length of an array

[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..

try now

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

To check the row count you can use getRowCount().

Hi,

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);

Output:

Note: getElements() does not give list of rows details. It will return an array of GlideElement objects. Each object describes a field in the current GlideRecord.

eg:

This example retrieves a record from the incident table and shows the names of the elements (fields) in the record.
