In the example, why you used (this) instead of (event.currentTarget)?

The differences between these two aren’t so clear to me.

Thanks for your help!


Is this the example you are referring to:

$('.choice').on('click', event => {



In the code above, the .siblings() method targets elements adjacent to the clicked '.choice' and removes the 'selected' class from any previously clicked '.choice' s. Then the 'selected' class is added only to the clicked '.choice' .

The above is from the instruction panel for this lesson: https://www.codecademy.com/courses/learn-jquery/lessons/traversing-the-dom/exercises/siblings-parent

Assuming this is what you are referring to, you have raised an excellent question. Someone else please correct me if I’m wrong, but the code in the example would not work as expected. The example uses arrow function syntax which means this does not refer to the DOM element that was clicked. The example should use $(event.currentTarget) in place of $(this).

Yes, this is the example I’m referring to.

I suppose the same, the example should use $(event.currentTarget) in place of $(this). I tried to do that but doesn’t work. That’s the reason of my question.

Thanks for you answer.

Could you post the code that you tried that isn’t working? I just replaced $(this) with $(event.currentTarget) in my code, and it works fine:

  $('.product-photo').on('mouseenter', function() {
  }).on('mouseleave', function() {

$(this) was working since the function doesn’t use arrow syntax, but the above code works just as well.

  $('.product-photo').on('mouseenter', () => {
  }).on('mouseleave', () => {

The above code also works using the anonymous arrow function, but the below code does not:

  $('.product-photo').on('mouseenter', () => {
  }).on('mouseleave', () => {

This code doesn’t work because of the behavior of $(this) inside an arrow function.

That’s the code I’m referring to, it’s the last example in your reply.

In fact, I tried to use ‘function()’ instead of arrow syntax and it works.

Thank you for spending time with this.

Someone mentioned this over a year ago and it still isn’t fixed. Surely it doesn’t take longer than a few hours to fix something like this?

Not unexpected from Codecademy, there are loads of issues like this (and bigger ones too!) that don’t ever seem to get fixed…

I’m on the SASS lesson currently and it’s full of bugs

@brabli @robgit28 Weird. I submitted a bug for the Emojicode Course and it was fixed in a day. :confused:
