Field Style using JavaScript Value for dot walked field that is not empty

[Leslie Hochszt1]

I am trying to use a System UI > Field Styles on the Requester field on the Incident form.  We have added a string field called Special Handling to sys_user.  I am trying to use JavaScript in the Value field.  If the Requester's Special Handling field is NOT empty, I want the Requester field background color to turn yellow. I have tried a number of variations in the value field including the following, but have been unsuccessful:

javascript: var answer = !current.caller_id.u_special_handling.nil(); answer;

javascript: var answer = current.caller_id.u_special_handling != ""; answer;

javascript: var answer = current.caller_id.u_special_handling != NULL; answer;

javascript: current.caller_id.u_special_handling != ""

Etc etc!

Anyone have any ideas? Thank you!

Hi Leslie,

Per the ServiceNow doc, the value field only affects the list field styles https://docs.servicenow.com/bundle/madrid-platform-administration/page/administer/navigation-and-ui/... 

I am afraid you will need to use client script instead, this post might be helpful for you: https://community.servicenow.com/community?id=community_question&sys_id=55a10b69db98dbc01dcaf3231f96...

The doc article you posted lists that it should be available for the form, not just the list: "Field styles allow you to declare individual CSS styles for a field in a list or form."

I considered using a client script, but the below message comes up on client scripts, so I'd rather not go against best practice:

New client-scripts are run in strict mode, with direct DOM access disabled. Access to jQuery, prototype and the window object are likewise disabled. To disable this on a per-script basis, configure this form and add the "Isolate script" field. To disable this feature for all new globally-scoped client-side scripts set the system property "glide.script.block.client.globals" to false.

If you scroll down to the Procedure part, you can see that it says "Note: The value only affects list field styles. To apply field styles on both lists and forms, leave this field blank."

Can you create a script include and try this.

Make sure the script include is accessible to all scopes and marked client callable (may be).

javascript:  var answer = new IncidentUtils.callerHasSpecialHandling(current.sys_id);  answer;

in the function you can get the caller and check the special notes field. return a true or false (boolean).

you can also test your script as a background script.
