javascript實現(xiàn)圖片輪換動作方法

 更新時間：2020年08月07日 10:06:50   作者：司徒正美  
這篇文章主要介紹了javascript實現(xiàn)圖片輪換動作方法，文章通過示例代碼介紹的非常詳細(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

圖片輪換是一種相當(dāng)復(fù)雜的技術(shù)，早些年基本用flash實現(xiàn)。這里有一個鏈接，教大家如何用flash實現(xiàn)它的。之所以用flash，是因為flash是基于幀的，這與圖片輪換的原理相當(dāng)接近。為了模擬幀的效果，我們要用到overflow把多余的部分遮罩掉，也就是flash中常說的遮罩層。在Flash中，連時間軸都是可視的，而我們則全憑想象力與數(shù)學(xué)來計算現(xiàn)在是到了哪一張圖。加之，flash有Robert Penner大神的緩動公式，那實在太耀眼，直到script.aculo.us類庫搞出自己的緩動公式，才扭轉(zhuǎn)局面。

我們來看一看圖片輪換的結(jié)構(gòu)層。它應(yīng)該包含框體，圖片展示區(qū)，圖片滑動層與分頁欄。原諒我制造這么多詞匯，因為沒有個名詞講解就難以為繼了，前人也沒有做這樣的總結(jié)，個個都不愿意分享一下?？蝮w就是一個div元素，作用有兩個：提供相冊的邊框與作為分頁欄的包含塊。如果不清楚什么叫包含塊（containing block）的話，自己查閱CSS權(quán)威指南吧。接著下來圖片展示區(qū)與圖片滑動層，也就是我實現(xiàn)新式無縫滾動的那一種結(jié)構(gòu)，一個很干凈的無序列表，所有難點都轉(zhuǎn)移到設(shè)置它的CSS上。至于圖片展示區(qū)就是ul元素，大小為一張圖片的大??；圖片滑動層就是那個li元素，也只有一個li元素而已，利用CSS強(qiáng)制把它里面的圖片不換行向左浮動，并設(shè)置li元素一個很大很大的寬度，好讓它一行容納所有圖片。分頁欄就是一個包含許多鏈接的span元素，和普通的水平菜單差不多，只不過要用絕對定位它安置到框體的右下角。

這個和我以前的系列一樣，不用JS也可以點擊實現(xiàn)切換。不過以前是用錨點來改變scrollTop的值，現(xiàn)在是改變scrollLeft的值。

如果不使用緩動效果，很簡單。

var Rotate = function(id){
 try{document.execCommand("BackgroundImageCache", false, true);}catch(e){};
 var container = document.getElementById(id),
 slide = container.getElementsByTagName("li")[0];
 slide.innerHTML += slide.innerHTML;
 var item = slide.getElementsByTagName("a"),
 critical = item[item.length/2].offsetLeft,//臨界值
 distance = critical/(item.length/2),
 delta = - distance;
 (function(){//實現(xiàn)自動輪換圖片
 setTimeout(function(){
  delta = delta - distance;
  if(delta < -critical){
  delta = - distance;
  }
  slide.style.left = delta + "px";//★★★★★★★★
  setTimeout(arguments.callee,1500)
 },1500)
 })()
}

要使用緩動，就要動用我的緩動公式與transition函數(shù)，在星號的位置中調(diào)用。

我們也可以像第一部分那樣加入一個信息欄，這樣程序就擁有三個定時器了，看起來讓人有點頭暈，現(xiàn)實中不提倡這樣做，這里只是試范一下如何使用transition的回調(diào)函數(shù)罷了。

//動態(tài)生成li元素并把它插入到DOM樹中。
var tip = document.createElement("li");//信息欄
tip.style.cssText = "position:absolute;bottom:0;width:400px;height:40px;line-height:40px;text-indent:2em;";
slide.parentNode.appendChild(tip);
if(!+"\v1"){
 tip.style.cssText += "color:#369;background:#fff;filter:alpha(opacity=50)";
}else{
 tip.style.cssText += "color:#fff;background: rgba(164, 173, 183, .65);";
}

有的人很懶，不喜歡點擊，想在按鈕上一掠而過也能看到效果。這簡單，我們把綁定函數(shù)獨立出來，分別綁定到onclick事件與onmouseover事件上就行了?，F(xiàn)在我們換一個緩動公式，反正這東西多著呢。比如這個pulse，像蛇信子一樣來回多次振動（默認(rèn)5次，有第二個參數(shù)可以自己調(diào)，我調(diào)到10次），非常有意思。你們可以試試一下子掠過所有按鈕，效果是何等的炫目！
