Start the timer:
Method is the js method that is called periodically
Time is the interval in milliseconds
Cancel the timer:
So here's the problem. Use clearInterval (timerid); To clear, often cannot stop immediately, with what method better solve?
The optimization scheme is as follows
var timeout = false; // Start and close buttons
setTimeout(time,100); //time Refers to itself , Delay recursively calls itself ,100 Is the interval call time , Unit of milliseconds
setInterval is generally not used, but setTimeout's delayed recursion instead of interval.
setInterval can cause callback accumulation, especially if the time is very short.
