The clearTimeout() method clears a timer set with the setTimeout() method.
The ID value returned by setTimeout() is used as the parameter for the clearTimeout() method.
myVar = setTimeout("javascript function",milliseconds);
Then, if the function has not already been executed, you will be able to stop the execution by calling the clearTimeout() method.
Syntax and Usage
clearTimeout(id_of_settimeout)
Parameter Values
Parameter Description id_of_settimeout Required. The ID value of the timer returned by the setTimeout() method
