[Prasanthi1]

while executing the below, I am not getting the length of list.

var inc = new GlideRecord('incident');
inc.addActiveQuery();
inc.query();
inc.next();
var list = inc.getElements()
gs.print(list.length);

showing output: undefined

why? please explain..

Hi @Prasanthi ,

as you can see on page https://developer.servicenow.com/dev.do#!/reference/api/quebec/server_legacy/c_GlideRecordAPI there is no official method .getElements() for class GlideRecord.

What did you expect to get?

Kind regards
Maik

You are using .next method, there is no need to use this Method.

next() method returns the next element and also moves to the next element.

Try below code into Background Script, you will get Output.

var inc = new GlideRecord('incident');
inc.addActiveQuery();
inc.query();
gs.info(inc.getRowCount());

Please mark my answer as correct and close the thread so that others can also benefit.

Here my question is, while printing length of array, I am not getting the length.

Is there any error in my code... please explain my code only.

Thank you

Did you get a chance to check my comments above

getElements() would give you java object so convert that to Array and then use length

Script: This will give the length

var inc = new GlideRecord('incident');
inc.addActiveQuery();
inc.query();
inc.next();
var list = new global.ArrayUtil().convertArray(inc.getElements());
gs.info(list.length);

Actually getElements() methods returns array of objects, then why we agiain convert this to array?
