ng-progressive-interval

Angular interval service which doubles the delay with every iteration

Installation

bower install ng-progressive-interval --save

Example

You can use it similarly like angular's built-in $interval service. Inject it as dependency and pass a function to it.

angular.module("myApp", ["retoheusser.ng-progressive-interval"])
.controller("myAppCtrl", function (progressiveInterval) {
  progressiveInterval(function () {
    // this gets executed after 1s, then after 2s, then 4s, then 8s and so on...
  }, 1000);
});

API

var cancelInterval = progressiveInterval(fn, initialDelay, maxDelay, maxIterations)

• Parameters:
  • fn: Function to execute
  • initialDelay: Delay in ms, increases by factor 2 in every iteration
  • maxDelay: If initialDelay exceeds maxDelay, use this value instead. It remains constant.
  • maxIterations: fn will not be executed more than this value. Inifite iterations if undefined or 0.
• Returns:
  • function: a callable function without parameters to cancel the interval.
