Adding Parameter to Angular router.navigate

Question

First of all, I am not sure if this is the right way, to achieve what I want.. I am trying to add an export binding like the following to a router.navigate()-method:

<call [caller]="caller"></call>

The problem is that I never use the directive, but instead adress it through a router:

acceptCall() {
   this.router.navigate(["call"]);
}

How can I achieve the same export binding from the first example in the acceptCall()-method? I Have already added an Input() variable and tried it with queryParams like this:

@Input() caller: Caller;
acceptCall(caller) {
    this.router.navigate(["call"], {queryParams: caller});
}

But this does not work.

Solution

Following my comments you have to :

1 - Redefine your route

{path: 'call/:caller', component: MyComponent }

2 - Change your navigation in the parent component

this.router.navigate(["call", caller]);

3 - In the child component, get the param

import { ActivatedRoute } from '@angular/router';
// code until ...
myParam: string;
constructor(private route: ActivatedRoute) {}
// code until ...
ngOnInit() {
    this.route.params.subscribe((params: Params) => this.myParam = params['caller']);
}

Almost ! try this.router.navigate(["call", caller]);

Doesnt work for me, Do I have to modify my RouterModule.forRoot? mine currently looks like: { path: 'call', component: CallComponent }

[Admin]

Well yes, {path: 'call/:caller'} and you can get it with this.route.params.subscribe((params: Params) => this.myParam = params['caller']); in your subcomponent (route is an ActivatedRoute)

I have updated my module, but dont quite get the other stuff :D Where do you declare Params , myParam? could you maybe provide a full code example of the class as an answer?

@reveN: it's not very obvious how your code is organized. It would be easier to help you if you said clearly where all the bits of code you provided are located.

In my app.module.ts I got my RouterModule with {path ....} In my parent.component I Import my Caller Object and want to inject it with the acceptCall-method to my child.component.ts, where I want to use the Caller object to get for example the phonenumber and the name of the caller

mhh Ive done everything exactly as you said, but my router roots now back to my "home"-component instead of the call-component, when I call the method

[Admin]

I used calls like this.router.navigate(['../user', id], { relativeTo: this.route }); to be sure that it would redirect to the right url. Could you try it ?

[reveN]

ive created a mock caller and get the following error: Error: Cannot match any routes. URL Segment: 'call;Id=1;Name=Frodo%20Baggins;Tel=12345%2F678910;Company=T‌​he%20Fellowship%20of‌​%20the%20Ring'

[reveN]

so I get all the caller information I want, but I want to use it inside the component, not the URL

[Admin]

Oh ! Then use either a service or a Parent-Child relation. route params aren't made for that.

[Admin]

Or maybe you can use the ActivatedRoute.data property, but I've never used it. Find more here

just for completeness, you also need to import Params from @angular/router

Coment with this.router.navigate(['../user', id], { relativeTo: this.route }); helped me (I used ActivatedRoute for router ). It will be good to be included in answer.
