推荐答案

您可以使用=Observable.empty()或=Observable.from([])将视图设置为空数组，但是如果要获取数据，则需要重新绑定服务.这就是为什么最简单的方法是只调用.next([])然后在需要时提取数据的原因.参见此示例

You can set the view to empty array using either =Observable.empty() or =Observable.from([]) but you will need to rebind the service back again if you want to fetch data. This is why the easiest way will be to just call .next([]) and then when needed fetch the data. See this example
