Getting the next N approvals

I was talking with someone they were asking how to get the next x approvals up to 10. You can't always control the environment you work in. He was trying to get the next x approvals. I came up with this script;

// start debuggingvar current = {};current.variables = {};current.variables.user = gs.getUserID();// end debuggingfunction getManager(user,display){ var m = new GlideRecord('sys_user'); if (m.get(user)) { // gs.print(m.manager.getDisplayValue() + ' : ' + m.getValue('manager')); if (display) { return m.getDisplayValue('manager'); } else { return m.getValue('manager'); } }}var approvals = [];for (var x=1; x<=10; x++) { if (x===1) { approvals.push({ x: x, name: getManager(current.variables.user,true), sys_id: getManager(current.variables.user,false) }); } else { approvals.push({ x: x, name: getManager(approvals[x-2].sys_id,true), sys_id: getManager(approvals[x-2].sys_id,false) }); } // gs.print('level ' + x + ' ' + approvals[x]);}gs.print(JSON.stringify(approvals,'',' '));
