Instead of $routeChangeStart
use $locationChangeStart
Here’s the discussion about it from the angularjs guys: https://github.com/angular/angular.js/issues/2109
Edit 3/6/2018 You can find it in the docs: https://docs.angularjs.org/api/ng/service/$location#event-$locationChangeStart
Example:
$scope.$on('$locationChangeStart', function(event, next, current) {
if ($scope.form.$invalid) {
event.preventDefault();
}
});
