错误类型错误：无法读取未定义角度的属性“选项卡”

Question

MemberDetailedComponent

@ViewChild('memberTabs', { static: false }) memberTabs: TabsetComponent;
ngOnInit() {
    /* get thr routes tab parameter */
    this.route.queryParams.subscribe(params => {
      // tslint:disable-next-line: no-string-literal
      const selectTab = +params['tab'];
      console.log('queryparams:' + selectTab);
      this.memberTabs.tabs[selectTab > 0 ? selectTab : 0].active = true;
    });
}

selectTab(tabId: number) {
    this.memberTabs.tabs[tabId].active = true;
  }

在路由器链接中

[routerLink]="['/members']"[queryParams]="{ tab: 3 }"

虽然 selectTab 读取了值，但控制台显示标签未定义

Answer 1

将{ static: false} 替换为{ static: true }。
