stop

Overview Table

This example uses the onstop event to stop a function from executing in a continuous cycle. The setInterval method is used to execute script every millisecond. If the user clicks the Stop button, the clearInterval method removes the interval and the script is no longer executed.

document.onstop=fnTrapStop;
window.onload=fnInit;
var oInterval;
function fnInit(){
   oInterval=window.setInterval("fnCycle()",1);
}
function fnCycle(){
   // Do something
}
function fnTrapStop(){
   window.clearInterval(oInterval);
}

Notes

Remarks

The onstop event fires after the beforeunload event, and before the unload event. Initiates any action associated with this event. To invoke this event, do one of the following:

• Click the Stop button.
