Use 'this' keyword as a selector

I would use the selector of my event to put in my function, but it doesn't work.

I already try some tricks I'll show in the following code.

// the actual code
$('#voyages').on('click', function() {
  if (continentOuvert == false) {
    $('#voyages i.fas.fa-arrow-up').show(500);
    $('#voyages i.fas.fa-arrow-down').hide();

// the functions I try to make
function arrowUp() {
  $('this i.fas.fa-arrow-up').show(500);
  $('this i.fas.fa-arrow-down').hide();

// or
function arrowUp() {
  $(this + ' i.fas.fa-arrow-up').show(500);
  $(this + ' i.fas.fa-arrow-down').hide();

Nothing happens, I think I didn't do right.

Thanks for your help.

You can use the find method:


Use, describing an action or state of affairs that was done repeatedly or existed for a period in the past. use, employ, utilize mean to put into service especially to attain an end. use implies availing oneself of something as a means or instrument to an end. willing to use any means to achieve her ends employ suggests the use of a person or thing that is available but idle, inactive, or disengaged. looking for better ways to employ their skills utilize may suggest the discovery of a new, profitable, or practical use for something. an old wooden bucket utilized as a planter

As already mentioned $(this) cannot be a selector because it's an object not a string. As an alternative you can use $( which points to the clicked element (ie .voyages), always pass the Event Object (it's the e variable in the demo). .toggleClass() will streamline your code. Also jQuery is flexible so do not use #id use .class as much as possible.

$('.voyages').on('click', function(e) {
  var icon = $('.fas');
button {
  cursor: pointer;
  font-size: 24px
<link href="" rel="stylesheet" crossorigin="anonymous">

<button class='voyages'>Voyages <i class='fas fa-arrow-up'></i></button>

<script src=""></script>

Thanks you for all your reply. I finally use this code :

function arrowUp(id) {
            $(id + ' i.fas.fa-arrow-up').show(500);
            $(id + ' i.fas.fa-arrow-down').hide();

  • You should not use this + string/class names in your arrowUp function, as this is an object and doing so will not give you any reference but only a very vague string like [object]strstrstr
  • A tip, do console.log( $(this).find('i.fas.fa-arrow-up') ) in your code and checl in browser console what element you get by that. this will help you to understand what the code is doing / selecting
  • Alternative syntax: $("i.fas.fa-arrow-up", this).show(500);
