Automatically sort ko.observableArray as bound properties change
knockout.js
Solution
You can subscribe an observable and act whenever that observable changes:
person.age.subscribe(function (newValue) {
viewModel.someSortFunction();
});
Problem
is there a way to automatically sort an observable array when a bound property is changed? I believe in the following example, my view is updated when i add a new person, but can I get the view to refresh and apply my sorting function if one of the person's age is changed? ``` person = { age: ko.observable(); } viewModel = { people: ko.observableArray([]), someSortFunction: function() { this.people.sort(function(person1, person2) { return person2.age() - person1.age(); }); } } <div data-bind="foreach: people"> <span data-bind="text: age"/> </div> ```
