javascript - 循环浏览图像直到悬停jquery

Question

我希望图像单独循环显示，比如每 2 秒更改一次图像，然后在悬停相关链接时切换到正确的图像。以下是我到目前为止所取得的成就。现在，我得到了要在悬停时显示的图像，但我不确定如何让它们循环。

$("#one").on({
mouseover: function () {
    timer = setTimeout(function () {
        $("#first").removeClass('hidden').css('opacity', '1');
    }, 300);
},
mouseout: function () {
    clearTimeout(timer);
    $("#first").css({
        'opacity': '0'
    }).addClass('hidden');
}
});

您的 HTML 中有一些损坏的图像链接。但这应该可以解决问题: https://jsfiddle.net/pengyanb/st47yxqb/6/
