AngularJS - Update model based on URL
angularjs, javascript
Solution
$scope.$watch(function() {
return $location.path();
}, function(){
...
});
you should pass a function or a string that can be evaluated inside of the scope
Problem
This is basically a follow up question this question: AngularJS - How to use $routeParams in generating the templateUrl?. See my code there for the proper context of this question. All the navigation part is working great, but now when I navigate, I want to update some properties in my `$scope` based on the `primaryNav` and `secondaryNav`. I thought I could do something with `$watch` but I can't seem to get anything to work. Here are a few things I tried: ``` $scope.$watch($location.path(), function() {...}); //result in js error $scope.$watch($location, function() {...}); //function runs once on page load, but not after that $scope.$watch($window.location, function() {...}); //function runs once on page load, but not after that $scope.$watch(window.location, function() {...}); //function runs once on page load, but not after that $scope.$watch(window.location.href, function() {...}); //results in js error ``` I could probably create some method in my controller that would take these navs and update everything and navigate off and just add a `ng-click` to all the anchor tags. However, one thing I really liked about AngularJS was being to use real URL-looking values for hrefs (e.g. `<a href="#/priNav/secNav">Foo</a>`). Is it not possible to update my model based on the changing URL when I route without going through some method on the controller? I hope it makes sense what I'm asking.
