ServiceNow Code a 'cancel and copy to new change type' ui action

typical usage:

- the change is at change manager approval stage, and the change manager wishes to reject the change due to the wrong change type having been selected. The original change will be cancelled, and the fields copied to a new change. As part of the copy the user will be presented with a dialog to select the new change

via UI Action

UI Action code:

condition:

gs.hasRole('change_manager') && ( gs.getUser().isMemberOf('Change Management') || gs.hasRole('admin') ) && ChangeUtils.isCopyChangeEnabled(current)

script:

function confirmAction() {
    var gmConfirm = new GlideModal('confirm_change_cancel_copy');
    gmConfirm.setTitle('Confirm your cancellation!');
    gmConfirm.setPreference('title', getMessage('chg.cancel_copy_warning_msg'));
    gmConfirm.setPreference('warning', 'true');
    gmConfirm.setPreference('onPromptComplete', OnCopyChangeClick);
    gmConfirm.render();
}

function OnCopyChangeClick() {
    function addParam(form, name, val) {
        var inp = cel('textarea', form);
        inp.name = name;
        inp.value = val;
    }

    cancelCurrentChange();
    var srcSysId = g_form.getUniqueValue();

    var ga = new GlideAjax('ChangeUtils');//--might need to take a copy to add new function
    ga.addParam('sysparm_name', 'getChangeQueryParams');
    ga.addParam('sysparm_src_sysid', srcSysId);
    ga.addParam('sysparm_new_chg_type', g_scratchpad.new_chg_type);
    ga.setWantSessionMessages(true);
    ga.getXMLAnswer(function (queryParam) {
        if (queryParam) {
            var gotoURL = new GlideURL('CopyChangeRelatedLists.do');
            gotoURL.setEncode(false);
            gotoURL.addToken();
            gotoURL.addParam('srcSysID', srcSysId);
            gotoURL.addParam('newSysID', '$sys_id');
            gotoURL.addParam('sysparm_returned_action', '$action');

            var form = cel('form', document.body);
            hide(form);
            form.method = "POST";
            form.action = g_form.getTableName() + ".do";
            if (typeof g_ck != 'undefined' && g_ck != "")
                addParam(form, 'sysparm_ck', g_ck);
            addParam(form, 'sys_id', '-1');
            addParam(form, 'sysparm_query', queryParam);
            addParam(form, 'sysparm_goto_url', gotoURL.getURL());
            form.submit();
        }
    });
}

function cancelCurrentChange() {
    // new ChangeRequestStateHandler(current).moveTo("canceled");
    var ga = new GlideAjax('GlideRecordUtil'); //--might need to take a copy to add new function
    ga.addParam('sysparm_name', 'setFieldsInRecordInTable');
    ga.addParam('sysparm_table_name', g_form.getTableName());
    ga.addParam('sysparm_record_sys_id', g_form.getUniqueValue());
    ga.addParam('sysparm_field_names', 'state,close_code,close_notes');
    var close_notes = getMessage('chg.cancel_copy_close_notes');
    ga.addParam('sysparm_field_values', '4,canceled,'+close_notes); // Set state of current change to 'Cancelled'
    ga.getXML(function(response) {});
}

ServiceNow check for null or nil or empty (or not)

Haven't tested these all recently within global/local scopes, so feel free to have a play! option 1 use an encoded query embedded in the GlideRecord , e.g. var grProf = new GlideRecord ( 'x_cls_clear_skye_i_profile' ); grProf . addQuery ( 'status=1^ owner=NULL ' ); grProf . query (); even better use the glideRecord addNotNullQuery or addNullQuery option 2 JSUtil.nil / notNil (this might be the most powerful. See this link ) example: if ( current . operation () == 'insert' && JSUtil . notNil ( current . parent ) && ! current . work_effort . nil ()) option 3 there might be times when you need to get inside the GlideRecord and perform the check there, for example if the code goes down 2 optional routes depending on null / not null can use gs.nil : var grAppr = new GlideRecord ( 'sysapproval_approver' ); var grUser = new GlideRecord ( 'sys_user' ); if ( grUser . get ( 'sys_id' , current . approver )){
