This problem occurs because a child
container HTML element contains script
that tries to modify the parent
container element of the child
container. The script tries to modify
the parent container element by using
either the innerHTML method or the
appendChild method.
For example, this problem may occur if
a DIV element is a child container in
a BODY element, and a SCRIPT block in
the DIV element tries to modify the
BODY element that is a parent
container for the DIV element.
To work around this problem, write
script blocks that modify only closed
containers or that modify only the
script's immediate container element.
To do this, you can use a placeholder
to close the target container, or you
can move the script block into the
container that you want to modify.
To regenerate this behavior, you can do this -
<html>
<head>
<script type="text/javascript">
function appendToBody() {
var span = document.createElement('span');
document.body.appendChild(span);
}
</script>
</head>
<body>
<form>
<script type="text/javascript">
appendToBody();
</script>
</form>
</body>
</html>
