# 远程加载数据
|
|
|
|
- order: 7
|
|
|
|
在 `0.11.0` 以后,`dataSource` 远程模式被移除,用户可以自行实现数据读取方式。
|
|
|
|
这个例子通过简单的 ajax 读取方式,演示了如何从服务端读取并展现数据,具有筛选、排序等功能以及页面 loading 效果。开发者可以自行接入其他数据处理方式。
|
|
|
|
另外,本例也展示了筛选排序功能如何交给服务端实现,列不需要指定具体的 `onFilter` 和 `sorter` 函数,而是在把筛选和排序的参数发到服务端来处理。
|
|
|
|
**注意,此示例是静态数据模拟,展示数据不会变化,请打开网络面板查看请求。**
