当我在

app.component.html

页面中单击一个产品链接时，它会加载包含该产品信息的

ProductDetailsComponent

，但当我再次尝试单击其他链接时，浏览器中的URL会改变，但什么也不会发生

我需要的是，在第一个页面加载时，比如“local.shop.com”，会在

app.component.html

中显示一个包含产品链接的静态组件，当您单击每个链接时，它会显示有关该产品的信息。我尽量避免重新加载页面

我不确定还需要哪些代码片段来为这个问题提供足够的上下文，但请让我知道。

这是因为角度组件重用功能改变了url，但没有改变视图。您需要订阅ProductDetailsComponent中接收到的参数，并对其执行一些操作

1） 在ProductDetails组件中，从@angular/route导入ActivatedRoute并从rxjs导入订阅

import { Subscription } from 'rxjs/Rx';
import { ActivatedRoute} from '@angular/router';
import { Component, OnInit, OnDestroy} from '@angular/router';

export class ProductDetailsComponent implements onInit, onDestroy {
private subscription: Subscription;
productId: string;

2） 在你的ngOnInit中，订阅并在其中做一些事情

  ngOnInit() {
      this.subscription = this.activatedRoute.params.subscribe((params) => {
      this.productId = params['id'];
     //do something here to trigger the changes
      this.product = this.productService.getProduct(this.productId); 
     //example
     console.log(this.product);
}); 

3） 最后但并非最不重要的一点，不要忘记取消订阅

    ngOnDestroy() {
    this.subscription.unsubscribe();
    }

当然，不要忘记在构造函数中调用它

 constructor(private activatedRoute: ActivatedRoute) {}

如何在ProductDetailsComponent中输入产品id。您应该订阅参数，以便您的组件可以检测url参数何时更改您如何在ProductDetailsComponent中提取产品id。你应该订阅这些参数，这样你的组件就可以检测url参数什么时候改变了，我在上面停留了这么长时间。非常感谢。我已经在这上面呆了很久了。非常感谢。
