未捕获的TypeError：$（...）。lightGallery不是一个函数

Question

when I try to click the link it shows this in browser console:

Uncaught TypeError: $(...).lightGallery is not a    function(anonymous function) @ index.html:250dispatch @ jquery.min.js:3r.handle @ jquery.min.js:3

and this is the code I used:

    $('#gallery').on('click', function() {
    $(this).lightGallery({
        dynamic: true,
        dynamicEl: [{
            "src": 'assets/images/gallery/1.jpg',
            'thumb': 'assets/images/gallery/thumbs/1.jpg',
            'subHtml': '<h4>Fading Light</h4><p>Classic view from Rigwood Jetty on Coniston Water an old archive shot similar to an old post but a little later on.</p>'
        }, {
            'src': 'assets/images/gallery/2.jpg',
            'thumb': 'assets/images/gallery/thumbs/2.jpg',
            'subHtml': "<h4>Bowness Bay</h4><p>A beautiful Sunrise this morning taken En-route to Keswick not one as planned but I'm extremely happy I was passing the right place at the right time....</p>"
        }, {
            'src': 'assets/images/gallery/3.jpg',
            'thumb': 'assets/images/gallery/thumbs/3.jpg',
            'subHtml': "<h4>Coniston Calmness</h4><p>Beautiful morning</p>"
        }]
    })
});

bear in mind I am using the Dynamic Mode in lightGallery.

1. I already included the lightGallery library before and the jQuery library before it.
2. I have tried to substitute the $ with jQuery.
3. I also tried the "semicolon solution" but with no luck.

this is the whole libraries i included:

Wooooooooooo Haaaaaa I finally solved it, and the problem was maybe with local version I have!! When I switched to the cdnjs version it worked PERFECT!!! a huge THANKS for all of you!! all I did is replace the local ones with the cdn links

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/lightgallery/1.3.2/css/lightgallery.css" />

<script src="https://cdnjs.cloudflare.com/ajax/libs/lightgallery/1.3.2/js/lightgallery.js"></script>

in the head

<link href="https://cdn.rawgit.com/sachinchoolur/lightgallery.js/master/dist/css/lightgallery.css" rel="stylesheet">

your html.

<div id="lightgallery">
  <a href="img/img1.jpg">
      <img src="img/thumb1.jpg" />
  </a>
  <a href="img/img2.jpg">
      <img src="img/thumb2.jpg" />
  </a>
</div>

in the body. at the end after jquery

<script src="https://cdn.rawgit.com/sachinchoolur/lightgallery.js/master/dist/js/lightgallery.js"></script>

   lightGallery(document.getElementById('lightgallery'));
</script>

Answer 3

I make sure, this plugin was the last script in been called. I also wrapped the code inside the ready function.

In addition, I show how to use a variant to select elements from the DOM. I'm using jQuery and running all from my local server. The sources of lightgallery are from 2018, downloaded from the repository, manually.

<script  type="text/javascript">
      $(document).ready(function() {
        $('.post img').wrap(function(){
          return "<div class='gallery' data-src='" + $( this ).attr("src") + "'></div>";
        });

        lightGallery(document.querySelector('.post'), {selector: ".gallery"});
      });
    </script>
