Now I understand about HTML comments and JS - Delimiter: July 2004 Archives

The Strange Zen Of JavaScript #3: script-killer commentsThis explains why, when I was trying to make my blog pages valid, putting the one-liner javascript code in HTML comments didn't work. Well, it made the error go away, but the code never executed. :-P
This one seems like a no-brainer, but it had several of our best JS experts stumped for a good while, until we saw what was right in front of us all along.
A script for preloading images was failing. The source was similar to this (imagine 20 or more lines of unbroken script):
<script type='text/javascript'>
<!-- preload_images ('header1.gif', 'header2.gif', 'logo.gif');
//-->
</script>
Notice how the first line of script is preceded by an HTML comment delimiter. This prevented the preload_images function from running, as the JS interpreter just skipped over the entire line. For the want of a linebreak, the script was hosed.
This seems to be common when JS is generated from some backend process. The above JavaScript was generated from a server-side application written in C .
