Utility class to simplify use of timers created by setTimeout.
- Support for one-time (like
setTimeout) or recurrent (likesetInterval) timers. - It is possible to repeat action indefinitely (
recurrentproperty), specified number of times (repeatQtyproperty) or depending on result of control function (repeatTestproperty). - Time period (timeout) can be: a fixed value, a random value, an item selected from a list depending on action's execution number, or a value returned from specified function.
- Action that is called can be a function or an object specifying function and its call's context.
- Action result is saved in timer's field for further access.
- Timer's start time, stop time and action execution times are saved in
startTime,stopTimeandexecuteTimeproperties correspondingly.
var timer = new Timer({
period: [100, 200, 300, 400, 500, {start: 100, end: 500}],
repeatQty: 100,
passToAction: true,
action: function(tmr) {
console.log("#", tmr.getExecutionQty() + 1, ":", new Date());
},
active: true
});
...
timer.stop();npm install chronoman
bower install chronoman
Use dist/chronoman.js or dist/chronoman.min.js (minified version).
import Timer from "chronoman";var Timer = require("chronoman").Timer;define(["path/to/dist/chronoman.js"], function(chronoman) {
var Timer = chronoman.Timer;

});<!-- Use bower_components/chronoman/dist/chronoman.js if the library was installed by Bower -->
<script type="text/javascript" src="path/to/dist/chronoman.js"></script>
<script type="text/javascript">
// сhronoman is available via Chronoman field of window object
var Timer = Chronoman.Timer;

}
});
var tmrTwo = new Timer();
tmrTwo.setPeriod([2000, {start: 1000, end: 1500}])
.setRepeatQty(9)
.setPassToAction(true)
.setAction({
i: 0,
execute: function(timer) {
var nI = ++this.i;
console.log("Timer two. #", nI, timer);
tmrOne.setActive(nI % 2 === 1);
}
});
var tmrThree = new Timer()
.setPeriod(3000)
.setRepeatTest(function() {
return tmrTwo.isActive();
});
tmrThree.onExecute = function() {
console.log("* Timer three. #", this.getExecutionQty() + 1);
};
tmrTwo.start();See test/chronoman.js for additional examples.

This module is inspired by qooxdoo's qx.event.Timer class.
