How to pass sys_id to script include

[Naga Ravindra R]

Hello,

I'm leveraging one OOTB functionality but couldn't able to achieve the requirement. We have Add Ui action on incident which will help to add more incidents on a single go. Following is the problem record, In which I can add number of incidents at a time to the problem record.

But I'm unable to find the UI page in our instance.

I tried to replicate the same by creating two other tables.

Here is my UI action:

Add -- Client side -->

Below is my script:

function openVenueList(){
	var gajax = new GlideAjax("x_564970_games_sam.BulkAddVenues");
	gajax.addParam("sysparm_name","getURL");
	gajax.addParam("sysparm_sys_id", g_form.getUniqueValue());
	gajax.addParam("sysparm_parent_table", g_form.getTableName());
	gajax.getXMLAnswer(openListModalIncident);
}


function openListModalIncident(url){
	var incModal = new GlideModal('add_child_cases_to_parent');
	incModal.setTitle(getMessage("Add Venues"));
	incModal.setWidth(1200);
	incModal.setAutoFullHeight(true);
	incModal.on('beforeclose', function(){
		refreshRelatedIncidents();
	});
	ScriptLoader.getScripts('/scripts/incident/glide_modal_accessibility.js', function() {
		incModal.template = glideModalTemplate;
		incModal.renderIframe(url, function(event) {
				glideModalKeyDownHandler(event, incModal.getID());
			});
	});

	var link = document.createElement('link');
	link.rel = 'stylesheet';
	link.href = 'styles/incident_glide_modal.css';
	document.head.appendChild(link);
}

function refreshRelatedIncidents() {
	GlideList2.get(g_form.getTableName() + '.' + g_list.getRelated()).setFilterAndRefresh('');
}

Here is the script include:

getURL: function() {
        var sysId = this.getParameter(this.PARAMS.SYSID);
        var pTable = this.getParameter(this.PARAMS.PARENTTABLE);
        var url = "https://dev221704.service-now.com/x_564970_games_sam_grounds_list.do?sysparm_query=venue%3DNULL&sysparm_view=service_allocation";
     return url;
    },

I'm just hardcoding my url.

When I try to test, the ui page is showing up but I want to show both Add All and Add selected UI actions in the Pop up (SCreenshot -1).

Below is the screenshot: -> My trail

I want to have functionality like "Add All" and "Add Selected" in my ui page. How to do it?

Any inputs?
