Use the service $interval.

It is equivalent to API window.setInterval, but dedicated to using Angularjs (remember that Angular needs to update the view when the model is changed).

The use of this service is quite simple:

interval = $interval(fn, 1000, 0, true);

Description of parameters:

  1. Command to be executed when in range;
  2. Interval in ms of the shots;
  3. Number of repetitions. Use 0 to infinity (default);
  4. If Angular should call the service $apply when the shot is finished (default).

In the first parameter fn, you should call the Web Service, probably using the service $http.

  • I can pass the function that does this in this parameter fn?

  • Yes. Just be careful that if it needs some parameter, you will have to create a wrapper without parameters, or modify the function so that it no longer needs the parameter.
