js菜鸟求解?图片自动切换问题,
图片自动切换有问题,从第一个一下就切换到最后,中间两个没播放,代码如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
// <link rel="Stylesheet" type="text/css" href="lunbot.css"/>
<script type="text/javascript" src="lunbo.js"></script>
</head>
<body>
<div id="a">
<ul>
<li class="b">1</li>
<li>2</li>
<li>3</li>
<li>4</li>
</ul>
<div id="c">
<img id="img" src="imgs/p1.jpg" />
</div>
</div>
</body>
</html>
js代码如下:
var imgArry = ["imgs/p1.jpg", "imgs/p2.jpg", "imgs/p3.jpg", "imgs/p4.jpg"];
var img1;
var i;
window.onload = function () {
img1 = document.getElementById("img");
setInterval(show, 2000);
function show()
{
for (i = 0; i < imgArry.length; i++)
{
img1.setAttribute("src", imgArry[i]);
}
}
};
------解决方案--------------------[code=JSscrpt]
var arr=new Array();
arr[0]="imgs/p1.jpg";//放图片地址
arr[1]="imgs/p2.jpg";
arr[2]="imgs/p3.jpg";
arr[3]="imgs/p4.jpg";
var num=0;
setInterval(turnpic,4000); //每隔4秒转换图片
function turnpic(){
idsrc=document.getElementById("img");
if(num==arr.length-1)
num=0;
else
num+=1;
idsrc.src=arr[num];
}
[/code]
------解决方案--------------------JScript code
var arr=new Array();
arr[0]="imgs/p1.jpg";//放图片地址
arr[1]="imgs/p2.jpg";
arr[2]="imgs/p3.jpg";
arr[3]="imgs/p4.jpg";
var num=0;
setInterval(turnpic,4000); //每隔4秒转换图片
function turnpic(){
idsrc=document.getElementById("img");
if(num==arr.length-1)
num=0;
else
num+=1;
idsrc.src=arr[num];
}
------解决方案--------------------
for (i = 0; i < imgArry.length; i++)
{
img1.setAttribute("src", imgArry[i]);
},
到头了自然就不跑了,i == imgarry.length-1的时候i-1就可以了
------解决方案--------------------
var imgArry = ["imgs/p1.jpg", "imgs/p2.jpg", "imgs/p3.jpg", "imgs/p4.jpg"];
var img1;
var i;
window.onload = function () {
img1 = document.getElementById("img");
setInterval(show, 2000);
function show()
{
img1.setAttribute("src", imgArry[i]);
i++
}
};
------解决方案--------------------
应该是这样
var imgArry = ["imgs/p1.jpg", "imgs/p2.jpg", "imgs/p3.jpg", "imgs/p4.jpg"];
var img1;
var i;
window.onload = function () {
img1 = document.getElementById("img");
setInterval(show, 2000);
function show()
{
img1.setAttribute("src", imgArry[i]);
i++
if(i==imgArry.length)i = 0;
}
