Angular 2 - 应该是routerLink =“theRoute”还是[routerLink] =“['the route']”？

Question

I am really confused whether I should be using

<a routerLink="/about">About</a>

or

<a [routerLink]="['/about']">About</a>

Answer 1

Both are correct.

<a routerLink="/about">About</a>

and

<a [routerLink]="'/about'">About</a>

pass a path as string

while

<a [routerLink]="['/about']">About</a>

passes an array of router commands.

Both are supported.

  @Input() set routerLink(data: any[]|string) { 

Answer 2

Angular2 docs shows usage of :

<a [routerLink]="['/about']">About</a>

It also allows passing objects while routing

Check :- https://angular.io/docs/ts/latest/guide/router.html#!#link-parameters-array

Answer 3

You want your url to be passed as an object to the router, Pass it as

 <a [routerLink]="['/myPage']" title="My Page">MyPage</a>,

giving it like this

<a routerLink="/about">About</a

will pass it as a string so will throw error
