javascript - 更改 var speed 值 onClick？

Question

当用户单击按钮时，它将更改 var speed 值。我怎样才能做到这一点？目前，其设置为 1000 毫秒//1 秒，如下行所示:

var increment = setInterval(increment,1000); // gain 1 ever second // THIS IS WHAT I WANT TO CHANGE

我想将按钮的 1000 次点击更改为 2000 次。我想这就是所谓的增量值吧？我只知道它是我设置的在 1000ms 时间内获得数字的速度。

Answer 1

您可以清除间隔并重新创建

$('#element').click(function(){
     window.clearInterval(incrementID); //
     timing = timing + 1000; //this is if you plan to keep adding up.
     incrementID = setInterval(increment, timing);// if not you can always hardcode 2000
});

还有:

var timing = 1000;
var incrementID = setInterval(increment,timing); // gain 1 ever second // THIS IS WHAT I WANT TO CHANGE
//you should change the varname so that you can use the handle to clear the already set interval
