{{APIRef("HTML DOM")}}

The clearInterval() method of the {{domxref("Window")}} interface cancels a timed, repeating action which was previously established by a call to {{domxref("Window.setInterval", "setInterval()")}}. If the parameter provided does not identify a previously established action, this method does nothing.

Syntax

clearInterval(intervalID)

Parameters

• intervalID
  • : The identifier of the repeated action you want to cancel. This ID was returned by the corresponding call to setInterval().

It's worth noting that the pool of IDs used by {{domxref("Window.setInterval", "setInterval()")}} and {{domxref("Window.setTimeout", "setTimeout()")}} are shared, which means you can technically use clearInterval() and {{domxref("Window.clearTimeout", "clearTimeout()")}} interchangeably. However, for clarity, you should avoid doing so.

Return value

None ({{jsxref("undefined")}}).

Examples

See {{domxref("Window.setInterval", "setInterval()")}} for examples.
