error when refreshing

i'm using a html and javascript file that embeds a svg
the page loads fine, but when you refresh the page it makes a runtime error.
any1 know whats going on?

Hi,

hmm, I'm not sure what the problem could be. I think we will need to see the javascript and SVG. And name your browser.

Learn SVG - http://learnsvg.com

The file is pretty big, but here is the entire javascript section:

<script type="text/javascript">
var svgDoc = document.theSVG.getSVGDocument();
var nodes = svgDoc.getElementsByTagName("circle");
svgDoc.rootElement.addEventListener("SVGZoom", syncCircle, false);

function toggle_circles(checkbox) {
if(checkbox.checked) showcircles = 'hidden';
else showcircles = 'visible';

for(i=0; i<nodes.length; i++)
nodes.item(i).setAttributeNS(null,'visibility', showcircles);
}

function syncCircle()
{
var s = 1/svgDoc.rootElement.currentScale;
for(i=0; i<nodes.length; i++)
{
nodes.item(i).setAttribute("r", .0005*s);
}
}
</script>

Hi, I have a similar problem refreshig a SVG document. First I open it in IE, then, I modify it with a external java class, then, I refresh the SVG document and I dont know if the IE browser or the ASV6 doesnt work well. Only some parts are refreshed and other some arent even drawn. I really dont know who is causing this problem.

Please I need some help with this ...


Thanks ...

Mine has a problem even without any modifications.
If you load the page and then, without doing anything else, hit refresh, it'll give an error.

The file is pretty big, but here is the entire javascript section:

<script type="text/javascript">
var svgDoc = document.theSVG.getSVGDocument();
var nodes = svgDoc.getElementsByTagName("circle");
svgDoc.rootElement.addEventListener("SVGZoom", syncCircle, false);

function toggle_circles(checkbox) {
if(checkbox.checked) showcircles = 'hidden';
else showcircles = 'visible';

for(i=0; i<nodes.length; i++)
nodes.item(i).setAttributeNS(null,'visibility', showcircles);
}

function syncCircle()
{
var s = 1/svgDoc.rootElement.currentScale;
for(i=0; i<nodes.length; i++)
{
nodes.item(i).setAttribute("r", .0005*s);
}
}
</script>

Same problem here. The curious thing is, sometimes it actually does work.
My guess is that this is some kind of race condition. The page and the plugin load the content concurrently, but the plugin has to be finished loading for the HTML page to access the document root. (just a thought) Is there a way to ensure that the plugin has finished parsing?
