UI Action List Field Type

ui_action_list.js

/*
There is a Field Type called "UI Action List" which displays a Link in a Field. Clicking on the Link, calls a UI Action.
The is a "complete" example on how to put this together.
*/

//Step One: Unhide the "UI Action List" Field Type
var item = '355be32bbfa00100421cdc2ecf073929';//UI Action List / glide_action_list
var gr = new GlideRecord('sys_glide_object');
gr.get(item);
gr.setValue('visible',true);
gr.update();

//Step Two: Create a Script Include to support a UI Action
/*
Name: sn_vul.DeferralSupportAJAX
Application: Vulnerability Response (Whatever is approporate)
Client callable: true
Accessible from From: All Scopes
Active: true
Note ACL: You mane need a ACL Type: "client_callable_script_include" ACL if the instance is hardened 
*/
var DeferralSupportAJAX = Class.create();
DeferralSupportAJAX.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
    getAssessmentInfo: function() {
        var instance = {};
        var sysId = this.getParameter('sysparm_sys_id');//use 'rowSysId' in client script to get
		    var ca = new GlideRecord('sn_vul_change_approval');
        ca.get(sysId);
        if (ca) {
         		instance.id = ca.assessment_instance;
			      var ai = new GlideRecord('asmt_assessment_instance');
            ai.get(ca.assessment_instance);
			      instance.type = ai.metric_type;
			    } else {
            return '';
        }
      return instance.id + "," + instance.type;

    },
    type: 'DeferralSupportAJAX'
});

//Step Three: Create a UI Action
/*
Name: View Survey
Table: Vulnerability State Change Approval [sn_vul_change_approval]
Action name: show_survey
Show update: true
Client: true
List v2 Compatable: true
Form link: true
Onclick: showResponse()

function showResponse() {
    var ga = new GlideAjax('sn_vul.DeferralSupportAJAX');
    ga.addParam('sysparm_name', 'getAssessmentInfo');

    ga.getXML(processIt);
}
function processIt(response) { //Callback function
    var answer = response.responseXML.documentElement.getAttribute("answer"); //Must use this exact line
    if (answer) {
        var items = answer.split(',');

            title: "User's Response",
            iframe: url,
            width: '80%',
            height: '100%',
            onAfterLoad: function() {
                var iframe = d.getIFrameElement();
                setTimeout(function() {
                    iframe.height = parseInt(iframe.height) + 1;
                }, 0);
            }
        });
        d.render();
    }
}

//Step Four: Create a new Field of Type: "UI Action List"
/*
Table: Vulnerability State Change Approval [sn_vul_change_approval]
Column Lable:View Assessment
Column name: u_view_assessment
Active: true
Read only: true
Max length: 4000
Attributes: no_sort=true,slushbucket_ref_no_expand=true
Default value: <the sys_id of the UI Action in Step Three>
Note: This field will be blank for existing records. To backfill, add the sys_id of the UI Action to the old records
*/

//Optional: Backfill Script 
var custom_field = 'u_view_assessment';//Add your custom field name
var ui_action = '71bdcde887ed65102d0b422e0ebb35bc';//Add the sys_id of your custom UI Action
var gr = new GlideRecord('sn_vul_change_approval');
gr.addEncodedQuery('assessment_instance!=NULL^'+custom_field+'=NULL');
gr.query();
while(gr.next()){
	gr.setValue(custom_field, ui_action);
	gr.update();
}
