Get the index of the column name from the header, then use that in .eq().

let colName = 'ID';
let index = $(this).closest("table").find(`thead tr th:contains(${colName})`).index();
let allocationId = $(this).closest("tr").children("td").eq(index).text();

Explanation:

  • $(this).closest("table") gets the enclosing table.
  • .find(thead tr th:contains(${colName})) finds the heading cell containing the column name we care about.
  • .index() returns its position in the row.
  • $(this).closest("tr") gets the current row.
  • .children("td") returns all the <td> elements in the current row
  • .eq(index) returns the element with the same index we determined above
  • .text() returns its text content.
