今天在项目中需要一个图片跑马灯的效果 , 就用js写了一个
直接上代码吧:
css代码:
*{margin:0;padding:0;} .clearfix:after { content: ""; display: table; clear: both; } .clearfix: { *zoom: 1; } #div1{ width:1200px;height:200px;margin:100px auto;position:relative;background:red; overflow:hidden; } #div1 ul{ position:absolute;left:0;top:0; } #div1 ul li{ float:left; list-style:none; }
HTML代码:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <body> <div id="div1"> <ul class="clearfix"> <li><img src="image/1.jpg" alt=""></li> <li><img src="image/2.jpg" alt=""></li> <li><img src="image/3.jpg" alt=""></li> <li><img src="image/4.jpg" alt=""></li> </ul> </div> </body> </html>
js代码:
window.onload = function(){ // 1. offsetLeft:获取物体的左边距 var oDiv = document.getElementById(‘div1‘); var oUl = oDiv.getElementsByTagName(‘ul‘)[0]; var aLi = oUl.getElementsByTagName(‘li‘); oUl.innerHTML = oUl.innerHTML+oUl.innerHTML; oUl.style.width = aLi[0].offsetWidth*aLi.length+‘px‘; function autoPlay(){ if(oUl.offsetLeft<-oUl.offsetWidth/2){ oUl.style.left = ‘0‘; } oUl.style.left = oUl.offsetLeft-2+‘px‘ }; var timer= setInterval(autoPlay,30) oDiv.onmouseover = function(){ clearInterval(timer); }; oDiv.onmouseout = function(){ timer = setInterval(autoPlay,30) } }
图片直接替换成自己的图片就可以使用
