所以我有一个可以工作的旋转木马 - 在我的jsfiddle上看到它,https://jsfiddle.net/L4q2e35g/3/

我需要做的是自动启动和滑动而不是onclick功能,任何人都有一个快速的代码解决方案,使其工作?

在s

之后添加一个功能圈
function circle() {
        if (slides[currentSlide + 1]) {
            ++currentSlide;
            step();
        }else{ currentSlide = 0; step() }
    }

然后在init中使用递归循环函数并调用它

 var  loop = function(){
                setTimeout(function(){ circle(); loop() }, 2000)
        }
 loop();
