Reverse object in jQuery.each

Answer 1

I don't know, but for the simple stuff I work with, this function does the job. It doesn't rely on numeric keys. And will flip simple objects top to bottom. I don't understand complex Objects, so I don't know how "robust" it is.

function flipObject(obj){
    var arr = [];
    $.each(obj, function(key, val){
        var temp = new Object;
        temp['key'] = key;
        temp['val'] = val;
        arr.push(temp);
        delete temp;
        delete obj[key];
    });
    arr.reverse();
    $.each(arr, function(key, val){
        obj[val['key']] = val['val'];
    });
}
