How would I have ui-router go to an external link,

Question

For example:

 $stateProvider
            .state('external', {
                url: 'http://www.google.com',

            })

url assumes that this is an internal state. I want it to be like href or something to that effect.

I have a navigation structure that will build from the ui-routes and I have a need for a link to go to an external link. Not necessarily just google, that's only an example.

Not looking for it in a link or as $state.href('http://www.google.com'). Need it declaratively in the routes config.

Answer 1

I transformed the accepted answer into one that assumes the latest version of AngularJS (currently 1.6), ui-router 1.x, Webpack 2 with Babel transpilation and the ng-annotate plugin for Babel.

.run(($transitions, $window) => {
  'ngInject'
  $transitions.onStart({
    to: (state) => state.external === true && state.url
  }, ($transition) => {
    const to = $transition.to()
    $window.open(to.url, to.target || '_self')
    return false
  })
})

And here's how the state may be configured:

.config(($stateProvider) => {
  'ngInject'
  $stateProvider
    .state({
      name: 'there',
      url:'https://google.com',
      external: true,
      target: '_blank'
    })
})

Usage:

<a ui-sref="there">To Google</a>

Answer 2

As mentioned in angular.js link behaviour - disable deep linking for specific URLs you need just to use

<a href="newlink" target="_self">link to external</a>

this will disable angularJS routing on a specific desired link.

Answer 3

You could use the onEnter callback:

 $stateProvider
    .state('external', {
        onEnter: function($window) {
            $window.open('http://www.google.com', '_self');
        }
    });

Edit

Building on pankajparkar's answer, as I said I think you should avoid overriding an existing param name. ui-router put a great deal of effort to distinguish between states and url, so using both url and externalUrl could make sense...

So, I would implement an externalUrl param like so:

myApp.run(function($rootScope, $window) {
    $rootScope.$on(
        '$stateChangeStart',
        function(event, toState, toParams, fromState, fromParams) {
            if (toState.externalUrl) {
                event.preventDefault();
                $window.open(toState.externalUrl, '_self');
            }
        }
    );
});

And use it like so, with or without internal url:

$stateProvider.state('external', {
    // option url for sref
    // url: '/to-google',
    externalUrl: 'http://www.google.com'
});

Answer 4

Angular-ui-router doesn't support external URL, you need redirect the user using either $location.url() or $window.open()

I would suggest you to use $window.open('http://www.google.com', '_self') which will open URL on the same page.

Update

You can also customize ui-router by adding parameter external, it can be true/false.

  $stateProvider
  .state('external', {
       url: 'http://www.google.com',
       external: true
  })

Then configure $stateChangeStart in your state & handle redirection part there.

Run Block

myapp.run(function($rootScope, $window) {
  $rootScope.$on('$stateChangeStart',
    function(event, toState, toParams, fromState, fromParams) {
      if (toState.external) {
        event.preventDefault();
        $window.open(toState.url, '_self');
      }
    });
})

Sample Plunkr

Note: Open Plunkr in a new window in order to make it working, because google doesn't get open in iFrame due to some security reason.
