This post assumes you have a working knowledge of Knockout JS.

Observable Array([ { name: "John Doe" }, { name: "Jane Doe" } ]); console.log(complex[0] instanceof Observable Object); // outputs "true" var primitive = new Observable Array([ "John Doe", "Jane Doe" ]); console.log(typeof (primitive[0]) ); // outputs "string" var array = new Observable Array([1, 2]); console.log(array.parent()); // outputs "undefined" var observable = kendo.observable({ numbers: [1, 2] }); var numbers = observable.get("numbers"); console.log(numbersperson.parent() === observable); // outputs "true" var array = new Observable Array([{ name: "John Doe" }]); var length = array.push({ name: "Jane Doe" }); console.log(length); // outputs "2" console.log(array[1] instanceof Observable Object); // outputs "true" console.log(array[1].get("name")); // outputs "Jane Doe" . If negative, will begin that many elements from the end. Observable Array(["football", "basketball", "volleyball"]); var removed = sports.splice(1, 1, "tennis", "hockey"); console.log(removed); // outputs ["basketball"] console.log(sports); // outputs ["football", "tennis", "hockey", "volleyball"] var people = new

An integer indicating the number of items to remove. In this case, you should specify at least one new item. Observable Array([ { name: "John Doe" }, { name: "Jane Doe" } ]); var json = JSON(); console.log(JSON.stringify(json)); // outputs [{"name":"John Doe"},{"name":"Jane Doe"}] var array = new

Observable Array([1, 2, 3]); array.bind("change", function(e) { console.log(e.action, e.index, e.items); }); array.push(4, 5); // outputs "add", 3, [4, 5] array.pop(); // outputs "remove", 4, [5] var people = new

Recently I had occasion to bind a list of checkbox input elements to a Knockout JS observable Array.

It actually took me a great deal of time to get the implementation working.

In this post I am going to cover the issues I experienced.

Then I will explain how implement a surefire checkbox-Knockout JS binding solution.
