An SVG-based jQuery and Zepto circular timer plugin.

How to use

Fork this repository or download the circletimer.min.js and circle.css files from the dist directory of this project.

Options

  • timeout (number): the time that the timer should count for, in milleseconds. The default value is 5000
  • onComplete (function): the callback to be executed when the time has run out. The default value is an empty function
  • onUpdate (function): the callback to be executed each update of the timer. The default value is an empty function
  • clockwise (boolean): whether or not the timer should be going clockwise. If set to false, the timer moves counterclockwise. The default value is true

Example Code

  onComplete: function() {
    alert("Time is up!");
  },
  onUpdate: function(elapsed) {
    $("#time-elapsed").html(Math.round(elapsed));
  },
  timeout: 5000
});

$("#start").on("click", function() {
  $("#example-timer").circletimer("start");
});

  $("#example-timer").circletimer("pause");
});

$("#stop").on("click", function() {
