Question

Function main(){

$('.skillset').hide();
$('.skillset').fadeIn(1000);
$('.projects').hide();
$('.projects-button').on('click', function(){
$('.projects').toggle();
$('.projects-button').toggleClass('active');
});
}

In that function, ALL class elements known as '.projects-button' is toggled when clicked. How can we limit this specifically to the button being clicked?

Answer 1

To limit the toggle effect to the specific '.projects' related to the clicked '.projects-button', the event handler should be updated to make use of the 'this' keyword to reference the clicked element only.

Step-by-step explanation:

The student is asking about limiting the scope of a jQuery event handler so that it affects only the element that was clicked, rather than all elements with the same class. In the provided code, the .projects-button click event handler toggles the visibility of all elements with the class .projects. To ensure that only the project related to the clicked button is toggled, you can use the this keyword within the event handler to refer to the element that received the event.

The revised code snippet would look like this:

function main(){
$('.skillset').hide();
$('.skillset').fadeIn(1000);
$('.projects').hide();
$('.projects-button').on('click', function(){
$(this).next('.projects').toggle();
$(this).toggleClass('active');
});
}

The $(this) selector accesses the specific .projects-button that was clicked, and .next('.projects') selects the immediately following sibling with the class .projects. This ensures that only that particular section of projects is toggled.
