JavaScript accordions failing to open

I've encountered an issue with my website that includes JS accordions. Strangely, they are not opening on the live site, but they function properly on Codepen. I checked the console in Chrome and found no error messages, however, when I looked at the Firefox console, I received the same error message 7 times:

HTTP "Content-Type" of "text/html" is not supported. Load of media resource failed. homebeta.html

All candidate resources failed to load. Media load paused. homebeta.html

I'm quite puzzled by this situation, so any assistance would be greatly appreciated.

The code snippet for one of the accordions looks like this:

<dt>
  <a href="#accordion2" aria-expanded="false" aria-controls="accordion2" class="accordion-title accordionTitle js-accordionTrigger">
    <img src="http://xurbia.tk/alpha/pictures/Play_button_next_stop_music_pause.png" height=40px class="pull-left"/>
    Detox
    <img src="http://xurbia.tk/alpha/pictures/Play_button_next_stop_music_pause.png" height=40px class="pull-right"/></a>
</dt>
...

Unfortunately, the accordions do not work on the following website:

Answer №1

When developing your website, it's crucial to properly organize your JavaScript code. One effective way to do this is by using the module pattern.

The module pattern involves an immediately invoked function expression, which means that the function is called as soon as it is declared and executed.

If you place this script in the <head> section of your page, it will run before the DOM is fully loaded. This can result in issues because the JavaScript may try to interact with elements that have not yet been created.

To resolve this issue, move the <script> tag outside of the <head> and instead, place it as the last element within the <body> tag.

This adjustment ensures that the JavaScript code is executed after all necessary elements have been generated, preventing any potential conflicts.

Note that while your example functions correctly in Codepen, this is because they execute the JavaScript after the DOM has finished loading.

Answer №2

The issue you are facing is that your JavaScript code is running before the page has fully loaded. To ensure better performance, it's recommended to include your JavaScript at the bottom of the <body> tag.

Another option is to utilize an event listener that triggers after the page has finished loading, such as:

window.onload = function(){
    // Code to execute after the page has loaded
}
