service portal widgets: use pre to display data.events as a JSON object

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 )){...

insert line break in gs.addInfoMessage

insert line break in gs.addInfoMessage //--<br/> rather than \r\n (\r\n\ works in work_notes) var sMsg = 'line 1<br/>' ; sMsg = sMsg + 'line 2<br/>' ; sMsg = sMsg + 'line 3' ; gs . addInfoMessage ( sMsg ); //--seems to do the trick!

Code a pause/wait - gs.sleep or gs.wait alternative, pause script for specified seconds (timer)

Code a pause/wait - gs.sleep / gs.wait alternative, pause script for specified seconds (timer) e.g. 10 seconds: do_sleep ( 10000 ); function do_sleep ( milliseconds ) { var start = new Date (). getTime (); for ( var i = 0 ; i < 1e7 ; i ++) { if (( new Date (). getTime () - start ) > milliseconds ){ gs . print ( 'waking up!' ); break ; } } }
