JavaScript timer cancel timer and optimization method

JavaScript timer cancel timer and js timer optimization method

Common methods:

Start the timer:

(Method,Time) 

Method is a timed call js method

Time is the interval time, in milliseconds

Cancel the timer:

clearInterval(Method); 

Then the question is. Use clearInterval(timerid); to clear it, and it often cannot be stopped immediately. What method is easier to solve?

The optimization plan is as follows

var timeout = false; //Start and close buttonfunction time() 
{ 
 if(timeout) return; 
 Method(); 
 setTimeout(time,100); //time refers to itself, delayed recursive call itself, 100 is the interval call time, unit milliseconds} 

Summarize

Generally, setInterval is not used, but delay recursion of setTimeout is used instead of interval.

setInterval will generate callback stacking, especially when the time is short.
