Switching Symbols with JQuery

Hello, I am brand new to utilizing javascript and I'm currently experimenting with the toggle function. My goal is to create show/hide functionality while also toggling arrow icons. Specifically, I want a right arrow next to the link "More -->" and when clicked, it should change to "Less ^" with an up arrow. I am using icomoon fonts for these arrow icons.

Here is my current code. The show/hide functionality works fine, but I believe there might be a more efficient way to handle the arrow toggling. Initially, the arrow displays correctly, however, upon clicking the link, the arrow disappears and the HTML code becomes visible instead of the arrow icon. Unfortunately, I cannot share a direct link as I am working in a secure sandbox environment:

// Define text for show/hide links
var showText = 'More' + '<span class="icon-arrow-right2"></span>';
var hideText = 'Less' + '<span class="icon-arrow-up2"></span>';

// Append show/hide links to the element preceding the one with "toggle" class
$(".toggle").prev().append(' (<a href="#" class="toggleLink">' + showText + '</a>)');

// Hide all elements with the 'toggle' class
$('.toggle').hide();

$('a.toggleLink').click(function() {
  // Toggle link text based on visibility
  if ($(this).text() == showText) {
    $(this).text(hideText);
    $(this).parent().next('.toggle').slideDown('fast');
   } else {
    $(this).text(showText);
    $(this).parent().next('.toggle').slideUp('fast');
   }

Below is a snippet of my CSS:

/* Main toggle */
.toggle { 
  font-size: 14px;
  line-height: 20px;
  font-family: "HelveticaNeue", "Helvetica Neue", Helvetica, Arial, sans-serif;
  background: #ffffff;
  margin-bottom: 10px;
  padding: 5px;
  border: 1px solid #e5e5e5;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  border-radius: 5px; 
}

/* Adding a right arrow to the More text */
.icon-arrow-right2:before {
  content: "\ea3c";
}

/* Adding an Up arrow to Less text */
.icon-arrow-up2:before {
  content: "\ea3a";
}

Thank you for taking the time to review and provide feedback!

To manage changes in display and style upon clicking, utilize the functions toggle() and toggleClass().

For instance:

// Clicking on toggleLink will trigger toggling classes/text.
$('.toggleLink').click(function () {
    
    /*
      Determine if the showText class also includes the hide class. This can be utilized
      to toggle text. Another way is by using the :visible selector on what we're hiding
      and showing, for example:
        $('.showHide:visible')
    */
    if ($('.showText').hasClass('hide')) {
        /*
          Note the use of .text() over .html(). To insert inline html,
          use .html(). Using .text() will render plain text.
        */
        $('.showText').text("Less");
    } else {
        $('.showText').text("More");
    }
    
    /*
      Here, .toggleClass() is used in two ways. With one specified class, jQuery will
      add or remove the class accordingly. If two (or more!) classes are specified, 
      jQuery will toggle between them.
    */
    $('.showText').toggleClass('hide');
    $('.showColor').toggleClass('more less');
  
    /*
      By using .toggle(), jQuery will toggle the element's visibility. It allows nesting
      other actions within toggle as well!
    */
    $('.showHide').toggle();
});

.more {
    color: green;
}
.less {
    color: red;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="toggle">
    <div class="showText">Less</div> <a class="showColor less">Green=More, Red=Less</a>

    <br />
    <div class="showHide">Stuff</div>
</div>
<a href="#" class="toggleLink">Test</a>

The above demonstration illustrates the use of toggle() and toggleClass(), along with text replacement in an element. I suggest exploring the various functionalities of jQuery in their API documentation, and consider checking out Code Academy to grasp the fundamentals of JavaScript and other programming languages.

To achieve this, consider incorporating the toggleClass method with just one span element in your code:

<span class="toggleIcon icon-arrow-right"></span>

$('.toggleIcon').toggleClass('icon-arrow-right icon-arrow-up');
