How do I make a deep copy of a knockout object that was created by the mapping plugin

Question

Here\'s my scenario. I\'m using the knockout mapping plugin to create an observable viewmodel hierarchy for me. My hierarchy has nested elements in it. At a particular point

Answer 1

ko.utils.clone = function (obj) {
    var target = new obj.constructor();
    for (var prop in obj) {
        var propVal = obj[prop];
        if (ko.isObservable(propVal)) {
            var val = propVal();
            if ($.type(val) == 'object') {
                target[prop] = ko.utils.clone(val);
                continue;
            }
            target[prop](val);
        }
    }
    return target;
};

Here is my solution, hope it helps. In this code, obj would be your viewModel object.
