Save the jQuery library in a designated variable

I am in the process of designing an FAQ page. Each question has a plus sign next to it that can be clicked to reveal the answer. I have successfully used jQuery to add a class called 'active' when a question is clicked, but since there are multiple questions on the page, I would like to find a way to avoid repeating the same code for each one. I have managed to identify the parent ID, however, I am struggling with how to store it as a variable for reuse within the jQuery script.

Here is what I am aiming to achieve:

var element = $(this).parent().parent().attr('id')

$('.expand').click(function(){ 
$('element .expand').toggleClass('active')
})

Is there a solution to this issue? When I attempt to use the 'element' variable, I receive an 'undefined' response:

$('.expand').click(function(){
    console.log(element)
});

Answer №1

If you want to locate children of a selected element, you can make use of the find() function:

var targetElement = $(this).parent().parent().attr('id');
$('.expand').click(function(){ 
    $("#" + targetElement).find('.expand').toggleClass('active');
});

Alternatively, if your intention is simply to toggle the "active" class of the clicked element, you can achieve this more efficiently without using any additional variables:

$('.expand').click(function(){ 
    $(this).toggleClass('active');
});
