鼠标悬停在元素上时如何停止/开始循环滑块？

Question

制作滑块我遇到了一个问题。当我将按钮悬停在图像下方（它们是标签）时，滑块的循环必须停止。当它出局时 - 它会回到循环中。不能理解我错在哪里。请参阅代码段或in this link.

中的代码

$(document).ready(function(){
var loop = true;
var quantity = $('input[type="radio"]').length;
function changeTo(i) {
    setTimeout(function () {

        if (loop) {
          number = i%(quantity);
            $("label").removeClass('active');
            $("label:eq(" + number + ")").trigger("click").addClass('active');
            changeTo(i+1);
        }
    }, 2000);
}
changeTo(0);

$( "label" ).on( "mouseover", function() {
loop = false;
  $("label").removeClass('active');
  $(this).addClass('active').trigger('click');
}).on('mouseout', function(){
  loop = true;
});

});

有关工作示例，请参阅此JSFiddle。

但是，如果您的停留时间超过超时时间，则不会调用changeto（），您需要将changeto（）添加到“mouseleave”处理程序。

$(document).ready(function(){
var loop = true;
var quantity = $('input[type="radio"]').length;
function changeTo(i) {
    setTimeout(function () {

        if (loop) {
          number = i%(quantity);
            $("label").removeClass('active');
            $("label:eq(" + number + ")").trigger("click").addClass('active');
            changeTo(i+1);
        }
    }, 2000);
}
changeTo(0);

$( "label" ).on( "mouseover", function() {
loop = false;
  $("label").removeClass('active');
  $(this).addClass('active').trigger('click');
}).on('mouseout', function(){
  loop = true;
  changeTo(0)
});

});
