servicenow update multiple and using gr.attribute

 servicenow 

gliderecord 

        var gr = new GlideRecord(data['table_name']);

gr.sys_id is an object

it can be used in servicenow code like update

gr.sys_id = xxx

but it wont work when pushing to array cause its an object

var a = []

a.push(gr.sys_id) // wrong

should use a.push(gr.getValue('sys_id'))

//  update multiple:

var gr = new GlideRecord('sys_user')

gr.addQuery('name','STARTSWITH', 's');

gr.query();

gr.setValue('first_name', gs.first_name + '  updated');

gr.updateMultiple();
