JS:

$(function() {
    $('table').on('click', '.hide-row', function(e) {
        console.log('hidden!');
        $( this ).parent().parent().hide();
    });


  $('.add-row').click(function(e) {
    $( this ).html('Hide').removeClass('add-row').addClass('hide-row');
    $( this ).parent().parent().next().show();
  });


});

What I want to do is when the user clicks "add row" shown by another row. The button that the user clicks then turns into a button to remove the line that he is in at the same time.

What happens is that it shows a new line and hides the line that they immediately clicked on. Does anyone know what I'm doing wrong?

Thanks in advance!

click, .add-row ( ) on():

$('body').on('click', '.add-row', function(e) {

, .

$(function() {
  $('table').on('click', '.hide-row', function(e) {
    console.log('hidden!');
    $( this ).parent().parent().hide();
  });


  $('body').on('click', '.add-row', function(e) {
    $( this ).html('Hide').removeClass('add-row').addClass('hide-row');
    $( this ).parent().parent().next().show();
  });
});

Try simply using .attr ('class', 'hide-row'), making it so that you overwrite the class attribute at a time.
