Javascript Amazing Timer

Very usable and simple javascript object-oriented timer implementation. Displays real time passed and counting ticks. Simple JS API.

Demo:

Simple, Countdown, Stopwatch: https://rawgit.com/cloady/amazing.timer.js/master/example.html

Stopwatch with history: https://rawgit.com/cloady/amazing.timer.js/master/index.html

Examples:

• Using for store time

   var timer1 = new Timer();
   // some actions
   timer1.stop();
   console.log(timer1.total());

• Set interval analog

   var timer1 = new Timer(function() {
      console.log('seconds left:', this.tick());
      return true;
   }, 1000);
   
   // timer1.stop();

• Set timer 2 seconds

   var timer1 = new Timer(function() {
      console.log('fire in 2 seconds');
   }, 2000);

• Set timer end in 5 seconds tick with intervals of 500ms

   var timer1 = new Timer(function() {
      console.log('tick new 500ms, current timer is', this.time());
      return (this.time()<2000);
   }, 500);

• Set timer end in 10 ticks with intervals of 500ms

  var timer1 = new Timer(function() {
      console.log('tick new 500ms, tick number is', this.tick());
      return (this.tick()<10);
  });

• Custom timeout condition

  var ajaxLoaded = false;
  $.load('test.html', function(data) { ajaxLoaded = true });
  var timer1 = new Timer(function() {
      console.log('total time passed while loading page', this.total());
      return ajaxLoaded;
  }, 500);

• Timer countdown example

   var timer1 = new Timer(function() {  
      console.log('countdown', 20-this.tick()); 
      return (this.total() < 20000);  
   }, 1000);

• Timer uses as stopwatch

  var timer1 = new Timer(function() {
      console.log('tick number', this.tick(), ', time value', this.time());
      return true;
  });
  
  setTimeout(function() { timer1.fire(); 
       console.log('3 seconds timeout');
         setTimeout(function() { console.log('3 seconds passed'); 
             timer1.step(); 
             setTimeout(function() { timer1.fire(); }, 3051);
     }, 3000);
  }, 5051);

Methods:

• ready() -> true/false. Get ready state of timer.
• tick() -> integer. Get current iteration number.
• time() -> integer. Get iteration time in ms.
• total() -> integer. Get total timer run time in ms.
• fire() -> integer. Fire event before timer tick (you can sent time in ms as parameter).
• restart() -> integer. Starts new loop.
• loop() -> integer. Get current number of loop.
• step() -> integer. Starts new step/tick.
• stop() -> null. Stop the timer.
• start() -> null. Stop the timer.
• clear() -> null. Reset timer counters.
