Help with interpreting these html lines

[Chrisj]

I see these lines in the script I'm using. Can you tell me what they mean and what they do? Thanks

 

<!--[onload_300;block=div;when [var.show_login_box]=1;comm]-->

 

<!--[onload_337;block=div;when [var.show_login_box]!=1;comm]-->

Well the <!-- is the start of an HTML comment and the --> is the end of an html comment.

 

so I would guess that it is just a comment; however, HTML comments have been used to hide javaScripts from old web browsers.

something like this.

 

<script language="JavaScript">
<!--
Here you put your JS code.
Old browsers will treat it
as an HTML comment.
//-->
</script>

so the real question is this.  do you see a script tag before the comment?
