How to stop a for loop when a JSON key pair in variable is null

[Lon Landry4]

The code below needs to stop if one of the JSON Key pairs below has a null value. The actual var maps contains many JSON Key pairs. The system needs to know if a key pair is empty then to stop the program. This code is for Workflow and is being used in the platform as opposed to portal.

I have tried combinations where I check if maps or i is null (ex. maps !=0) , but I am not doing in correct place or have my syntax incorrect.

The code should result in hardware assets being created if JSON pair does not contain a null value.

Any idea how to stop a for loop when a JSON pair inside of a variable is null or all key pairs have been actioned upon.

var maps = [

{

'asset_tag': 'first_asset_tag',

'serial_number': 'first_serial_number',

},

{

'asset_tag': 'second_asset_tag',

'serial_number': 'second_serial_number',

},

{

'asset_tag': 'third_asset_tag',

'serial_number': 'third_serial_number',

},

];

gs.info(JSON.stringify(maps, null, '\t'));

var grHardware = new GlideRecord('alm_hardware');

for (var i = 0; i < maps.length; i++) {

var map = maps[i];

gs.debug('Setting up record ' + (i + 1));

grHardware.initialize();

for (var field in map) {

gs.debug('Setting field ' + field + ' to value of variable ' + map[field] + ' (' + current.variables[map[field]] + ')');

grComputer.setValue(field, current.variables[map[field]]);

}

grHardware.install_status = '6';

grHardware = 'available';

gs.debug('Creating record ' + (i + 1));

grHardware.insert();

}

Hi @Lon Landry4,

Try something like below:

for (var i = 0; i < maps.length; i++) {
    var map = maps[i];
    var missingField = false;

    var grHardware = new GlideRecord('alm_hardware');
    grHardware.initialize();

    for (var field in map) {
        if (map[field] == '' || map[field] == null) {
            missingField = true;
            break;
        }
        grHardware.setValue(field, current.variables[map[field]]); //Not grComputer.setValue
    }
    if (missingField) {
        break; //if any field is missing, move onto next iteration
    }
    grHardware.install_status = '6';
    grHardware = 'available'; // not sure what this is doing
    grHardware.insert();
}

Thanks for the help!
And sorry about the part with Computer instead of Hardware, & line missing field on asset table.
They were typos not in original script.
