
            "c": cells[3].innerText,
            "d": cells[5].innerText,
            "e": cells[6].innerText,
            "arrayOfColumnXData" : aFunction(this)
        }
    });

function aFunction(p){
...code...
}

【解决方案1】：

$(nomTable + " tbody").on('click', 'tr', function (e) {
    var cell = $(this).parent("td");
    var cells = cell.context.cells;
    var contextData = {
        "a": cells[0].innerText,
        "b": cells[2].innerText,
        "c": cells[3].innerText,
        "d": cells[5].innerText,
        "e": cells[6].innerText,
        "arrayOfColumnXData" : $(this).closest('table').attr('id')
    }
});

【解决方案2】：

您的代码可以简化如下：

 $(nomTable + ' tbody').on('click', 'tr', function(e) {
    // Get API instance of the table containing the row
    var api = $(this).closest('table').DataTable();

    // Get row data
    var data = api.row(this).data();

    var contextData = {
       "a": data[0],
       "b": data[2],
       "c": data[3],
       "d": data[5],
       "e": data[6],
       "arrayOfColumnXData" : data
   };
});

请参阅下面的示例进行演示。

$(document).ready(function() {
  $('#example').DataTable();

  $('#example tbody').on('click', 'tr', function(e) {
     var api = $(this).closest('table').DataTable();
     var data = api.row(this).data();
     var contextData = {
        "a": data[0],
        "b": data[2],
        "c": data[3],
        "d": data[5],
        "e": data[1],
        "arrayOfColumnXData" : data
    };
    
    console.log(contextData)
  });
});
