我如何使用按钮而不是悬停运行此 javascript 代码

How can I run this javascript code with a button instead of on hover?

本文关键字：运行 悬停 javascript 代码 何使用 按钮      更新时间：2023-09-26

我正在为网站使用 dev7studios 精益滑块，我想知道是否有人可以帮助 n00b 修改以下 javascript 以使用实际的暂停/播放按钮而不是默认的"悬停时暂停"功能。 

if(settings.pauseOnHover && settings.pauseTime && settings.pauseTime > 0){
    slider.hover(
        function () {
            clearTimeout(timer);
        },
        function () {
            doTimer();
        }
    );
}

提前感谢！

这里有一种方法可以做到这一点。请尝试使用此代码，并对您的图片，文件夹位置进行适当的调整，并将JS和CSS相应地放置在您的页面中。

祝你好运！
