<script>

A SVG script element is equivalent to the script element in HTML and thus is the place for scripts (e.g., ECMAScript).

Any functions defined within any script element have a global scope across the entire current document.

Usage context

Categories	None
Permitted content	Any elements or character data

Example

The following code snippet demonstrates the use of the SVG script tag. In this code, we use JavaScript to change the radius of the SVG <circle> element.

<svg width="100%" height="100%" viewBox="0 0 100 100"
     xmlns="http://www.w3.org/2000/svg">
  <script type="text/javascript">
    // <![CDATA[
    function change(evt) {
      var target = evt.target;
      var radius = target.getAttribute("r");

      if (radius == 15) {
        radius = 45;
      } else {
        radius = 15;
      }

      target.setAttribute("r",radius);
   }
   // ]]>
  </script>

  <circle cx="50" cy="50" r="45" fill="green"
          onclick="change(evt)" />
</svg>
