How to use routerLinkActive with empty routerLink

问题

I have the following tab bar links and the first one is supposed to be empty:

<nav md-tab-nav-bar>
          <a md-tab-link [routerLink]="'./'" 
             routerLinkActive #rla="routerLinkActive" [active]="rla.isActive">
            My tab
          </a>
...
</nav>

The link works fine but the active state is not triggered.

What is the proper way to handle empty routerlink for the tab to be activated?

回答1:

Try this instead

<a [routerLink]=" ['./'] "
    routerLinkActive="active" [routerLinkActiveOptions]= "{exact: true}">
    My tab
</a>
