This is how to sort a list of jQuery objects by using JavaScript's sort() function.

Here is the documentation for it.

Let's say you have a table

Sorting

To sort by the Full Name column we could do this:

var rows = $('table tbody tr');

rows.sort(function (a, b) {
  var nameA = $(a).find('.full-name').text().toUpperCase();
  var nameB = $(b).find('.full-name').text().toUpperCase();
  return (nameA < nameB) ? -1 : 1;
});

To sort by the ID column you can do this:

var rows = $('table tbody tr');

rows.sort(function (a, b) {
  var idA = parseInt($(a).find('.id').text());
  var idB = parseInt($(b).find('.id').text());
  return (idA < idB) ? -1 : 1;
});
