Is there any Servicenow doc for avoid using DOM Manipulation

[Di Zhang]

Our client ask us to disable the hint using DOM Manipulation for all the fields. I want to give him some official advise

Hi @Di Zhang ,

When manipulating DOM elements, interactions often involve classes and IDs. The risk arises that ServiceNow may alter these names in a future update, potentially causing the script to no longer function as anticipated.

Also, you can take this official KB , which also talks about As per the best practises it is not recommended to use DOM Manipulation techniques in the client-side scripting : https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0954537

Hello @Di Zhang 

Maybe this could be helpful: How to hide Form Annotation until specific field condions are met

Hope this helps!
