在Javascript对象中查找特定值

Question

I humbly ask for assistance. I am working on a project where I need to set up a search to find all instances, inside an Object where a particular value equals whatever term the user is searching for. I found the following code:

    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;
}

here (to make sure proper credit is given),which works great, but I am looking for some help on expanding the functionality of this code to include the ability to search for more than one element at a time, and also, on the return, display other values in the same objects being returned. As an example, the returns, using the above code, are simply [Object]:

What I was hoping to do was to append the [>Object] with another variable value from the Object, perhaps the ID or Description, both of which are part of the returned results. So, the desired results would be something like "Object: ID=b01" or "Object: Desc = This is Maple", something that will allow my users to quickly see which one of the results they need to look at.

Thank you in advance for your assistance!

From your description, I have changed the function to look through a tree like object and be able to pick out the objects that contain all of the supplied key-value pairs. In addition, it allows you to specify that you want to output extra parameters on the objects that match. (like the id and description )

Here is the code and example http://jsfiddle.net/hjhQz/
