Javascript script not loading on Wordpress website

Question

So I've literally copy-pasted the code from https://codepen.io/hellokatili/pen/rVvMZb (HTML in a template, CSS in styles.css and JS using this plugin https://wordpress.org/plugins/header-and-footer-scripts/)

I added the JS script within tags.

Here is the above code from codepen (after converting from HAML to HTML and SCSS to CSS).

HTML:

  > <div class="content">   
          <script type="text/javascript"> </script>
              <div class="slider single-item">
    >     <div class="quote-container">

    >       </div>
    >       <div class="quote">

JS:

var prevButton = '<button type="button" data-role="none" class="slick-prev" aria-label="prev"><svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" version="1.1"><path fill="#FFFFFF" d="M 16,16.46 11.415,11.875 16,7.29 14.585,5.875 l -6,6 6,6 z" /></svg></button>',
    nextButton = '<button type="button" data-role="none" class="slick-next" aria-label="next"><svg version="1.1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path fill="#FFFFFF" d="M8.585 16.46l4.585-4.585-4.585-4.585 1.415-1.415 6 6-6 6z"></path></svg></button>';

$('.single-item').slick({
  infinite: true,
  dots: true,
  autoplay: true,
  autoplaySpeed: 4000,
  speed: 1000,
  cssEase: 'ease-in-out',
  prevArrow: prevButton,
  nextArrow: nextButton
});

$('.quote-container').mousedown(function(){
  $('.single-item').addClass('dragging');
});
$('.quote-container').mouseup(function(){
  $('.single-item').removeClass('dragging');
});

The HTML and CSS part work fine but the JS isn't functioning. I'm using a different JS script on the same WP site and it works just fine. Is there anything I'm missing?

Answer 1

You can also try the code by writing inside jquery ready :

(function($){
  'use strict';

    var prevButton = '<button type="button" data-role="none" class="slick-prev" aria-label="prev"><svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" version="1.1"><path fill="#FFFFFF" d="M 16,16.46 11.415,11.875 16,7.29 14.585,5.875 l -6,6 6,6 z" /></svg></button>',
        nextButton = '<button type="button" data-role="none" class="slick-next" aria-label="next"><svg version="1.1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path fill="#FFFFFF" d="M8.585 16.46l4.585-4.585-4.585-4.585 1.415-1.415 6 6-6 6z"></path></svg></button>';

    $('.single-item').slick({
      infinite: true,
      dots: true,
      autoplay: true,
      autoplaySpeed: 4000,
      speed: 1000,
      cssEase: 'ease-in-out',
      prevArrow: prevButton,
      nextArrow: nextButton
    });

    $('.quote-container').mousedown(function(){
      $('.single-item').addClass('dragging');
    });
    $('.quote-container').mouseup(function(){
      $('.single-item').removeClass('dragging');
    });

})(jQuery);

Hope this will work.

Can you try to add this jquery script in theme's footer.php for testing purpose like:

var prevButton = '', nextButton = '';

jQuery('.single-item').slick({
  infinite: true,
  dots: true,
  autoplay: true,
  autoplaySpeed: 4000,
  speed: 1000,
  cssEase: 'ease-in-out',
  prevArrow: prevButton,
  nextArrow: nextButton
});

jQuery('.quote-container').mousedown(function(){
  jQuery('.single-item').addClass('dragging');
});
jQuery('.quote-container').mouseup(function(){
  jQuery('.single-item').removeClass('dragging');
});

And also open inspect console for check any error.
