JS實現的文字與圖片定時切換效果代碼

這篇文章主要介紹了JS實現的文字與圖片定時切換效果代碼,可實現定時切換及鼠標點擊切換兩種效果,涉及JavaScript鼠標事件控制頁面樣式的相關技巧,需要的朋友可以參考下

本文實例講述了JS實現的文字與圖片定時切換效果代碼。分享給大家供大家參考。具體如下：

這是近來門戶們都喜歡用的特效，左側是一個大圖片，右側是對應文字，鼠標移動時，對應行的文字會變化，圖片也相應的切換，如果沒有鼠標動作時，它會自己播放，播放時間可調整，個人感覺挺不錯的導航效果。

運行效果截圖如下：

在線演示地址如下：

具體代碼如下：

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>文字與圖片切換</title>
<style>
*{margin:0;padding:0;border:0;list-style:none}

.focusPic .focusTitle{width:240px;float:right; font-size:14px; text-align:left;}
.focusPic .focusTitle li{height:28px; line-height:28px; cursor:pointer; font-size:12px; padding-left:10px; }
.focusPic .focusTitle li a ,.focusPic .focusTitle li a:visited { color:#000;}
