use jQuery’s find() on JSON object

by

jQuery doesn’t work on plain object literals. You can use the below function in a similar way to search all ‘id’s (or any other property), regardless of its depth in the object:

function getObjects(obj, key, val) {
    var objects = [];
    for (var i in obj) {
        if (!obj.hasOwnProperty(i)) continue;
        if (typeof obj[i] == 'object') {
            objects = objects.concat(getObjects(obj[i], key, val));
        } else if (i == key && obj[key] == val) {
            objects.push(obj);
        }
    }
    return objects;
}

Use like so:

getObjects(TestObj, 'id', 'A'); // Returns an array of matching objects
