Simple click and mouse-over examples

SVG-SMIL allows to use user events such as a mouse click. Something like allows to refer to a click event on an SVG element that has id=Button

The following SVG code fragment is part of an HTML5 file:

 <svg style="margin-left:50px;border:1px solid blue" height="300" width="300" 
      <g id="Button"
	<ellipse stroke-width="2" stroke="none" fill="yellow" ry="1cm" rx="2cm" >
	  <animate fill="freeze" dur="1s" begin="" from="1cm" to="5cm" attributeName="ry"/>
	  <animate fill="freeze" dur="1s" begin="" from="2cm" to="10cm" attributeName="rx"/>
	<text style="font-family:Arial;font-size:18;" alignment-baseline="middle" x="-1cm">Click me !</text>

Live example / source code:

Mouse over/out example

<?xml version="1.0" ?>
<svg height="200" width="500" 
  <ellipse stroke-width="2" stroke="black" fill="yellow" 
	   cx="3cm" cy="2cm" ry="1cm" rx="2cm">
    <animate fill="freeze" dur="0.1s" to="blue" from="yellow" 
		  attributeName="fill" begin="mouseover"/>
    <animate fill="freeze" dur="0.1s" to="yellow" from="blue"
		  attributeName="fill" begin="mouseout"/>

Stopping / pausing animation

Pendulum example

<?xml version="1.0" ?>

<svg xmlns="" version="1.0" 
     viewBox="0 0 300 200">
  The pendulum code was taken from The pauseAnimations method is documented in the SVG 1.1 spec:
<line x1="100" y1="0" x2="100" y2="90" stroke="black"/>
<circle cx="100" cy="90" r="10"/>
<animateTransform attributeName="transform" type="rotate" values="0,100,0;70,100,0;0,100,0;-70,100,0;0,100,0"
		  calcMode="spline" begin="0s" dur="4s" repeatCount="indefinite"/>

<g onclick="document.documentElement.pauseAnimations();" transform="translate(150 0)">
  <rect width="60" height="30" rx="10" stroke="black" fill-opacity="0.2"/>
  <text id="t" style="font:16px Arial Black;fill:white;stroke:black" transform="translate(5 20)">STOP</text>

<g onclick="document.documentElement.unpauseAnimations();" transform="translate(5 0)">
  <rect width="60" height="30" rx="10" stroke="black" fill-opacity="0.2"/>
  <text id="t2" style="font:16px Arial Black;fill:white;stroke:black" transform="translate(2 20)">START</text>
