jquery selector unable to find visible last-child

Answer 1

Try using .last() selector:

Reduce the set of matched elements to the final one in the set.

$( "table#dataTable.xLookup thead#PickerTHEAD tr th:visible" ).last()

Because your last visible child is not last child in the DOM node.

var a = $( "table#dataTable.xLookup thead#PickerTHEAD tr th:visible" ).last();

console.log(a.html());

         ...
      
      ...
