Conditional custom variables

[ljd]

I've got a bunch of useful customvars for my products, but they don't apply to every production (more accurately, we don't have all the details for all the products).

So in my page i've got a line that says "About CUSTOMVAR:AUTHOR", with some room for an author photograph (CUSTOMVAR:AUTHORPICTURE) and a short biography (CUSTOMVAR:ABOUTAUTHOR).

So far so good. But if we don't have an author picture the web browser displays an "image not found" thingy. Is there a ittle bit JavaScript that I can use to say if(CUSTOMVAR:AUTHORPICTURE !=null) then CUSTOMVAR:AUTHORPICTURE else do nothing?

Ta,

You've not said what you keep in AUTHORPICTURE.

If it's <img src="mypic.jpg">

then use

<script language=JavaScript>
<!--
if ( 'CUSTOMVAR:AUTHORPICTURE' ) document.write( 'CUSTOMVAR:AUTHORPICTURE' );
// -->
</script>


If it's mypic.jpg

then use

<script language=JavaScript>
<!--
if ( 'CUSTOMVAR:AUTHORPICTURE' ) document.write('<img src="' + 'CUSTOMVAR:AUTHORPICTURE' + '">' );
// -->
</script>
