Verifying a record is found using GlideRecord.get

var gr = new GlideRecord(table);
if(gr.get(sys_id)) {
  // it is found
  gs.print(gr.sys_created_on);
} else {
  // it isn't found
  gs.print('record not found');
}

Keywords: GlideRecord, get

---

Using gs.nil()

// @todo
if(gs.nil(gr.variableName)) { }

gs.nil() will return true if a variable is empty

---

Force a record into an update set

var rec = new GlideRecord('table_name_of_record');
rec.get('sys_id_of_record');
//Push the record into the current update set   
var um = new GlideUpdateManager2();
um.saveRecord(rec);

Recursive function

var results = [];
var nestedCategories = ['898fc5a0db00d74074c99447db9619d8'];
getChildren(nestedCategories[0]);
searchItems();
return results;

function getChildren(sysID) {
    var gr = new GlideRecord('sc_category');
    gr.addQuery('parent', sysID);
    gr.addActiveQuery();
    gr.query();
    while(gr.next()) {
        var current = gr.sys_id.toString();
        nestedCategories.push(current);
        if(hasChildren(current)) {
            getChildren(current);
        }
    }
}

function hasChildren(sysID) {
    var gr = new GlideRecord('sc_category');
    gr.addQuery('parent', sysID);
    gr.addActiveQuery();
    gr.query();
    if(gr.next()) {
        return true;
    } else {
        return false;

CatItem API

var catalogItemJS = new sn_sc.CatItem(sc.getUniqueValue());
if (!catalogItemJS.canView())
    continue;
var catItemDetails = catalogItemJS.getItemSummary();

---

CatCategory API

categoryJS = new sn_sc.CatCategory(data.category_id);
if (!categoryJS.canView()) {
    data.error = gs.getMessage("You do not have permission to see this category");
    return;
}

---

CatalogSearch API

var items = data.items = [];
var catalog = $sp.getValue('sc_catalog');
var sc = new sn_sc.CatalogSearch().search(catalog, data.category_id, '', false, options.depth_search);
sc.addQuery('sys_class_name', 'NOT IN', 'sc_cat_item_wizard');
if (data.keywords)
    sc.addQuery('123TEXTQUERY321', data.keywords);
sc.orderBy('order');
sc.orderBy('name');
sc.query();

Get Days Ago

_checkDaysAgo: function (date) {
    //take date to find today, yesterday, etc.
    var now = gs.now() + ' 12:00:00';
    date = date.substring(0, 10) + ' 12:00:00';

    var nowDT = new GlideDateTime();
    nowDT.setDisplayValue(now);
    var dateDT = new GlideDateTime();
    dateDT.setDisplayValue(date);
    var seconds = gs.dateDiff(dateDT.getDisplayValue(), nowDT.getDisplayValue(), true);

    var days = seconds / 60 / 60 / 24;

    return days;
}

Working with GlideRecord.getRefRecord()

@todo - found in nr-fav-panel-list widget

var articleRef = gr.u_knowledge_article.getRefRecord();
item.title = articleRef.getDisplayValue('short_description') + " (" + gr.getDisplayValue('u_knowledge_article') + ")";

---

Working with Dates

Comparing if a Date is Less Than Current Date

var date = new GlideDateTime(date_field);
var now = new GlideDateTime();
if(date <= now) {
    // date is in the past
}
