[svg-developers] count all circles that are blue

[tamsvg]

Hi!

I want to count all the circles that are blue when pressing the enter
key. They become blue when 
I click on them (before this they were red). But when I jump to my
function and write out the colours
its red not blue. And so the count is 0. Why?
  
This is the code:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN"
"http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd";>

<svg width="1000" xmlns:xlink="http://www.w3.org/1999/xlink";
cursor="auto" height="800" id="svg"
     xmlns="http://www.w3.org/2000/svg"; onload="addKeyListener(evt)">

<!-- Javascript -->
    <defs>
        <script type="text/javascript"><![CDATA[
   
   function addKeyListener(evt)
   {
     var elem = evt.target;
     svgdoc = elem.ownerDocument;
     svgroot=svgdoc.rootElement;
     svgroot.addEventListener("keypress",Key,false);
   }
      function Key(evt)
   {
      var keynum=evt.charCode;
      var keychar=String.fromCharCode(keynum);
      var svgdoc = evt.target.ownerDocument;

      if (keynum==13) // ENTER key!!!
      {
        var circles = svgdoc.getElementsByTagName("circle");
        var marked=0;
        for (var i=0;i<circles.length;i++)
        {
          var el = circles.item(i);
          alert(el.getAttribute("fill"));
          if (el.getAttribute("fill") == "blue")
          {
            marked++;
          }
        }
        alert(marked);
      }
   } 

 ]]>
        </script>
    </defs>
    
    <circle r="40" id="circ1" fill="red" cx="20" cy="20">
    <set attributeName="fill" to="blue" begin="click"
dur="indefinite"/></circle>
    <circle r="40" id="circ2" fill="red" cx="200" cy="20">
    <set attributeName="fill" to="blue" begin="click"
dur="indefinite"/></circle>
    <circle r="40" id="circ3" fill="red" cx="300" cy="20">
    <set attributeName="fill" to="blue" begin="click"
dur="indefinite"/></circle>
    
</svg>

Please help me!
