// Simple example of using private variables // // To start the stopwatch: // obj.start(); // // To get the duration in milliseconds without pausing / resuming: // var x = obj.time(); // // To pause the stopwatch: // var x = obj.stop(); // Result is duration in milliseconds // // To resume a paused stopwatch // var x = obj.start(); // Result is duration in milliseconds // // To reset a paused stopwatch // obj.stop(); // var clsStopwatch = function() { // Private vars var startAt = 0; // Time of last start / resume. (0 if not running) var lapTime = 0; // Time on the clock when last stopped in milliseconds var now = function() { return (new Date()).getTime(); }; // Public methods // Start or resume this.start = function() { startAt = startAt ? startAt : now(); }; // Stop or pause this.stop = function() { // If running, update elapsed time otherwise keep it lapTime = startAt ? lapTime + now() - startAt : lapTime; startAt = 0; // Paused }; // Reset this.reset = function() { lapTime = startAt = 0; }; // Duration this.time = function() { return lapTime + (startAt ? now() - startAt : 0); }; }; var x = new clsStopwatch(); var $time; var clocktimer; function pad(num, size) { var s = "0000" + num; return s.substr(s.length - size); } function formatTime(time) { var h = m = s = ms = 0; var newTime = ''; h = Math.floor( time / (60 * 60 * 1000) ); time = time % (60 * 60 * 1000); m = Math.floor( time / (60 * 1000) ); time = time % (60 * 1000); s = Math.floor( time / 1000 ); ms = time % 1000; newTime = pad(h, 2) + ':' + pad(m, 2) + ':' + pad(s, 2) + ':' + pad(ms, 3); return newTime; } function show() { $time = document.getElementById('time'); update(); } function update() { $time.innerHTML = formatTime(x.time()); } function start() { clocktimer = setInterval("update()", 1); x.start(); } function stop() { x.stop(); clearInterval(clocktimer); } function reset() { stop(); x.reset(); update(); }
