Angular2素数数据表所选行使用路由器传递给其他组件

我有一个素数数据表，我想通过路由器将选定的行传递给其他页面。例如：我有一个学生数据表，当我选择一个学生行并单击提交按钮时，它应该在StudentDetails页面中显示详细信息

在这里，我可以选择行并将数据传递给student组件。但无法将数据传递给学生详细信息组件

export class Student {

selectedRow:Student;// I can able to assign selected row here

navigateStudentDetail(){

this.router.navigate(['./studentdetail']);

}

我可以使用query参数传递studentId，但我想将我的student对象传递给studentdetails组件。但是做不到

有什么简单的方法可以做到这一点吗？请帮助我

使用一个服务只是将一些参数传递给另一个组件可能有些过分。您可以使用NavigationExtras添加自定义数据以及要导航到的Url

import { NavigationExtras} from '@angular/router';
//You will need navigations extras from Router.

在组件中的某个地方

      let dataNav:NavigationExtras={queryParams:"somekey":"someValue",
"someOtherKey":"someOtherValue"}};
  this.router.navigate(['/path/whatever/'],dataNav);

import { Router, ActivatedRoute, Params } from '@angular/router';
//you will need something like this

  ngOnInit() {
this.route.queryParams
.subscribe(params =>{
  this.someOtherKeyReceived=params['someOtherKey']
});

然后在目标组件中

      let dataNav:NavigationExtras={queryParams:"somekey":"someValue",
"someOtherKey":"someOtherValue"}};
  this.router.navigate(['/path/whatever/'],dataNav);

import { Router, ActivatedRoute, Params } from '@angular/router';
//you will need something like this

  ngOnInit() {
this.route.queryParams
.subscribe(params =>{
  this.someOtherKeyReceived=params['someOtherKey']
});

在构造函数中实例化ActivatedRoute，如下所示

constructor(
private route: ActivatedRoute,
private router: Router){}

最后获取第一个组件发送的参数

      let dataNav:NavigationExtras={queryParams:"somekey":"someValue",
"someOtherKey":"someOtherValue"}};
  this.router.navigate(['/path/whatever/'],dataNav);

import { Router, ActivatedRoute, Params } from '@angular/router';
//you will need something like this

  ngOnInit() {
this.route.queryParams
.subscribe(params =>{
  this.someOtherKeyReceived=params['someOtherKey']
});
