How to read the second element of a continuously updated table?

Question

JavaScript

Through this code I get the value (number) from the table:

var temperature = $('table#DataTables_Table_0 tr:eq(1) td:eq(6)').text();

The table is updated regularly. If you specify a table line through tr:eq(1) - then sometimes the third or even fourth line can be read. But how to make the selection on the second line not through a number, but like lastChild, but only the second one?)

Answer 1

Reduce the amount of code between element selection and value output. Those. choose the value right before outputting.
