Question

I have the below JSON returned from a DB. How do I refer to the element STOCK without specifying by name? I know I can do NewDataSet.STOCK but this JSON is dynamic.

I have tried NewDataSet[1] but it doesn’t like that. Is there a way to refer to it?

{
    "NewDataSet": {
            "@": {
                "xmlns": "STOCK"
            },
            "STOCK": {
                "STOCK_GROUP": "Default",
                "STOCK_CODE": "qwertyuiop",
                "FEEDER_OR_TRAY_NUMBER": "1",
                "ENABLED": "Enabled",
                "WEIGHT": "1",
                "PRIORITY": "0",
                "STOCK_TYPE": "Paper",
                "STOCK_ID": "1",
                "VALID_FROM": "1900-01-01T00:00:00+00:00",
                "VALID_TO": "1900-01-01T00:00:00+00:00",
                "STOCK_IMAGE": {}
            }
        }
    }

Here is an example of 2 or more rows::

{
    "NewDataSet": {
        "@": {
            "xmlns": "SECURITY_GROUPS"
        },
        "SECURITY_GROUPS": [
            {
                "GROUP_ID": "100",
                "NAME": "Administrators",
                "DESCRIPTION": "Access to all aspects of system"
            },
            {
                "GROUP_ID": "101",
                "NAME": "Operators",
                "DESCRIPTION": "users of device"
            }
        ]
    }
}

I then run this javascript:

$.each(data[0], function(key, value) {
    columnArr.push({"sTitle" : key});
});

$.each(data, function(key, value) {
    var innerArr = [];
    $.each(value, function(innerKey, innerValue) {
        innerArr.push(innerValue);
    });
    alueArr.push(innerArr);
});

You can iterate over the elements in a associative array like this:

for (var key in NewDataSet) {
    if (obj.hasOwnProperty(key)) {
        // key holds 'STOCK', obj[key] holds the data you are after
    }
}

Looking at the data, they kind of suggest what you should actually do is to explicitly retrieve ‘@’ and then check ‘xmlns’ in there to understand what key you should be searching for…

— edit after your edits it’s clearer that this is what you need

var tableName = NewDataSet['@'].xmlns;
var rows = NewDataSet[tableName];
// enforce array
if (!rows.hasOwnProperty('length')) { rows = [rows]; }
