My first note on this is - don't do DOM manipulation from a client script. It's the number 1 cause of upgrade issues. If you reference anything from a client script as document.something, you're doing it wrong.

Second note, use a GlideAjax call to query the server and check if the sys_attachment table has one or more records with the table_name and table_sys_id corresponding to the record you want to check against. You can use a GlideAggregate query to count those records VERY fast.

See TechNow episodes 5, 6, and 33 for more information on client scripts, GlideAjax, and script includes.

Hey Chuck, 

I've been trying to do a client validation if a user has an attachment. The thing is that I need to do it on submit, and I'm working on a scoped app. The only way I found how to do it, is on the server side (business rule). Is there something I'm missing? I don't have sync GlideAjax, I don't have DOM manipulation, and I'm working on the itil view, so the SP tools are not helping. Anything I might be missing? 

Thanks!
