<ul>
    <li><a href="#">one</a></li>
    <li><a href="#">two</a></li>
    <li><a href="#">three</a></li>
</ul>

我想li一次只显示一个使用幻灯片效果,就是这样。我想避免将插件用于这样简单的事情。

在此先感谢您的帮助。

我为你做了一些简单的事情(根据你的描述),只是为了给你指明正确的方向:

在这里查看:http: //jsfiddle.net/meo/ACenH/234/

function slider(container, delay){
$container = $(container) // select the container elements and store them in a variable

if ( !$container.length ){ return fasle; } // checks if the slider exists in your dom. if not the function ends here...

    var slides = $container.length, // gives back the total LI's you have
        slide = 0 // set the actual li to show

        setInterval(function(){ // set a Interval for your main function
            if (slide == slides - 1) { // if the actual slide is equal the total slides (-1 because eq is 0 based and length gives back the number of elements in the jQuery object) the slide counter is set to 0
               $container.slideDown(); // and all slides a shown again
               slide = 0;
            } else {
              $container.eq(slide).slideUp(); //slides the selected slide up i think you could think of a solution with .next() instead of eq() 
              slide++; // slide counter +1
            }

        }, delay)

}

slider('ul > li', 2000); // call your slider function

您的问题已经提到 jquery 作为选择的 javascript 框架。您可以开始的最佳位置是关于隐藏的 jquery 文档:

http://api.jquery.com/hide/

和滑动:

http://api.jquery.com/slideUp/
http://api.jquery.com/slideDown/
http://api.jquery.com/slideToggle/
