Html、js图片轮播代码

Html、js图片轮播代码现在基本上每个网站都有一个自动轮播的banner广告图，在没有任何按钮的情况下，图片在规定的时间内进行自动切换。

下面是html、js 图片轮播代码详情。

代码效果图实例：第一秒：第二秒：第三秒：详细代码如下：Html代码部分：<body><ul class="banner"><li><img src="images/1.jpg"></li><li><img src="images/2.jpg"></li><li><img src="images/3.jpg"></li></ul></body>Css代码部分：<style type="text/css">ul,li{margin:0px;padding:0px}li{list-style:none}.banner{width:630px;height:250px;margin:100px auto;overflow:hidden;cursor:pointer} </style>Javascript代码部分：<script type="text/javascript"src="jquery.js"></script><script type="text/javascript">$(function(){var timer=setInterval(function(){if($(".banner li:last").is(":hidden")){$(".banner li:visible").addClass("on");$(".banner li[class=on]").next().fadeIn("slow");$(".banner li[class=on]").hide().removeClass("on");}else{$(".banner li:last").hide();$(".banner li:first").fadeIn("slow");}},2000)$(".banner li").hover(function(){clearInterval(timer);},function(){timer=setInterval(function(){if($(".banner li:last").is(":hidden")){$(".banner li:visible").addClass("on");$(".banner li[class=on]").next().fadeIn("slow");$(".banner li[class=on]").hide().removeClass("on");}else{$(".banner li:last").hide();$(".banner li:first").fadeIn("slow");}},2000)})})</script>【Jquery.js】是一个jquery库，只要百度一下搜索“jquery”下载这个文件就行。

JavaScript代码实现图片循环滚动效果

JavaScript代码实现图⽚循环滚动效果1.概述循环滚动图⽚，不仅可以增添Web页⾯的动态效果，⽽且可以节省页⾯空间，有效地保证在有限的页⾯中显⽰更多的图⽚。

2.技术要点主要应⽤setTimeout()⽅法实现图⽚的循环滚动效果。

setTimeout()⽅法的语法格式如下：setTimeout（function,milliseconds,[arguments]）参数说明：a. function：要调⽤的JavaScript⾃定义函数名称。

b. Milliseconds：设置超时时间（以毫秒为单位）。

功能：经过超时时间后，调⽤函数。

此值可以⽤clearTimeout()函数清除。

3.具体实现（1）在页⾯的合适位置添加⼀个id属性为demo的<div>标记，并在该标记中添加表格及要要滚动显⽰的图⽚。

关键代码如下：<div id="demo" style=" overflow: hidden; width: 455px; height: 166px;"><table border="0" cellspacing="0" cellpadding="0"><tr><td valign="top" id="marquePic1"><table width="455" border="0" align="center" cellpadding="0" cellspacing="0" ><tr align="center"><%for(int i=1;i<8;i++){%><td> <img src="Images/<%=i%>.jpg" width="118" height="166" border="1"> </td><%}%></tr></table></td><td id="marquePic2" width="1"></td></tr></table></div>（2）编写⾃定义的JavaScript函数move()，⽤于实现⽆间断的图⽚循环滚动效果。

js实现图片旋转的三种方法

js实现图⽚旋转的三种⽅法1 使⽤jQueryRotate.js实现⽰例代码：复制代码代码如下:<!DOCTYPE html><html><head><title></title><style type="text/css">#div1 {width: 800px;height: 600px;background-color: #ff0;position: absolute;}.imgRotate {width: 100px;height: 80px;position: absolute;top: 50%;left: 50%;margin: -40px 0 0 -50px;}</style></head><body><div id="div1"><img id="img1" class="imgRotate" src="/img/logo-yy.gif" /><input id="input2" type="button" value="btn2"></input></div></body><script type="text/javascript" src="jquery.min.js"></script><script type="text/javascript" src="jQueryRotate.js"></script><script type="text/javascript">var num = 0;$("#input2").click(function(){num ++;$("#img1").rotate(90*num);});</script></html>测试结果：chrome下效果正常，旋转后img对象仍为img对象；ie8下效果正常，但旋转后img对象变为下⾯对象，由于对象变化，若旋转后仍按原来⽅法获取img对象，则会报js错误。

javascript实现多张图片左右无缝滚动效果

javascript实现多张图⽚左右⽆缝滚动效果结构：box包含ul，ul包含4个li；ul绝对定位。

复制li-1、li-2到第li-4后⾯，为了区分于li-1、li-2，内容改为li-5、li-6，颜⾊不变。

此时ul包含6个li。

需要注意的是，移动的是ul这个⼤盒⼦⽽不是li。

原理：当ul 绝对定位的left 值等于（li-1+li-2+li-3+li-4）的宽度时，利⽤JavaScript快速复原left 值为0 。

此时请注意盒⼦⾥⾯数字和颜⾊的变化！效果图：⽰例代码：<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><meta http-equiv="X-UA-Compatible" content="ie=edge"><title>Document</title><style media="screen">*{padding: 0;margin: 0;}ul,li {list-style: none;}img {vertical-align: top;}#box{width: 400px;height: 100px;margin: 100px auto;background-color: pink;position: relative;overflow: hidden;}#box ul {width: 2000px;position: absolute;left: 0;top: 0;}#box li {float: left;}.aa {width: 200px;height: 100px;}.li-1{background-color: #f6e659;}.li-2{background-color: #57fa4f;}.li-3{background-color: #3a8ef1;}.li-4{background-color: #c057f1;}</style></head><body><div id="box"><ul><li class="li-1 aa">li-1</li><li class="li-2 aa">li-2</li><li class="li-3 aa">li-3</li><li class="li-4 aa">li-4</li><li class="li-1 aa">li-5</li><li class="li-2 aa">li-6</li></ul></div></body></html><script type="text/javascript">var box = document.getElementById("box");var ul = box.children[0];var num = 0;timer = setInterval(fn,10);function fn() {num--;num <= -800 ? num = 0 : num;ul.style.left = num + "px";}</script>以上就是本⽂的全部内容，希望本⽂的内容对⼤家的学习或者⼯作能带来⼀定的帮助，同时也希望多多⽀持！。

使用JS实现图片轮播滚动跑马灯效果

使⽤JS实现图⽚轮播滚动跑马灯效果我的第⼀篇⽂章、哈哈、有点⼩鸡冻。

之前在百度搜索“图⽚轮播”、“图⽚滚动”，结果都是那种可以左右切换的。

也是我们最常见的那种。

可能是搜索关键字的问题吧。

JS实现轮播图效果的3种简单方法

JS实现轮播图效果的3种简单⽅法本⽂实例为⼤家分享了3种⽅法实现JS轮播图效果的具体代码，供⼤家参考，具体内容如下Js实现轮播图01实现思路这可能是轮播图最简单点的实现之⼀，通过更改图⽚的src来实现该效果，⾸先需要将图⽚命名格式统⼀⽐如pic01.jpg，pic02.jpg…,再通过js使⽤定时器去改变img标签⾥⾯的src图⽚链接的名字来实现切换效果。

代码如下：实现效果<!DOCTYPE html><html><head><meta charset="utf-8"><title>轮播图实现01</title><style type="text/css">.lunbo{width: 900px;height: 400px;margin:100px auto;}.lunbo img{width: 100%;height:100%;}</style></head><body><div class="lunbo"><img id="lunbo_img" src="./pic/img3.jpeg" ></div><script>var index = 1;function lunbo(){index ++ ;//判断index是否⼤于3if(index > 3){index = 1;}//获取img对象var img = document.getElementById("lunbo_img");img.src = "./pic/img"+index+".jpeg";}//2.定义定时器setInterval(lunbo,2000);/*切记定时器⾥调⽤lunbo⽅法不能加(),setInterval(lunbo,2000);如果加()会执⾏lunbo（）⽅法，⽽导致定时器没⽤。

JS+html--实现图片轮播

JS+html--实现图⽚轮播⼤家肯定见过某些⽹站⼀个炫酷的页⾯，就是图⽚轮播，也就是我们常说的幻灯⽚播放。

对于初学者来说，可能会有点头疼，没关系，⼩李在这给⼤家献上⾃⼰刚刚写好的关于图⽚轮播的代码。

以下功能的实现⽤了jQuery，⼤家可以去⽹上找⼀下关于jQuery的资源下载使⽤。

前端框架技术应用中的图片轮播与滑动效果实现方法在现代网页设计中，图片轮播和滑动效果成为了提升用户体验的重要手段之一。

通过动态展示多张图片，可以有效地吸引用户的注意力，增加页面的互动性和吸引力。

在前端开发中，有多种框架和技术可供选择，用于实现图片轮播和滑动效果。

本文将介绍一些常见的方法和技术，帮助您实现出色的图片轮播和滑动效果。

一、jQuery插件：SlickSlick是一款流行的jQuery插件，用于创建响应式且可自定义的轮播组件。

它提供了许多选项，供开发者根据项目需求来自定义轮播效果。

使用Slick，您可以轻松地添加自动播放、循环滚动、切换效果和其他配置选项。

为了使用Slick，您需要先引入jQuery和Slick的相关文件。

然后，在HTML中定义一个包含多个图片的容器，给每个图片一个自定义的类名。

接着，在JavaScript文件中使用Slick的初始化函数来创建轮播效果，可以通过参数来设置轮播的速度、切换效果等。

最后，通过自定义CSS来调整轮播容器的样式。

二、CSS框架：BootstrapBootstrap是一个流行的HTML、CSS和JavaScript开发框架，提供了许多组件和工具，用于构建现代化的响应式网页。

其中，Carousel组件可以用来实现图片轮播效果。

Bootstrap的Carousel组件具有丰富的选项，可以使用CSS类和JavaScript函数来实现滑动、淡入淡出等效果。

使用Bootstrap Carousel，您需要先引入Bootstrap的相关文件。

然后，在HTML中添加Carousel组件的HTML结构，包括一个包裹图片的容器和相应的控制元素。

您可以使用自定义的CSS类来调整样式，并使用JavaScript函数来初始化Carousel组件和设置参数。

三、React框架：React Slick如果您正在使用React框架进行开发，那么React Slick可能是一个不错的选择。

图片轮播（左右切换）--JS原生和jQuery实现

图⽚轮播（左右切换）--JS原⽣和jQuery实现图⽚轮播(左右切换)--js原⽣和jquery实现左右切换的做法基本步骤跟上⼀篇⽂章类似，只不过修改了⼀些特定的部分（1）⾸先是页⾯的结构部分对于我这种左右切换式1.⾸先是个外围部分（其实也就是最外边的整体wrapper)2.接着就是你设置图⽚轮播的地⽅（也就是⼀个banner吧）3.然后是⼀个图⽚组（可以⽤新的div 也可以直接使⽤ ul-->li形式）4.然后是图⽚两端的左箭头和右箭头5.然后是⼀个透明背景层，放在图⽚底部6.然后是⼀个图⽚描述info层，放在透明背景层的左下⾓（div 或 ul-->li)7.然后是⼀个按钮层，⽤来定位图⽚组的index吧,放在透明背景层的右下⾓(div 或 ul-->li)由此，可以先构造出html结构<div id="wrapper"><div id="banner"><ul class="imgList"><li><a href="#"><img src="./img/test1.jpg" width="400px" height="200px" alt="puss in boots1"></a></li><li><a href="#"><img src="./img/test2.jpg" width="400px" height="200px" alt="puss in boots2"></a></li><li><a href="#"><img src="./img/test3.jpg" width="400px" height="200px" alt="puss in boots3"></a></li><li><a href="#"><img src="./img/test4.jpg" width="400px" height="200px" alt="puss in boots4"></a></li><li><a href="#"><img src="./img/test5.jpg" width="400px" height="200px" alt="puss in boots5"></a></li></ul><img src="./img/prev.png" width="20px" height="40px" id="prev"><img src="./img/next.png" width="20px" height="40px" id="next"><div class="bg"></div><ul class="infoList"><li class="infoOn">puss in boots1</li><li>puss in boots2</li><li>puss in boots3</li><li>puss in boots4</li><li>puss in boots5</li></ul><ul class="indexList"><li class="indexOn">1</li><li>2</li><li>3</li><li>4</li><li>5</li></ul></div></div>相对于之前，知识增多了两个箭头img标签（2）CSS样式部分（图⽚组的处理）跟淡⼊淡出式就不⼀样了淡⼊淡出只需要显⽰或者隐藏对应序号的图⽚就⾏了，直接通过display来设定左右切换式则是采⽤图⽚li 浮动，⽗层元素ul 总宽为总图⽚宽，并设定为有限banner宽度下隐藏超出宽度的部分然后当想切换到某序号的图⽚时，则采⽤其ul 定位 left样式设定相应属性值实现⽐如显⽰第⼀张图⽚初始定位left为0px, 要想显⽰第⼆张图⽚则需要left:-400px 处理<style type="text/css">body,div,ul,li,a,img{margin: 0;padding: 0;}ul,li{list-style: none;}a{text-decoration: none;}#wrapper{position: relative;margin: 30px auto;width: 400px;height: 200px;}#banner{position:relative;width: 400px;height: 200px;overflow: hidden;}.imgList{position:relative;width:2000px;height:200px;z-index: 10;overflow: hidden;}.imgList li{float:left;display: inline;}#prev,#next{position: absolute;top:80px;z-index: 20;cursor: pointer;opacity: 0.2;filter:alpha(opacity=20);}#prev{left: 10px;}#next{right: 10px;}#prev:hover,#next:hover{opacity: 0.5;filter:alpha(opacity=50);}.bg{position: absolute;bottom: 0;width: 400px;height: 40px;z-index:20;opacity: 0.4;filter:alpha(opacity=40);background: black;} .infoList{position: absolute;left: 10px;bottom: 10px;z-index: 30;}.infoList li{display: none;}.infoList .infoOn{display: inline;color: white;}.indexList{position: absolute;right: 10px;bottom: 5px;z-index: 30;}.indexList li{float: left;margin-right: 5px;padding: 2px 4px;border: 2px solid black;background: grey;cursor: pointer;}.indexList .indexOn{background: red;font-weight: bold;color: white;}</style>（3）页⾯基本已经构建好久可以进⾏js的处理了⼀、jQuery⽅式照常先说jq处理1.全局变量等var curIndex = 0, //当前indeximgLen = $(".imgList li").length; //图⽚总数2.⾃动切换定时器处理// 定时器⾃动变换2.5秒每次var autoChange = setInterval(function(){if(curIndex < imgLen-1){curIndex ++;}else{curIndex = 0;}//调⽤变换处理函数changeTo(curIndex);},2500);3.为左右箭头添加事件处理左箭头//左箭头滑⼊滑出事件处理$("#prev").hover(function(){//滑⼊清除定时器clearInterval(autoChange);},function(){//滑出则重置定时器autoChangeAgain();});//左箭头点击处理$("#prev").click(function(){//根据curIndex进⾏上⼀个图⽚处理curIndex = (curIndex > 0) ?

(++curIndex) : 0;changeTo(curIndex);});其中autoChangeAgain()就是⼀个重置定时器函数//清除定时器时候的重置定时器--封装function autoChangeAgain(){autoChange = setInterval(function(){if(curIndex < imgLen-1){curIndex ++;}else{curIndex = 0;}//调⽤变换处理函数changeTo(curIndex);},2500);}其中changeTo()就是⼀个图⽚切换的处理函数function changeTo(num){var goLeft = num * 400;$(".imgList").animate({left: "-" + goLeft + "px"},500);$(".infoList").find("li").removeClass("infoOn").eq(num).addClass("infoOn");$(".indexList").find("li").removeClass("indexOn").eq(num).addClass("indexOn");}每传⼊⼀个图⽚序号，则按理进⾏goLeft4.为右下⾓的那⼏个li 按钮绑定事件处理//对右下⾓按钮index进⾏事件绑定处理等$(".indexList").find("li").each(function(item){$(this).hover(function(){clearInterval(autoChange);changeTo(item);curIndex = item;},function(){autoChangeAgain();});});jq就是这样，简便，原⽣代码量就有些多了完整代码1<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 2<html xmlns="/1999/xhtml">3<head>4<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>5<title>图⽚轮播 jq(左右切换)</title>6<style type="text/css">7 body,div,ul,li,a,img{margin: 0;padding: 0;}8 ul,li{list-style: none;}9 a{text-decoration: none;}1011 #wrapper{position: relative;margin: 30px auto;width: 400px;height: 200px;}12 #banner{position:relative;width: 400px;height: 200px;overflow: hidden;}13 .imgList{position:relative;width:2000px;height:200px;z-index: 10;overflow: hidden;}14 .imgList li{float:left;display: inline;}15 #prev,16 #next{position: absolute;top:80px;z-index: 20;cursor: pointer;opacity: 0.2;filter:alpha(opacity=20);}17 #prev{left: 10px;}18 #next{right: 10px;}19 #prev:hover,20 #next:hover{opacity: 0.5;filter:alpha(opacity=50);}21 .bg{position: absolute;bottom: 0;width: 400px;height: 40px;z-index:20;opacity: 0.4;filter:alpha(opacity=40);background: black;}22 .infoList{position: absolute;left: 10px;bottom: 10px;z-index: 30;}23 .infoList li{display: none;}24 .infoList .infoOn{display: inline;color: white;}25 .indexList{position: absolute;right: 10px;bottom: 5px;z-index: 30;}26 .indexList li{float: left;margin-right: 5px;padding: 2px 4px;border: 2px solid black;background: grey;cursor: pointer;}27 .indexList .indexOn{background: red;font-weight: bold;color: white;}28</style>29</head>30<body>31<div id="wrapper">32<div id="banner">33<ul class="imgList">34<li><a href="#"><img src="./img/test1.jpg" width="400px" height="200px" alt="puss in boots1"></a></li>35<li><a href="#"><img src="./img/test2.jpg" width="400px" height="200px" alt="puss in boots2"></a></li>36<li><a href="#"><img src="./img/test3.jpg" width="400px" height="200px" alt="puss in boots3"></a></li>37<li><a href="#"><img src="./img/test4.jpg" width="400px" height="200px" alt="puss in boots4"></a></li>38<li><a href="#"><img src="./img/test5.jpg" width="400px" height="200px" alt="puss in boots5"></a></li>39</ul>40<img src="./img/prev.png" width="20px" height="40px" id="prev"> 41<img src="./img/next.png" width="20px" height="40px" id="next"> 42<div class="bg"></div>43<ul class="infoList">44<li class="infoOn">puss in boots1</li>45<li>puss in boots2</li>46<li>puss in boots3</li>47<li>puss in boots4</li>48<li>puss in boots5</li>49</ul>50<ul class="indexList">51<li class="indexOn">1</li>52<li>2</li>53<li>3</li>54<li>4</li>55<li>5</li>56</ul>57</div>58</div>59<script type="text/javascript" src="./js/jquery.min.js"></script>60<script type="text/javascript">61var curIndex = 0, //当前index62 imgLen = $(".imgList li").length; //图⽚总数63// 定时器⾃动变换2.5秒每次64var autoChange = setInterval(function(){65if(curIndex < imgLen-1){66 curIndex ++;67 }else{68 curIndex = 0;69 }70//调⽤变换处理函数71 changeTo(curIndex);72 },2500);7374//左箭头滑⼊滑出事件处理75 $("#prev").hover(function(){76//滑⼊清除定时器77 clearInterval(autoChange);78 },function(){79//滑出则重置定时器80 autoChangeAgain();81 });82//左箭头点击处理83 $("#prev").click(function(){84//根据curIndex进⾏上⼀个图⽚处理85 curIndex = (curIndex > 0) ?

scrollLeft,scrollTop,滚动代码的总结

scrollLeft,scrollTop,滚动代码的总结scrollLeft,scrollTop,滚动代码的总结今天和兄弟一起研究了一下横向和竖向图片滚动的代码，很兴奋，因为解决了几个小问题第一个：for(var i=1;i<50;i++){document.getElementById("TextBox1").scrollTop++; document.getElementById("TextBox1").scrollLeft++;}我刚开始的时候写成了for(int i=1;i<50;i++){//document.getElementById("TextBox1").scrollTop++; document.getElementById("TextBox1").scrollLeft++;}IE提示错误，Exception ;我半天不知道怎么回事，最后才发现是犯了个很低级的错误，javascript中的变量用var定义，可以不定义！下面入正题clientHeight大家对clientHeight 都没有什么异议，都认为是内容可视区域的高度，也就是说页面浏览器中可以看到内容的这个区域的高度。

offsetHeightIE、Opera 认为offsetHeight = clientHeight + 滚动条+ 边框。

NS、FF 认为offsetHeight 是网页内容实际高度，可以小于clientHeight。

scrollHeightIE、Opera 认为scrollHeight 是网页内容实际高度，可以小于clientHeight。

NS、FF 认为scrollHeight 是网页内容高度，不过最小值是clientHeight。

简单地说clientHeight 就是透过浏览器看内容的这个区域高度。
