How to check if location.hash has `#access_token=` and if so, do something?

Question

Right now, I'm just doing the following for my Auth0 login -

if (location.hash) {
  // do something
}

How can I make sure it will only do this when it includes #access_token= ?

Answer 1

Use indexOf like so.

if(location.hash.indexOf("#access_token=" > -1) {
       // Do stuff
}
