I do not see any good reason to convert Javascript to jQuery.

Excellent. Works great. The reason i wanted to use jQuery is because i couldn't get it to load when using it in a file in WordPress.

I'm trying to refactor this javascript from this :

var modal = document.getElementById("myModal");

// Get the image and insert it inside the modal - use its "alt" text as a caption

var img = document.getElementsByClassName("myImg");
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
  modal.style.display = "block";
  modalImg.src = this.src;
  captionText.innerHTML = this.alt;
}

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}

And this is my attempt but i am stuck :

( function( $ ) {

    var modal = $('#myModal');

    var img = $('.myImg');
    var modalImg = $('#img01');
    var captionText = $("#caption");

$("img").click(function(){
  modal.style.display = "block";
  modalImg.src = $this.src;
  captionText.innerHTML = $this.alt;
});

var span = $("close")[0];

$("span").click(function(){
  modal.style.display = "none";
});

} ( jQuery ) );
