I need some helping in svg/javascript programming. I made a SVG Graphic in which the elements "Stern" should rotating by the onmouseover-event
. We are not allowed to use the svg-animations and the animation should be done by javascript. My idea is to use setAttribute("transform",...)
, but that doesn't work anyway. I google about an hour, but nothing I found there works. The function stern_rotieren is triggered by the mouse (I tested it with alert("test")
) and things like setAttribute("fill","white")
works perfectly in the same function. Only setAttribute("transform",...)
doesn't work. Maybe you can show me my failure, I'm desperate.
<defs>
<script type="text/javascript">
other functions
function stern_rotieren(){
var stern=document.getElementById("Stern");
stern.setAttribute("transform","rotate(15 500 500)");
}
</script>

symbol elements don't accept a transform attribute. It would work if you set the transform attribute on the child polygon element for instance.
