angular append component to respective tabs

问题

I am trying to append component (dynamic created) to respective tabs using angular material and @viewChild but it is going to first tab only when I click button in the 2nd tab.

Here is Stackblitz - angular-append-component-to-respective-tabs

It's not displaying in individual tab. I have 3 tabs. all 3 tabs contains Add button, when I click on 1st tab's button, it's adding that component in 1st tab but when I click on 2nd tab's Add button, it's adding that component in 1st tab only, it should add in 2nd tab.

Can someone please help me to figure-out how to do this?

Have a working example here https://stackblitz.com/edit/angular-append-component-to-respective-tabs-jp5zzt-p7nonq

With ViewChild you always access the first one. Use ViewChildren and access with the selectedIndex

回答2:

You can use ViewChildren instead of ViewChild.
@ViewChildren('appenHere', {read : ViewContainerRef}) tabList: QueryList<ViewContainerRef>;
so you can use it like this:
this.componentRef = this.tabList.toArray()[1].createComponent(childComponent);
You can also pass index as parameter to addNewComponent function.

回答3:

The target property of your implementation always points to the div inside the first tab. Which is why the component is always created there.

You can get around this using ViewChildren to access the divs from all the tabs. And when the user clicks on the Append button, simply pass the tab index to the event handler function and create the component inside the correct tab.
