angular - 如何在 PrimeNG tabMenu 中设置活动选项卡？

Question

我在哪里声明 activeIndex 以及如何使用这个变量？

我有 html 文件：

<p-tabMenu [model]="tabMenuItems"></p-tabMenu>

和打字稿文件：

tabMenuItems: MenuItem[];
private stateId: number;
private id: number;
...
ngOnInit() {
   this.tabMenuItems = [
        {label: 'Bar1', icon: 'ui-icon-insert-chart',
            command: (event: any) => {
                this.router.navigate(['/#', 
             this.id],{ queryParams: {'stateId': this.stateId} }); }
        },
        {label: 'Bar2', icon: 'ui-icon-date-range',
            command: (event: any) => {
                this.router.navigate(['/#', this.id],{ queryParams: {'stateId': this.stateId} }); }
        },
        {label: 'Bar3', icon: 'ui-icon-book',
            command: (event: any) => {
                this.router.navigate(['/#', this.id],
                    { queryParams: {'stateId': this.stateId} }); }
        },
        {label: 'Bar4', icon: 'ui-icon-help-outline',
            command: (event: any) => {
                this.router.navigate(['/#', this.id],
                    { queryParams: {'stateId': this.stateId} }); }
        },
        {label: 'Bar5', icon: 'ui-icon-public',
            command: (event: any) => {
                this.router.navigate(['/#', this.id],
                    { queryParams: {'stateId': this.stateId} }); }
        }
    ];

如何设置活动选项卡，以便每个菜单项激活相应的选项卡？

文档

在 上设置[activeItem]属性tabMenu。

例子

ngOnInit() {
   this.tabMenuItems = [
        {label: 'Bar1', icon: 'ui-icon-insert-chart',
            command: (event: any) => {
                this.router.navigate(['/#', 
             this.id],{ queryParams: {'stateId': this.stateId} }); }
        },
        {label: 'Bar2', icon: 'ui-icon-date-range',
            command: (event: any) => {
                this.router.navigate(['/#', this.id],{ queryParams: {'stateId': this.stateId} }); }
        },
        {label: 'Bar3', icon: 'ui-icon-book',
            command: (event: any) => {
                this.router.navigate(['/#', this.id],
                    { queryParams: {'stateId': this.stateId} }); }
        },
        {label: 'Bar4', icon: 'ui-icon-help-outline',
            command: (event: any) => {
                this.router.navigate(['/#', this.id],
                    { queryParams: {'stateId': this.stateId} }); }
        },
        {label: 'Bar5', icon: 'ui-icon-public',
            command: (event: any) => {
                this.router.navigate(['/#', this.id],
                    { queryParams: {'stateId': this.stateId} }); }
        }
    ];

    this.activeTab = this.tabMenuItems[1];
}

在 HTML 中

<p-tabMenu [model]="tabMenuItems" [activeItem]='activeTab'></p-tabMenu>
