title: Dreamweaver Image modal - script works in HTML but not as external file
body: <p>Driving me a bit insane, should be simple to figure out for all you vets.</p>
  <p>Simply, the code works in browser preview if I just delete and then paste back in the Javascript file location line <code>&lt;script src=&quot;/JS/scripts.js&quot;&gt;&lt;/script&gt;</code> (sometimes have to do this a few times) then all of a sudden it works in a browser preview but never in live view inside dreamweaver.  Code stops working again if I save all files and reload.</p>
  <p>The code seems to work fine if it's all included in the HTML file, but once I separate the script to an external file all hell breaks loose.    Any insight/help would be much appreciated. Thanks in advance.    Here is the code:</p>
  <pre><code>HTML:
  
  
  &lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
      &lt;meta name=&quot;viewport&quot; content=&quot;width=device-width, initial-scale=1&quot;&gt;
      &lt;link href=&quot;CSS/styles.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot;&gt;
      &lt;script src=&quot;JS/scripts.js&quot;&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
      
  &lt;h2&gt;Image Modal&lt;/h2&gt;
  &lt;p&gt;In this example, we use CSS to create a modal (dialog box) that is hidden by default.&lt;/p&gt;
  &lt;p&gt;We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's &quot;alt&quot; attribute as an image caption text inside the modal.&lt;/p&gt;
  
  &lt;img src=&quot;images/thumbnail4.jpg&quot; id=&quot;myImg&quot; alt=&quot;Testes123&quot; style=&quot;width:100%;max-width:300px&quot;&gt;
  
  &lt;!-- The Modal --&gt;
  &lt;div id=&quot;myModal&quot; class=&quot;modal&quot;&gt;
    &lt;span class=&quot;close&quot;&gt;&amp;times;&lt;/span&gt;
    &lt;img class=&quot;modal-content&quot; id=&quot;img01&quot;&gt;
    &lt;div id=&quot;caption&quot;&gt;&lt;/div&gt;
  &lt;/div&gt;
  
  
  &lt;/body&gt;
  &lt;/html&gt;
  
  
  JAVASCRIPT:
  
  // JavaScript Document
  // Get the modal
  var modal = document.getElementById(&quot;myModal&quot;);
  
  // Get the image and insert it inside the modal - use its &quot;alt&quot; text as a caption
  var img = document.getElementById(&quot;myImg&quot;);
  var modalImg = document.getElementById(&quot;img01&quot;);
  var captionText = document.getElementById(&quot;caption&quot;);
  img.onclick = function(){
    modal.style.display = &quot;block&quot;;
    modalImg.src = this.src;
    captionText.innerHTML = this.alt;
  }
  
  // Get the &lt;span&gt; element that closes the modal
  var span = document.getElementsByClassName(&quot;close&quot;)[0];
  
  // When the user clicks on &lt;span&gt; (x), close the modal
  span.onclick = function() { 
    modal.style.display = &quot;none&quot;;
  }
  
  
  CSS:
  
  body {font-family: Arial, Helvetica, sans-serif;}
  
  #myImg {
    border-radius: 5px;
    cursor: pointer;
    transition: 0.3s;
  }
  
  #myImg:hover {opacity: 0.7;}
  
  /* The Modal (background) */
  .modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.9); /* Black w/ opacity */
  }
  
  /* Modal Content (image) */
  .modal-content {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
  }
  
  /* Caption of Modal Image */
  #caption {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
    text-align: center;
    color: #ccc;
    padding: 10px 0;
    height: 150px;
  }
  
  /* Add Animation */
  .modal-content, #caption {  
    -webkit-animation-name: zoom;
    -webkit-animation-duration: 0.6s;
    animation-name: zoom;
    animation-duration: 0.6s;
  }
  
  @-webkit-keyframes zoom {
    from {-webkit-transform:scale(0)} 
    to {-webkit-transform:scale(1)}
  }
  
  @keyframes zoom {
    from {transform:scale(0)} 
    to {transform:scale(1)}
  }
  
  /* The Close Button */
  .close {
    position: absolute;
    top: 15px;
    right: 35px;
    color: #f1f1f1;
    font-size: 40px;
    font-weight: bold;
    transition: 0.3s;
  }
  
  .close:hover,
  .close:focus {
    color: #bbb;
    text-decoration: none;
    cursor: pointer;
  }
  
  /* 100% Image Width on Smaller Screens */
  @media only screen and (max-width: 700px){
    .modal-content {
      width: 100%;
    }
  }
  
  </code></pre>
