Angular2 onclick在ngfor中

Question

Trying to output a function call with click during ngFor. I'm not sure how to reference it.

I'm new to angualr2, and I'm not sure if this is the correct way to achieve this. I would appreciate any advise.

export class Navbar {

    constructor() {}

    public userNavs = [
        { title: 'Account', click: 'account()'  },
        { title: 'Logout', click: 'logout()'  }
    ]

    logout() {
        console.log('working');
    }

    account(){
        console.log('working');
    }

    ngOnInit() {}
}

////HTML////

<ul class="dropdown-menu dropdown-menu-right" aria-labelledby="userdropdown">               
    <li *ngFor="let nav of userNavs" ><a class="dropdown-item btn-sm" (click)="{{ nav.click }}" >{{ nav.title }}</a></li>
</ul>

Answer 1

that is a better way:

    export class Navbar {

    constructor() {}

    public userNavs = [
        { title: 'Account', click: 'account()'  },
        { title: 'Logout', click: 'logout()'  }
    ]

    eventClick(userNav){
      if('Account') this.account();
      else this.logout();
    }

    logout() {
        console.log('working logout');
    }

    account(){
        console.log('working account');
    }

    ngOnInit() {}
}

<ul class="dropdown-menu dropdown-menu-right" aria-labelledby="userdropdown">               
    <li *ngFor="let nav of userNavs" ><a class="dropdown-item btn-sm" (click)="eventClick(nav)" >{{ nav.title }}</a></li>
</ul>
