AngularJs - Determining the next location's route in $locationChangeStart
angular-routing, angularjs
Solution
I located the relevant source code lines in the AngularJS github project. Here is the function that it uses to match the URL to a route:
Since this functionality is not exposed by Angular I decided to come up with a rudimentary way of matching the URL to a route since the routes I was matching were relatively simple compared to implementing the same route matching that Angular does.
It ain't pretty, but it works..
Problem
Recently I found out about the undocumented $locationChangeStart event in AngularJS when trying to determine where in the framework I should be redirecting users to the login page if their session is invalid. I'm listening for the event using the following: ``` $scope.$on("$locationChangeStart", function (event, nextLocation, currentLocation) { // Logic goes here }); ``` where `nextLocation` and `previousLocation` are absolute urls to locations within the app. My question is this: Does AngularJS expose the ability to be able to match a url against a route, much like its internal routing engine does to see if an absolute URL matches a defined route? If not, what would be the best way to detect a route based on an absolute URL?
