<script>

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

注意： 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)
