Javascript mat选项卡中嵌套的组件是否有生命周期挂钩？

制表器新手

我有一个mat选项卡组，用于浏览三个制表器表

我使用的方法是在component.ts内创建一个div元素，并将其插入component.html内的现有div中

我遇到的问题是，只有选定选项卡的html加载到DOM中，因此未选定选项卡中的任何div元素都不在DOM中，并且不能通过id引用到我的component.ts中。当我切换到最初加载的选项卡以外的选项卡时，制表器表不会绘制

希望Angular有一个生命周期钩子，在mat选项卡的子组件上调用它，当用户选择该选项卡时，我可以使用它触发绘图

当然，我对其他/更好的方法持开放态度
