浅谈angular4.0中路由传递参数、获取参数最nice的写法

const routes: Routes = [
{
 path: 'product',
 component: ProductComponent,
 },
 {
 path: 'product-detail',
 component: ProductDetailComponent,
 }
];

constructor(
 private router: Router, //这里需要注入Router模块
){}
jumpHandle(){
 //这是在html中绑定的click跳转事件
 this.router.navigate(['product-detail'], {
 queryParams: {
  productId: '1',
  title: 'moon'
 }
 });
}

constructor( 
 private activatedRoute: ActivatedRoute, //这里需要注入ActivatedRoute模块 
) { 
 activatedRoute.queryParams.subscribe(queryParams => { 
 let productId = queryParams.productId; 
 let title = queryParams.title; 
 }); 
}
