<script>

The SVG script element allows to add scripts to an SVG document.

Note: While SVG's script element is equivalent to the HTML <script> element, it has some discrepancies, like it uses the href attribute instead of src and it doesn't support ECMAScript modules so far (See browser compatibility below for details)

Example

Click the circle to change colors.
<svg viewBox="0 0 10 10" height="120px" width="120px" xmlns="http://www.w3.org/2000/svg">
  <script>
    // <![CDATA[
    window.addEventListener("DOMContentLoaded", () => {
      function getColor() {
        const R = Math.round(Math.random() * 255)
          .toString(16)
          .padStart(2, "0");

        const G = Math.round(Math.random() * 255)
          .toString(16)
          .padStart(2, "0");

        const B = Math.round(Math.random() * 255)
          .toString(16)
          .padStart(2, "0");

        return `#${R}${G}${B}`;
      }

      document.querySelector("circle").addEventListener("click", (e) => {
        e.target.style.fill = getColor();
      });
    });
    // ]]>
  </script>

  <circle cx="5" cy="5" r="4" />
</svg>
