我按照例子 还有手头看过的代码 试着做了一下 上面代码使用了knockout.js 学习了一下 但是 就获取 gridstack 没有办法 获取
{ x，y，width，height}
在gitHub gridsack 作者哪里的 demo 还有 api 里面 看到 使用float.html 这个例子 加上下面事件，无knockout.js
$('.grid-stack').on('change', function(event, items) {
console.log('更改item added');
console.log(items);
}) 这个改变的事件， 这个是可以输出的 但是使用上面的 knockout.js 我尝试着 绑定事件 但是没有获取到 对应的值
我就是像做一下 这个窗口的大小后 通过change 事件 获取 当前改变的{x，y，width，height}
谢谢大佬们！O(∩_∩)O
