什么时候加载所有组件? [英] When are all my components loaded?

问题描述

我有一个组件，它有几个孩子，他们可能也有一些孩子.我无法预测是否将加载所有子项，因为这取决于您所查看的内容.我要实现的是一个加载指示器，该指示器在加载内容时显示.但是我不想为每个组件显示一个加载指示器，因为我最终将拥有10-15个加载指示器.

I'm having a component, which has several children and they might also have some children. I can not predict, if all the children will be loaded, since it depends on the content your looking at. What I want to achieve, is a loading indicator which show while the content is loaded. But I don't want to display a loading indicator for every component, because I'll end up having 10-15 loading indicators.

我的想法是，根父级显示一个加载指示符，一旦所有子级都初始化，加载指示符就可以消失.但是，如何确保所有子代都已装载?

My idea is that the root parent, displays a loading indicator and once all the children are initialised the loading indicator can disappear. But how can I make sure that all the children are loaded?
