jQuery實現(xiàn)列表自動滾動循環(huán)滾動展示新聞，鼠標懸停時停止?jié)L動并提示，離開后，繼續(xù)滾動，實現(xiàn)的代碼如下，需要的朋友可以看看

需要在頁面中一個小的區(qū)域循環(huán)滾動展示新聞（公告、活動、圖片等等），并且，鼠標懸停時停止?jié)L動并提示，離開后，繼續(xù)滾動。

上干貨

html：

復制代碼代碼如下:

<div id="news">

<ul>

<li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="aaaaaaaaaaaaaaa">aaaaaaaaaaaaaaa</a></li>

<li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="bbbbbbbbbbbbbbb">bbbbbbbbbbbbbbb</a></li>

<li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="ccccccccccccccc">ccccccccccccccc</a></li>

<li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="ddddddddddddddd">ddddddddddddddd</a></li>

<li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="eeeeeeeeeeeeeee">eeeeeeeeeeeeeee</a></li>

<li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="fffffffffffffff">fffffffffffffff</a></li>

<li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="ggggggggggggggg">ggggggggggggggg</a></li>

</ul>

</div>

css：

復制代碼代碼如下:

ui,li {

list-style: none;

}

#news{

height: 75px;

overflow: hidden;

}

關鍵是js文件：

復制代碼代碼如下:

$(function() {
var $this = $("#news");
var scrollTimer;
$this.hover(function() {
clearInterval(scrollTimer);
}, function() {
scrollTimer = setInterval(function() {
scrollNews($this);
}, 2000);
}).trigger("mouseleave");

主要就是對hover、setInterval、clearInterval、animate這些方法以及marginTop屬性（marginLeft、top、left等等）的理解和運用，需要注意的是，如果不加.trigger("mouseleave")，在網(wǎng)頁初始化的時候列表不會滾動，還有appendTo能直接移動元素，就這些了。
