基于javascript的無(wú)縫滾動(dòng)動(dòng)畫(huà)1

 更新時(shí)間：2020年08月07日 10:45:17   作者：司徒正美  
這篇文章主要介紹了基于javascript的無(wú)縫滾動(dòng)動(dòng)畫(huà)實(shí)現(xiàn)，文章通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

無(wú)縫滾動(dòng)好像是互聯(lián)網(wǎng)廣告最大的一個(gè)載體，可以用“無(wú)處不在”來(lái)形容它。不過(guò)它比起早期的閃光字體，浮動(dòng)廣告算進(jìn)步了。由于需求巨大，做前臺(tái)遲早會(huì)遇到它。我先給出結(jié)構(gòu)層部分，再慢慢講解其實(shí)現(xiàn)原理。

我自認(rèn)為這個(gè)結(jié)構(gòu)比網(wǎng)上那些純DIV的結(jié)構(gòu)好許多，起碼可以節(jié)省許多id與class。都不知那個(gè)傻冒最先提出“DIV+CSS”這個(gè)說(shuō)法，正確的說(shuō)法應(yīng)該是"xhtml+CSS"。換言之，就是在宏觀的布局上，用塊狀元素代替table，由于DIV的默認(rèn)樣式較少，因此比較常用，table則回歸和專(zhuān)注于數(shù)據(jù)顯示。在微觀的格式化上，用CSS代替原來(lái)b、big、center、i 、s、small、 strike、tt這些單純用于樣式設(shè)置的標(biāo)簽，很明顯CSS的能力比它們更強(qiáng)大。

實(shí)現(xiàn)原理與純CSS相冊(cè)點(diǎn)擊錨點(diǎn)切換相應(yīng)的圖片差不多，都是利用scrollTop。過(guò)程如下，因?yàn)槲覀冊(cè)O(shè)置dl的overflow為hidden，所以其左邊的滾動(dòng)條就不可見(jiàn)了。當(dāng)我們不斷增加其scrollTop時(shí)，它的內(nèi)容就不斷往上移動(dòng)，抵達(dá)到dl的可視區(qū)，把原來(lái)上面可見(jiàn)內(nèi)容擠掉，效果有點(diǎn)像設(shè)置了dl的margin-top為負(fù)數(shù)。繼續(xù)增加scrollTop，直到我們看到dd元素。這時(shí)，我們要看一下dt元素了，原本它為空元素，克隆了dd元素的圖片，其實(shí)是為了起一個(gè)遮眼法的效果。當(dāng)dt元素完全被dd元素?cái)D出dl的可視區(qū)時(shí)，我們驚訝地發(fā)現(xiàn)，這時(shí)dl元素可視區(qū)的樣子和它最初的樣式是一模一樣的。dd元素拷貝dt元素的圖片的作用也在于此。但繼續(xù)往下走，就肯定會(huì)露餡，因?yàn)閐d元素下面就沒(méi)有元素了，沒(méi)有圖片給我們顯示了。因此就在這一刻，我們把dl的元素scrollTop打回原形，重新回到dt元素圖片的顯示中。

那么問(wèn)題是這一刻我們?cè)鯓哟_定呢？關(guān)鍵是這句“dt元素完全被dd元素?cái)D出dl的可視區(qū)”，我們可以取dt元素的offsetHeight，這是dt元素的高加上padding與border，也可以取dd的offsetTop，這是dd元素頂部到dl元素頂部的距離。考慮到IE的怪癖模式，我決定先用offsetTop。既然要用offsetTop，我們需要指定offsetParent。不過(guò)許多教程都忘記了為dl元素設(shè)置position:relative。因?yàn)樵贗E6中，offsetParent直接為元素的父元素，而IE7，IE8與標(biāo)準(zhǔn)瀏覽器則為離它最近的被定了位的父級(jí)元素，沒(méi)有則為body元素。

上面的例子是向上滾動(dòng)，向下滾動(dòng)只不過(guò)是一開(kāi)始把dl元素的scrollTop設(shè)置成dd元素的offsetTop的值，然后遞減就是！

至于向左滾動(dòng)就相對(duì)麻煩些。首先我們要把圖片橫著排列，包括dt元素里面的，還有后來(lái)克隆到dd元素的，這要求用到浮動(dòng)。但這還未完，我們還要讓dt元素與dd元素橫著排列，于是我們就得對(duì)dl元素進(jìn)行設(shè)置浮動(dòng)。同時(shí)我們還得對(duì)dl元素的寬設(shè)置一個(gè)很大的值，目的是讓它不換行，并且能一字排開(kāi)所有圖片。我設(shè)置為1000%，即瀏覽器的寬的十倍。對(duì)于圖片，它浮動(dòng)時(shí)，左右之間都存在間隙，設(shè)置margin與padding為0這樣?，F(xiàn)的方法是無(wú)法去掉它們。只好走極端了，讓它們外套一個(gè)a元素，反正現(xiàn)實(shí)中當(dāng)我們點(diǎn)擊圖片時(shí)它一定會(huì)跳轉(zhuǎn)到另一個(gè)頁(yè)面或頁(yè)面的另一個(gè)地方，這就是用a元素來(lái)做的。由于a元素是內(nèi)聯(lián)元素，不存在盒子元素，它會(huì)向內(nèi)收縮，把圖片外面的空隙吞噬掉。最后，我們沒(méi)有理由一下子顯示所有圖片，因此我們?cè)僭赿l元素外面套一個(gè)div，在那里設(shè)置overflow與position與width等關(guān)鍵樣式。

javascript就沒(méi)多大改動(dòng)，只不過(guò)將offsetTop換成offsetLeft，scrollTop換成scrollLeft。因此熟悉CSS，真是好處多多。

var Marquee = function(id){
 try{document.execCommand("BackgroundImageCache", false, true);}catch(e){};
 var container = document.getElementById(id),
 original = container.getElementsByTagName("dt")[0],
 clone = container.getElementsByTagName("dd")[0],

 var rolling = function(){

 container.scrollLeft = 0;
 }else{
 container.scrollLeft++;
 }
 }
 var timer = setInterval(rolling,speed)//設(shè)置定時(shí)器
 container.onmouseover=function() {clearInterval(timer)}//鼠標(biāo)移到marquee上時(shí)，清除定時(shí)器，停止?jié)L動(dòng)
