Changing the interval of SetInterval while it's running

Question

I have written a javascript function that uses setInterval to manipulate a string every tenth of a second for a certain number of iterations.

function timer(         


        

Answer 1

I had the same question as the original poster, did this as a solution. Not sure how efficient this is ....

interval = 5000; // initial condition
var run = setInterval(request , interval); // start setInterval as "run"

    function request() { 

        console.log(interval); // firebug or chrome log
        clearInterval(run); // stop the setInterval()

         // dynamically change the run interval
        if(interval>200 ){
          interval = interval*.8;
        }else{
          interval = interval*1.2;
        }

        run = setInterval(request, interval); // start the setInterval()

    }
