本文为大家分享了javascript图片滑动效果实现方法,具体内容如下,先看一下效果图:
鼠标滑过那张图,显示完整的哪张图,移除则复位:
简单的CSS加JS操作DOM实现:
<!doctype html> <html> <head> <meta charset="UTF-8"> <title>sliding doors</title> <link rel="stylesheet" href="styles/reset.css" /> <link rel="stylesheet" href="styles/slidingdoors.css" /> <script src="scripts/slidingdoors.js"></script> </head> <body> <div id='container'> <img src="images/door1.png" alt="1080P神器" title="1080P神器" /> <img src="images/door2.png" alt="5.5寸四核" title="5.5寸四核" /> <img src="images/door3.png" alt="四核5寸" title="四核5寸" /> <img src="images/door4.png" alt="5.7寸机皇" title="5.7寸机皇" /> </div> </body> </html>
css:
#container { height: 477px; margin: 0 auto; border-right: 1px solid #ccc; border-bottom: 1px solid #ccc; overflow: hidden; position: relative; } #container img { position: absolute; display: block; left: 0; border-left: 1px solid #ccc; }
js操作:
window.onload = function() { //容器对象 var box = document.getElementById('container'); //获得图片NodeList对象集合 var imgs = box.getElementsByTagName('img'); //单张图片的宽度 var imgWidth = imgs[0].offsetWidth; //设置掩藏门体露出的宽度 var exposeWidth = 180; //设置容器总宽度 var boxWidth = imgWidth + (imgs.length - 1) * exposeWidth; box.style.width = boxWidth + 'px'; //设置每道门的初始位置 function setImgsPos() { for (var i = 1, len = imgs.length; i < len; i++) { imgs[i].style.left = imgWidth + exposeWidth * (i - 1) + 'px'; } } setImgsPos(); //计算每道门打开时应移动的距离 var translate = imgWidth - exposeWidth; //为每道门绑定事件 for (var i = 0, len = imgs.length; i < len; i++) { //使用立即调用的函数表答式,为了获得不同的i值 (function(i) { imgs[i].onmouseover = function() { //先将每道门复位 setImgsPos(); //打开门 for (var j = 1; j <= i; j++) { imgs[j].style.left = parseInt(imgs[j].style.left, 10) - translate + 'px'; //imgs[j].style.left = j*exposeWidth +"px"; } }; imgs[i].onmouseout = function(){ setImgPos(); }; })(i); } };
希望本文所述对大家学习javascript程序设计有所帮助。
