Does anyone know how to read HTML comments with javascript?
ie. I have a section in my HTML like
<div id="test">
<!--
Some words
-->
</div>
I want to get "some words" into a javascript variable.
I need this to be cross browser compatable.
I have read books and looked on the net and I think what I want is possable but I cannot make it work.
Thanks
Ben

Hi Ben,
You can use the innerHTML property of the <div> tag like this:
alert(document.getElementById('test').innerHTML);
You'll need to do some string parsing to get rid of the comment tags, but that shouldn't be too hard.

If you just want to set aside some text, it might be easier to use the CSS display property.
<div id='test' style='display: none;'>
Some words.
</div>
<script type='text/javascript'>
// Then just access the contents of that div like this
document.getElementById('test').innerHTML;
</script>
The text in the <div> isn't visible in CSS capable browsers.
Regards,
Rich

Imar,
Thanks for the sugestion, works a treat :-)
Can't beleive I did not try that, I got distracted by trying to directly get at the comment tag itself.
Richard,
Thanks for the Sugestion. Unfortunately I can't just "hide" the text, I need it ignored completely until I want to use it.
Thanks:-)
