Passive Link in Angular 2 - a href equivalent

Question

In Angular 1 x I can do the following to create a link which does basically nothing    lt a href    gt My Link lt  a gt    But the same tag navigates to the app base in Angular 2  What is the equivalent of that in Angular 2   Edit  It looks like a bug in the Angular 2 Router and now there is an open issue on github about that   I am looking for an out of the box solution or a confirmation that there won t be any

You have prevent the default browser behaviour. But you don’t need to create a directive to accomplish that.

It’s easy as the following example:

my.component.html

<a href="" (click)="goToPage(pageIndex, $event)">Link</a>

my.component.ts

goToPage(pageIndex, event) {
  event.preventDefault();
  console.log(pageIndex);
}

A really simple solution is not to use an A tag - use a span instead    lt span class  link   click   doSomething    gt Click here lt  span gt   span link     color  blue    cursor  pointer    text-decoration  underline

If you have Angular 5 or above  just change    lt a href     click   passTheSalt    gt Click me lt  a gt    into   lt a  routerLink      click   passTheSalt    gt Click me lt  a gt    A link will be displayed with a hand icon when hovering over it and clicking it won t trigger any route   Note  If you want to keep the query parameters  you should set queryParamsHandling option to preserve    lt a  routerLink        queryParamsHandling  preserve      click   passTheSalt    gt Click me lt  a gt

That will be same  it doesn t have anything related to angular2  It is simple html tag   Basically a anchor  tag will be rendered by HTML parser   Edit  You can disable that href by having javascript void 0  on it so nothing will happen on it   But its hack   I know Angular 1 provided this functionality out of the box which isn t seems correct to me now     lt a href  javascript void 0    gt Test lt  a gt    Plunkr    Other way around could be using  routerLink directive with passing    value which will eventually generate blank href      lt a routerLink     click   passTheSalt    gt Click me lt  a gt

There are ways of doing it with angular2  but I strongly disagree this is a bug  I m not familiarized with angular1  but this seems like a really wrong behavior even though as you claim is useful in some cases  but clearly this should not be the default behavior of any framework    Disagreements aside you can write a simple directive that grabs all your links and check for href s content and if the length of it it s 0 you execute preventDefault    here s a little example    Directive     selector     href      host           click      preventDefault  event          class MyInhertLink      Input   href    preventDefault event        if this href length    0  event preventDefault            You can make it to work across your application by adding this directive in PLATFORM DIRECTIVES  bootstrap App   provide PLATFORM DIRECTIVES   useValue  MyInhertLink  multi  true        Here s a plnkr with an example working

An achor should navigate to something  so I guess the behaviour is correct when it routes  If you need it to toggle something on the page it s more like a button  I use bootstrap so I can use this     lt button type  button  class  btn btn-link   click   doSomething    gt My Link lt  button gt

I wonder why no one is suggesting routerLink and routerLinkActive  Angular 7    lt a  routerLink       resources     routerLinkActive  currentUrl    resources   gt    I removed the href and now using this  When using href  it was going to the base url or reloading the same route again
