如何实现定时器控制自身的定时时间？

Question

 var a = 100;
        var timer1 = setInterval(function() {
            a += 1000;
            console.log(a);
        }, a);

        var timer2 = setInterval(function() {
            console.log(a +';');
        }, 1000);

我想让定时器的时间间隔a变化，但是这样不行？

Answer 1

清除计时器再重启

var a = 100;
function timer1Func(){
  a += 1000;
                        clearInterval(timer1)
                        timer1 = setInterval(timer1Func, a);
            console.log(a);
}
        var timer1 = setInterval(timer1Func, a);
