Question

Is there a better method to accomplish this task in a more effective manner?

Is there a more efficient way to achieve this code with fewer lines of code? I'm looking for a solution that avoids repetition and makes it easier to manage, especially since I plan on creating multiple instances of this. Performance is a key consideration for me.

Jquery:

$( document ).ready(function() {
        $( "#q1" ).click(function() {
            $( "#a1" ).slideToggle( "slow", function() {});
            if ($(this).hasClass('on')){
                    $(this).removeClass('on');
            }else{
                $(this).addClass('on');
            }
        });
        // Repeat similar blocks for q2, q3, and q4
    });

HTML:

<div id="faq_content">
  <div class="faq_box">
    <div class="questions" id="q1">
      <span>xyz</span>
    </div>
    <div class="answers" id="a1">
      <span>xyz</span>
    </div>
  </div>
  // Repeat similar HTML structure for q2, q3, and q4
</div>

If you're looking for a straightforward solution based on your HTML structure, consider the following approach:

$(document).ready(function() {

  // Selecting all necessary elements and assigning a click event handler:
  $("#q1, #q2").click(function() {

    // Referencing the clicked element and navigating to the next sibling with the specified selector:
    $(this)
      .next('.answers')
      .slideToggle('slow', () => {
        // Toggling a class based on whether it already exists on the element:
        $(this).toggleClass('on');
    });

  // Triggering the click event on page load to initially hide the answers:
  }).click();
});

$(document).ready(function() {
  $("#q1, #q2").click(function() {
    $(this).next('.answers').slideToggle('slow', () => {
      $(this).toggleClass('on');
    });
  }).click();
});

 ::before,
 ::after {
  box-sizing: border-box;
  margin: 0;
  padding: 0;

.faq_box {

  border-bottom-color: #000;
  cursor: pointer;
  font-size: 1.2em;
  font-weight: bold;
  transition: background-color 0.3s linear;
}

.questions::before {
  content: attr(id) ': ';
  text-transform: capitalize;
}

.answers::before {
  content: attr(id) ': ';
}

.on {

$(document).ready(function(){

    var questionClasses = $('.question');
    
    questionClasses.on('click', function(){
        var $thisQuestion = $(this);
        var answerIds =  $thisQuestion.data('id');

        $(answerIds).slideToggle("slow");

        $thisQuestion.toggleClass("active");
    });

});

Instead of repeating the same functionality for #q1, #q2... you can use classes and link them to their corresponding IDs like

<div id="#q1" class="question" data-id="#a1"></div>

. Additionally, you can set the initial state of #q1 or other questions by setting the class as "active" directly in the HTML instead of checking it in the JavaScript code. For example:

<div id="#q1" class="question active" data-id="#a1"></div>

If you have multiple handlers that share similarities, consider creating a higher-order function that returns a specific function for each handler:

function createHandler(selector) {
    return function() {
        $(selector).slideToggle("slow", function() {});
        if ($(this).hasClass('on')) {
            $(this).removeClass('on');
        } else {
            $(this).addClass('on');
        }
    }
}

Then, apply the created function like this:

$( "#q1" ).click(createHandler("#a1"))
