Can I read the content of a layer with NN4?

Martin Honnen,
IE4/5 allows you to read the content of a layer (or any other element)
with the
innerHTML
property. While with NN4 you can change the content of a layer with
document.layerName.document.open();
document.layerName.document.write('new content here');
document.layerName.document.close();
there is no support to read the content of a layer. So you would need
to take care of that yourself by keeping the content in a string and
document.write it. For instance
<HTML>
<HEAD>
<STYLE>
#aLayer { position: absolute; left: 20px; top: 100px; }
.big { color: white; background-color: orange; font-size: 24pt; }
</STYLE>
<SCRIPT>
var layerContent = '<SPAN CLASS="big">JavaScript.FAQTS.com<\/SPAN>';
function rewriteLayer (id, html) {
if (document.all)
document.all[id].innerHTML = html;
else if (document.layers) {
var l = document[id];
l.innerHTML = html;
l.document.open();
l.document.write(html);
l.document.close();
}
}
function initLayer () {
rewriteLayer ('aLayer', layerContent);
}
</SCRIPT>
</HEAD>
<BODY ONLOAD="initLayer()">
<DIV ID="aLayer"></DIV>
</BODY>
</HTML>
keeps the initial content in a variable and sets the content in onload.
The provided function saves the content on any rewrite so that it is
accssible.
