How to create an array of arrays in javascript from gliderecord results

[anfield]

Running a fix script which returns about 300 records, each record will return 4 fields. What I want to do is put the entire contents in one array, and then for each record put that into an individual array. I know what I have below doesnt work but I wanted some guidance on how to accomplish this? 

I am creating my first array before the glide record while, based on the number of records returned, but I am trying to figure out how to populate it. The 2 nested for loops below should be fine to iterate over the data, but I need to build the nested array first.  I know how to add the data into an ordinary array with using push, but its the nested part thats giving me trouble.

The arrays should look like this:

old_computers = [

[field1 ,field2 ,field3 , field4],

[field1,field2,field3,field4]

];

I will get the field data after the glide record query like this:

var compname = grw.getValue('name');

var serial = grw.getValue('serial_number');

Fix Script:

function x_days_or_older(){

var grw = new GlideRecord('cmdb_ci_computer');
grw.addQuery('sys_class_name','=', 'cmdb_ci_computer');

// Not equal to decommissioned
grw.addQuery('operational_status', '=', 5);
grw.addQuery('discovery_source','=', 'MS SMS');
grw.addQuery('u_sccm_last_scan','!=','');

grw.addEncodedQuery('sys_class_name=cmdb_ci_computer^u_sccm_last_scanRELATIVELT@dayofweek@ago@500');

grw.query();

gs.log("sccm last scan number: " + grw.getRowCount());


var old_computers_all = new Array (grw.getRowCount());

while (grw.next()) {

for (var i=0; i < old_computers_all.length; i++){
         for (var j=0; j < old_computers_all[i].length; j++);{
                gs.log('SCCM olderscans: inner loop: ' + old_computers_all[i][j]);

}

Yes the function x_days_or_older does return the array

I don't see any issues with that loop. What is the output when you run that?

[anfield]

It just says undefined about 300 times, one for each record

In your original loop change it to:

 while (grw.next()) {
        var tempArray = []
        tempArray.push(grw.getValue('name') + '');
        tempArray.push(grw.getValue('serial_number') + ''); 
        old_computers_all.push(tempArray); 
    }

Are you sure your field names are correct?

Yes the field names are correct
