我真的是新的knockout.js.我想要实现的是限制foreach项目.这是我的来源:

<div data-bind="foreach: news">

            <div  class="news-item">
                <a data-bind="attr: { href: url, title: title }">

                {
                    window.parent.handleChildIframeUrlChange(location.hash)
                });
            }

            // Class to represent a row in the seat reservations grid
            function cebesEnNewsIndex(title, date, url, catId, hits)
            {
                var self = this;
                self.title …
