Transition provider targeting multiple states

There is to ways to target multiple states for a transition handler. *
Wildcard or Arrays.
By using *
one can target all states the the Hierarchy below.
So if we just use *
we target all existing states under root
, and we can define a global handler that gets called on all transitions by using *
both as destination and source.
angular.module('demo', ['ui.routing']).
config(['$stateTransitionProvider', function($stateTransitionProvider) {
$stateTransitionProvider
.transition('*', '*', function($transition) {
console.log('This handler will get called for all transitions');
})
}]);
We can also target all transitions to or from a specific state that way:
angular.module('demo', ['ui.routing']).
config(['$stateTransitionProvider', function($stateTransitionProvider) {
$stateTransitionProvider
.transition('*', 'state', function($transition) {
console.log('This handler will get called for all'
+ ' transitions to "state"');
})
.transition('state', '*', function($transition) {
console.log('This handler will get called for all'
+ ' transitions from "state"');
})
}]);
This was global handlers, but we might also wan't to target any state below a specific state:
angular.module('demo', ['ui.routing']).
config(['$stateTransitionProvider', function($stateTransitionProvider) {
$stateTransitionProvider
.transition('*', 'state.*', function($transition) {
console.log('This handler will get called for all transitions to'
+ ' "state" or any of its descendant states');
})
.transition('state.*', '*', function($transition) {
console.log('This handler will get called for all transitions from'
+ ' "state" or any of it's descendant states');
})
}]);
In addition to using the ´*´ wildcart to target multiple states, it is also possible to use arrays for a more specific match.
angular.module('demo', ['ui.routing']).
config(['$stateTransitionProvider', function($stateTransitionProvider) {
$stateTransitionProvider
.transition(['book', 'book.item', 'book.list'], 'paper',
function($transition) {
console.log('This handler will get called for transitions from'
+ ' "book", "book.item" and "book.list" to "paper"');
})
.transition('paper', ['book', 'book.item', 'book.list'],
function($transition) {
console.log('This handler will get called for transitions to'
+ ' "book", "book.item" and "book.list" from "paper"');
})
}]);
Since this really just iterates through the list and register the handler for each of the states, wildcards can also be used:
angular.module('demo', ['ui.routing']).
config(['$stateTransitionProvider', function($stateTransitionProvider) {
$stateTransitionProvider
.transition(['book', 'book.item.*', 'book.list.*'],
['paper', 'pen.*'], function($transition) {
console.log('Handle all the above, this creates'
+ ' to many combinations to write out');
})
}]);
