Service Catalog: get display value of reference catalog variable

alert(g_form.getDisplayBox('<variable_name>').value);

note: this doesn't work in Service Portal, and not sure if it's officially supported since it doesn't appear in the GlideForm documentation!

for serviceportal, some experimentation below...

---

was having a play with GlideRecord in Service Portal view...

function onSubmit() {

    var urlString=top.location.toString();

    var res=true;

    var bPortal=false; //--loaded from Service Portal?

    if(urlString.indexOf('id=sc_cat_item')>-1){

        bPortal=true;

    }

    var itemID='';

    try{

        if (bPortal){

            itemID= g_form.getSysId(); //--service portal friendly

        }else{

            //--standard servicenow form

            itemID= gel('sysparm_id').value;

        }

    }catch (ex){

        //--

        alert('An error has occurred in the form load ' + ex.toString());

    }

   

    if (g_form.getValue('retail_owned_by')=='' || g_form.getValue('retail_assigned_to')==''){

        alert('owned by / assigned to not populated for the item selected');

        return false;

       

    }else{

        var bLaptop=false;

       

        alert(itemID);

        var displayTxt='';

        if (!bPortal){

        displayTxt=g_form.getDisplayBox('retail_kit').value.toLowerCase();

            bLaptop=(displayTxt.indexOf('lenovo')>-1);

            if (bLaptop){

                res=confirm('proceed?');

            }

            alert('return...' + res);

            return res;

           

        }else{

           

            //--SERVICE PORTAL LOGIC:

           

            var field_sysid=g_form.getValue('retail_kit');

            //--service portal view

            //--reluctantly, a gliderecord. Cant use synchronous AJAX calls and need to be able to prevent form submission
