Javascript Jquery插件帮助…需要添加我自己的功能
我正在尝试将我自己的功能添加到jQuery插件中，老实说，这并不顺利，我正在使用来自的easySlider 1.7 我的想法是使用分页版本，上面链接的站点上有一个例子，但是当用户单击一个编号的链接时，我希望它跳到该幻灯片保持，然后继续。下面是我的尝试，我将发布整个插件，并围绕我理解的部分和我添加的部分发表评论Javascript Jquery插件帮助…需要添加我自己的功能,javascript,jquery,jquery-plugins,Javascript,Jquery,Jquery Plugins,我正在尝试将我自己的功能添加到jQuery插件中，老实说，这并不顺利，我正在使用来自的easySlider 1.7 我的想法是使用分页版本，上面链接的站点上有一个例子，但是当用户单击一个编号的链接时，我希望它跳到该幻灯片保持，然后继续。下面是我的尝试，我将发布整个插件，并围绕我理解的部分和我添加的部分发表评论 /* * Easy Slider 1.7 - jQuery plugin * written by Alen Grakalic

感谢为链接或传递到滑块的整个元素添加悬停侦听器，当用户单击或悬停时，您可以清除自动前进超时。当他们离开时，您可以再次设置超时并继续 这样的东西会对整个元素起作用：
obj.hover(function() {
clearTimeout(timeout);
}, function() {
timeout = setTimeout(function(){
animate("next",false);
}, 2000);
});
那里。。。这应该是一个详尽的答案。希望这对你有帮助。祝你快乐 为链接或传递到滑块的整个元素添加悬停侦听器，当用户单击或悬停时，可以清除自动前进超时。当他们离开时，您可以再次设置超时并继续 这样的东西会对整个元素起作用：
