The hash is the part of the url that goes after the # symbol. That was initially intended to direct you (locally) to sections of your HTML document, but … Read more

Redirect using AngularJS

January 27, 2023 by Tarik

With an example of the not-working code, it will be easy to answer this question, but with this information the best that I can think is that you are calling the $location.path outside of the AngularJS digest. Try doing this on the directive scope.$apply(function() { $location.path(“/route”); });

Assuming that errors are normally distributed (which, as the docs say, is not necessarily true), that means that this … Read more
