What is the best way of cloning/copying an observablearray in knockoutJS?

Question

Question says it all really. I want to copy an observable array to another in KnockoutJS.

Answer 1

I was faced with the same task; to clone an observable array. The only way I could figure out how to do it, is to convert the observable to an JS object, then convert that object to an observable object. The following function requires KnockoutJS mapping plugin: http://knockoutjs.com/documentation/plugins-mapping.html

function cloneObservable(observableObject) {
    return ko.mapping.fromJS(ko.toJS(observableObject));
}

Hope this helps
