Window Object Reference Window Object

Example

Display the current time (the setInterval() method will execute the function once every 1 second, just like a digital watch). Use clearInterval() to stop time:

var myVar = setInterval(function(){myTimer()}, 1000);

function myTimer() {
    var d = new Date();
    var t = d.toLocaleTimeString();
    document.getElementById("demo").innerHTML = t;
}

function myStopFunction() {
    clearInterval(myVar);
}

Definition and Usage

The clearInterval() method clears a timer set with the setInterval() method.

The ID value returned by setInterval() is used as the parameter for the clearInterval() method.

Note: To be able to use the clearInterval() method, you must use a global variable when creating the interval method:

myVar = setInterval("javascript function",milliseconds);

Then you will be able to stop the execution by calling the clearInterval() method.
