How to explicitly define the global callback function for Implicit Grant?

[licaomeng]

I am using Implicit Grant to obtain access_token. I found that the global callback function cannot be triggered while redirected to the redirect_uri. How to trigger the callback function or explicitly define the callback function name?

window.oauth2Callback = function (uri) {
  ...
  ...
}
