Answer 1

The problem is that you probably inject $routeParams or $route in a controller that is run before a route change has occurred, e.g. your main/master/page controller.

If you inject $routeParams in a controller for a specific route (specified by the controller property when you define the route), then it will work, otherwise you're probably better of listening to the various events the route service broadcasts.

Try to change your code to use

$scope.$on('$routeChangeSuccess', function (ev, current, prev) {
   // ... 
});

Requirements: Ensure 'ngRoute' is in your app module

Route provider set up as: http://localhost/var/:valName

Function set up as:

function functionName($scope, $routeParams){$scope.value = $routeParams.valName;}

HTML view:

{{value['valName']}}
