As far as I can tell, the error is not caused by the code you have
posted, though it may be related in some way to what you haven't
posted.
Actually you are right. I am also using:
http://webfx.eae.net/dhtml/pngbehavior/pngbehavior.html
to fix png transparency in ie6. if you see the script on that page
there is a point:
// check for real change
if (src == realSrc) {
element.src = blankSrc;
return;
here the code gives error because it finds realSrc Null.
Actually I have no idea how to fix this.
Let's forget about it, because ...
.... I have also find another way to fix the transparency problem.
It's quite the same trick but probably better implemented.
I can see less flickering.
It is here:
http://blog.bjorkoy.com/2006/12/12/f...upport-in-ie6/
BUT... even with this second method my simple dynamic code does NOT
work.
There must be some interference between the dynamic code
document.body.innerHTML += "<form name='form1'
method='get'><input type='hidden' id=" + HiddenFieldID + "/></form>"
document.form1.action = submitURL;
and the component code.
But I do not know javascript well enough to fix it.
Does anybody know ??
