javascript图片轮播代码,供大家参考,具体内容如下
因为自己是新手自学不久,所以代码有很多不规范的地方,请原谅。
html部分代码:
<div> <button onmousedown="p()"><</button> <img src="https://www.jb51.net/image/dell.jpg" alt="Dell"> <button onmousedown="n()">></button> </div>
CSS部分代码:
<style type="text/css"> * { margin: 0; padding: 0; } #head { width:800px; height:500px; border-radius: 5px; border: 2px solid pink; margin: 200px auto; text-align: center; } #prev { width: 30px; height: 30px; border: 0px; border-radius: 5px; background-color:white; color: black; position: relative; margin-top: 250px; float: left; } #next { width: 30px; height: 30px; border: 0px; border-radius: 5px; background-color:white; color: black; position: relative; margin-top: 250px; float: right; } </style>
javascript部分代码:
<script> var prev=document.getElementById("prev"); var next=document.getElementById("next"); var img=document.getElementsByTagName("img")[0]; var imgArr=["image/dell.jpg/dell.jpg","image/dell.jpg/sony.jpg","image/dell.jpg/费列罗.jpg","image/dell.jpg/Nike.jpg"]; var index=0; //点击左箭头,切换上一张 function p(){ if(index==0) { index=imgArr.length; } index--; img.src=imgArr[index]; } //点击右箭头,切换下一张 function n(){ if(index==imgArr.length) { index=0; } img.src=imgArr[index]; index++; } //设置自动播放 time=setInterval("p()",2000); //鼠标移入箭头内,停止自动播放 function cal(){ clearInterval(time); } </script>
