KnockoutJS binding that enables handling enter key presses and performing an action

ko.bindings.executeOnEnter.js

ko.bindingHandlers.executeOnEnter = {
    init: function (element, valueAccessor, allBindingsAccessor, viewModel) {
        var allBindings = allBindingsAccessor();
        $(element).keypress(function (event) {
            var keyCode = (event.which ? event.which : event.keyCode);
            if (keyCode === 13) {
                ko.utils.triggerEvent(element, 'change');

                allBindings.executeOnEnter.call(viewModel, viewModel, event);
                return false;
            }
            return true;
        });
    }
};
