Window clearInterval() Method
Example
Display the current time (the setInterval() method will execute the "myTimer" function once every 1 second).
Use clearInterval() to stop the time:
var myVar = setInterval(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 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.
clearInterval(myVar);
