# Window clearInterval() Method

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);
}
Try it yourself »

## 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.

## Browser Support

The clearInterval() method is supported in all major browsers.

clearInterval(id_of_setinterval)
