Do you know a way in ui-router to get the list of child states of a given state?
I'm implementing a complex SPA with maybe 4 level deep navigation using ui-router.
I would like to implement a navigation tab interface for the second level generated automatically from the router table.
For that, I need to get the list of direct children of a given state (maybe is an abstract state). The only way that I've found to get the states is to do a $state.get() and obtain the full list of states, but that means that I'll have to parse child states on my own, and I think that's code already written in ui-router.
I let this question here in case there's anyone with experience in the source code or know of a plugin or module that can help me on this. Meanwhile I will do a research on my own and post results if I find something.
In the end, had to implement the functionality myself.
In the controller of the abstract route that has the tab interface, filtered the states using a regular expression taking advantage of the default naming convention for routes:
var routeName='Root.Parent'; // this is the "actual" route
// this regex is going to filter only direct childs of this route.
var secondRouteOnlyRegex = new RegExp(routeName + "\.[a-z]+$", "i");
var states = $state.get();
// this uses lodash to filter the states based on the regex
var navLinks = _.filter(states, (s) => {
return secondRouteOnlyRegex.test(s.name) && !s.abstract;
});
$scope.tabs = navlinks;
My route definitions have a data property that contains the title and other metadata needed to render the tabs.
My template looks something like this (using bootstrap):
<ul class="nav nav-tabs">
<li ng-repeat="state in tabs" ui-sref-active="active">
<a href="{{state.url}}" ui-sref="{{state.name}}">{{state.data.title}}</a>
</li>
</ul>
