Continuously I am being informed that the value is null

Check out this code snippet:

var Ribbon = /** @class */ (function () {
    function Ribbon(svg) {
        // Code here...
    }
    
    Ribbon.prototype.init = function() {
        // Initialization code here...
    };
    
    Ribbon.prototype.updateRibbon = function() {
        // Update ribbon code here...
    };

    // More methods defined here...

    return Ribbon;
}());
var ribbon = new Ribbon(Snap('#svg'));
ribbon.init();
@import 'https://fonts.googleapis.com/css?family=Catamaran';

html, body
{
width: 100%;
height: 100%;
margin: 0;
padding: 0;
font-family: 'Catamaran', sans-serif;
}

body {
  background: #eee;
  background: linear-gradient(to left, #ddd , #eee);
}

.container
{
margin: 0;
padding: 0;
height: 100%;
width: 100%;
}

// CSS styles continue...

</code></pre><pre><code><!DOCTYPE html>
<html lang="en">
  <head>
    // Script and style imports...
  </head>
  <body>
    <div class="container">
      <script src="script.js"></script>
    <svg id="svg"></svg>
    </div>
  </body>
</html>

If you encounter any errors like this.svg is null, make sure to check the variable assignment and initialization of elements before usage. It could be due to incorrect element selectors or timing issues in your code.

Answer №1

I'm a bit confused about your intentions here. The Snap Method seems to be returning nothing because the script runs first, causing the svg tag to be removed for unknown reasons.

However, after making a slight modification to the HTML code, everything worked perfectly.

<html lang="en">
  <head>
    <meta charset="utf-8"/>

    <links href="style.css" type="text/css" rel="stylesheet">
  </head>
  <body>
    <div class="container">     
        <svg id="svg"></svg>
    </div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/snap.svg/0.4.1/snap.svg-min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.19.0/TweenMax.min.js"></script>

  </body>
</html>
