Using sysparm_query like Reference Qualifier in URL

[Alex Winkley]

This is a similar post to https://www.servicenow.com/community/developer-forum/how-if-possible-to-use-script-include-for-entir...

In our use case, we want to control the applied table filter when a module/URL is loaded using one singular function which is coded per role. Using a simple example:

var clientUtilV1 = Class.create();
clientUtilV1.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    test1: function() {
		return 'a83820b58f723300e7e16c7827bdeed2';
    },
    test2: function(){
		return 'sys_id=a83820b58f723300e7e16c7827bdeed2';
    },
    type: 'clientUtilV1'
});

If I were to go to link 1 below, the query works as intended and returns the record with sys_id=a83820b58f723300e7e16c7827bdeed2

Link 1: https://dev200523.service-now.com/incident_list.do?sysparm_query=sys_id=javascript: new global... 

(because the link gets cut off, sysparm_query uses javascript: new global.clientUtilV1().test1(); 

However, if I use the link 2 below, the query returns all records and ignores the javascript call

Link 2: https://dev200523.service-now.com/incident_list.do?sysparm_query=javascript:new global.clientU... 

(because the link gets cut off, sysparm_query uses javascript: new global.clientUtilV1().test2(); 

The function call in Link 2 drops the field in the effort of passing an entire encoded query, rather than the target value(s) for a specific field. This syntax is commonly used for Reference Qualifiers where you want to pass an entire encoded query. My question is this - is there a way to apply this Reference Qualifier like filter to sysparm_query (or another sysparm type parameter?) rather than having to do an individual script include per field? I ask because some user groups need the filter based on fields a/b/c, but other user groups need it based on fields d/e/f. For reasons I won't get into, this ideally needs to be driven all from the same URL.

Thanks!
