Simple click and mouse-over examples
SVG-SMIL allows to use user events such as a mouse click.
Something like Button.click
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"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns="http://www.w3.org/2000/svg">
<g id="Button"
transform="translate(100,100)">
<ellipse stroke-width="2" stroke="none" fill="yellow" ry="1cm" rx="2cm" >
<animate fill="freeze" dur="1s" begin="Button.click" from="1cm" to="5cm" attributeName="ry"/>
<animate fill="freeze" dur="1s" begin="Button.click" from="2cm" to="10cm" attributeName="rx"/>
</ellipse>
<text style="font-family:Arial;font-size:18;" alignment-baseline="middle" x="-1cm">Click me !</text>
</g>
</svg>
