JQuery實現(xiàn)左右滾動菜單特效

更新時間：2015年09月28日 17:01:37 投稿：lijiao

這篇文章主要介紹了jquery實現(xiàn)左右滑動菜單效果代碼，涉及jquery鼠標(biāo)事件相關(guān)技巧，具有一定參考借鑒價值，需要的朋友可以參考下

經(jīng)過了半天的時間，這個使用JQuery開發(fā)出來的左右滾動菜單功能也算是完成了，暫時還沒有發(fā)現(xiàn)錯誤的現(xiàn)象?，F(xiàn)在把代碼完整的代碼拿出來分享！

scrollable.js

JQuery左右滾動菜單特效腳本代碼引用片段：

scrollable = function(content, render, options, beforeScroll) {

  * 
  * 注意: 
  *  1. content必須自己指定寬度. 如果其中的元素使用塊元素, 請使用float: left向左浮動. 
  *  2. 使用時, 盡量自定義樣式, 由于本人水平欠佳, 不能作出更加通用的東西, 呵呵. 
  * 
  * 參數(shù)解釋 
  * content: 內(nèi)容元素, 可以是選擇器或JQUERY封裝的DOM元素 
  * render: 渲染到的目標(biāo)容器, 可以是選擇器或JQUERY封裝的DOM元素 
  * options: 選項 
  *  scrollable_class: 整體scrollable的外框架樣式 , 默認(rèn): ui-scrollable 
  *  scrollable_left_class: 左按鈕的樣式, 默認(rèn): ui-scrollable-left 
  *  scrollable_container_class: 內(nèi)容容器的樣式, 默認(rèn): ui-scrollable-container 
  *  scrollable_right_class: 右按鈕的樣式, 默認(rèn): ui-scrollable-right 
  *  delay: 鼠標(biāo)放上或點擊按鈕時兩次移動之間的時間間隔, 整數(shù) 
  *  speed: 鼠標(biāo)放上按鈕時, 一次移動的距離, 整數(shù) 
  *  speedup: 鼠標(biāo)點下按鈕時, 一次移動的距離, 整數(shù) 
  *  resizeEvent: 是否監(jiān)聽窗口改變大小的事件, 布爾值, 
  *   監(jiān)聽窗口改變大小時, 在刷新頁面后, 感覺顯示有點別扭, 所以默認(rèn)了false 
  * beforeScroll: 內(nèi)容滾動時候的事件回調(diào)方法. 
  *  接受參數(shù)(兩個對象): 第一個是滾動前內(nèi)容左右位置, 第二個是滾動后內(nèi)容左右位置. 
  *  注意: 該事件可以使內(nèi)容不受邊界限制的滾動.

當(dāng)然，我們還需要引用JQuery框架文件，我這里用的是jquery-1.4.2.min.js，自己可以在網(wǎng)上搜索下載，我就不上傳到這里了。整個JQuery左右滾動菜單特效就是這個樣子了，自己覺得還行，希望能幫到一些有需要的朋友。
