Examples

In the following code example, the onclick event attribute on the circle element calls the circle_click function.

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
  "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="6cm" height="5cm" viewBox="0 0 600 500" xmlns="http://www.w3.org/2000/svg" version="1.1">
  <desc>Invoke an ECMAScript function from an onclick event</desc>
  <!-- ECMAScript to change the radius with each click. -->
  <script type="application/ecmascript">
    function circle_click(evt) {
      var circle = evt.target;
      var currentRadius = circle.getAttribute("r");
      if (currentRadius == 100)
        circle.setAttribute("r", currentRadius*2);
      else
        circle.setAttribute("r", currentRadius*0.5);
    }
  </script>
  <!-- Outline the drawing area with a blue line. -->
  <rect x="1" y="1" width="598" height="498" fill="none" stroke="blue"/>
  <!-- Act on each click event. -->
  <circle onclick="circle_click(evt)" cx="300" cy="225" r="100" fill="blue"/>
  <text x="300" y="480"
        font-family="Verdana" font-size="35" text-anchor="middle">
    Click on circle to change its size
  </text>
</svg>

Notes

Remarks

Note: In addition to the attributes, properties, events, methods, and styles listed above, SVG elements also inherent core HTML attributes, properties, events, methods, and styles.

A script element is equivalent to the script element in HTML and is the place for scripts (for example, ECMAScript). Any functions that you define within any script element have a global scope across the entire current document.
