按特定属性对可观察到的对象阵列进行排序的最有效方法是什么?

What is the most efficient way to sort a knockout observable array of objects by specific properties?

推荐答案

您的解决方案运行缓慢，并非归因于排序.这很慢，因为您将很多项目绑定到一页上.渲染200个项目要花费很多时间.此外，您的解决方案不是用户友好的.在没有分页和搜索的情况下使用大列表是非常不舒服的.

Your solution is slow not due to the sorting. It is slow because you bind a lot of items to one page. It takes much time to render 200 items. Moreover your solution is not user friendly. It is very uncomfortable to work with big list without pagination and searching.

所以我的建议是在列表中使用分页.在这种情况下，您将不会有任何性能问题.

So my advice is to use pagination in your list. In this case you will not have any performance issues.

这是一个简单的客户端分页示例: 客户端分页

Here is an example of simple client side pagination: Client-Side Pagination
